Transferência de Arquivos via LoRa

Um projeto que venho fazendo há alguns meses e que muitas pessoas estavam interessadas em transmitir imagens e agora será possível, mas claro, respeitando as limitações.

Transferência da arquivos via LoRa é possível assim como qualquer outra modulação, mas existem desafios particulares nessa tarefa que em outras modulações podem ser mais fáceis.  Sobre a modulação LoRa Antes mesmo de partimos para a transferência de arquivos via LoRa, é preciso entender que o LoRa não foi feito para esse tipo de aplicação e sim para dispositivos IoT, mesmo embora tenha uma taxa…

A farming Arduino

Arduino Pro redefines smart agriculture with the new Edge Control

_

Experience the intelligent future of outdoor environments Arduino Pro announces the launch of the Arduino Edge Control, a smart remote solution for monitoring and control, designed to deploy AI on the edge. Optimized for outdoor environments and easy to place anywhere, it is ideal for precision farming, smart agriculture, and any application requiring intelligent control in isolated locations.The Arduino Edge Control can be expanded with 2G, 3G, CatM1, or NB-IoT modems, Lora, Sigfox, Wi-Fi, or Bluetooth connectivity; it can be managed remotely via the Arduino Cloud or third-party solutions and powered via solar panels. The option to power the device via solar panels as well as the range of connectivity options means the Edge Control can be used in the most remote of locations and monitored from afar. The Arduino Edge Control is able to connect sensors, provide real-time monitoring and automatically drive actuators – such as latching valves commonly used in agriculture – reducing production-related risks. Through this advanced solution, smart agriculture sensors collect data about weather conditions, soil quality, crop growth, and more. The data is then sent to the Arduino IoT Cloud, where valuable analytics can be retained to support business at different levels – enabling better decisions about equipment efficiency, plant growth, and staff productivity, or even automating processes such as fertilization, irrigation, and pest control to boost the quality of crops and minimize human error. During product development, Arduino partnered with Challenge Agriculture to integrate the Edge Control into Irriduo®, the French company's new smart irrigation solution and water management application, the first in a new generation of water management products. Combining Challenge Agriculture's R2-DX with the Arduino Edge Control , Arduino MKR GSM1400 for connectivity and firmware, and including access to a dedicated cloud, Irriduo® takes a closer look at the soil to actively tell farmers how to achieve the best yield while minimizing water consumption and maximizing soil preservation. The inherent nature of arable farming sets its own unique set of challenges: remote locations, changeable soil conditions based on field topography, and specific crop rotation schedules to mention but a few. Challenge Agriculture and Arduino worked to create an optimal solution for these needs, with 6 sensors per field providing accurate readings for 6 crop cycles of 3-4 months each (i.e. 4,000 measurements), or for as long as 4 years in the case of perennial crops. Constant sensing and monitoring are only half the story - by automating irrigation controls, Irriduo® also reacts in real-time to changing conditions. This is especially important in regions suffering from droughts, where strict regulations are enforced to limit the volume of water that can be used and the time of day/night irrigation can be activated. Commenting on the launch, Arduino’s CEO Fabio Violante said, “People are constantly needing to solve everyday problems and improve productivity through their own creativity and ingenuity, and we truly believe they can do this with the Edge Control. We are ready to help companies take the next step in agricultural automation, providing smart irrigation solutions and the ability to apply machine learning on the edge to optimize crop production and increase yields.” Xavier Eftimakis, Founder & CEO at Challenge Agriculture, added, “The Edge Control allows many cost-effective solutions for multiple smart agriculture projects.” The Edge Control’s robust design and solar-powered capabilities mean that it is suited for controlling applications in any outdoor environment. For example, it can be used on construction sites and real estate to monitor and automate access control; moreover, swimming pool maintenance and cleaning companies could take advantage of its capabilities to change their service offering by monitoring and controlling the condition of the pool water remotely. As usual, it is expected that countless ingenious solutions will be provided by the Arduino community using this technology. The Arduino Edge Control is available for €166/US$199 on the Arduino Store. For more information, please visit: arduino.cc/pro

Hack and Tell #26

This time we had 4 interesting presentations

To no one's great surprise, the 26th Hack&Tell began with the Photography Turntable: Part Two, told by Darius. Those who attended the previous Hack&Tell, know that the first iteration of this project turned out to be somewhat limited due to the friction and lack of rigidity, that the stepper motor could not overcome. This time, Darius used a larger, more robust case, a powerful PSU from a PC, and a Raspberry Pi to control it all. Since photography is a light-sensitive matter, the feedback from this device was provided by a synthesized voice, speaking (or cursing) in Russian, as the Lithuanian variant was simply incomprehensible. This time, PCB was milled rather than etched. There was a more though-out gear and belt reduction system, and a ball bearing to support larger weights on the turntable top. With a white background stand and light-diffusing fabric, the device finally works like intended and can be used to take pictures of objects as large as a CRT TV. 

Next, Marius made a shot for the stars with a telescope project. The inspiration for it came from the book "How to make a telescope" by J. Texereau, which described the procedure of grounding telescope mirrors but omitted the explanation of how they should be aluminized. Because of that, the idea was put on hold, but then, during the Makerspace clean-up effort, Marius adopted an old video projector that was about to be thrown out and decided to use its lense to build a Keplerian telescope. This type of telescope does not require precisely grounded lenses, nor a very accurate assembly and the math behind the dimensions is quite simple. Using a cylindrical bottle box, a cut-off PVC pipe, and another, little lense from a microscope, Marius assembled it all and even took a few test shots. Now, all that remains is a more robust frame, a tripod mounting point, and a proper attachment for a photo camera. 

Hack&Tell continued with Renardas story about a remotely controlled lamp that he developed from scratch to a final product, after being contracted by local hunters who needed illumination for specific spots in their hunting grounds. Since this lamp is operated off a custom made 18650 LiPo cell battery bank, it required a reliable, long-range, power-saving method of communication, LoRa fit that description perfectly. After testing data transfers between two Arduino Nano microcontrollers connected to LoRa receivers-transmitters, Renardas soldered it all on perf-boards and housed in separate plastic cases. The lamp itself was a high-powered LED, so powerful that it even required a heat sink. Even though this project took much more time and money than initially intended, Renardas delivered the final product without compromise and even wrote a user manual for it. Heres the link to his blogpost http://9v.lt/blog/remote-controlled-outdoor-light/

Finally, Justinas told us about a small-scale model of a sailing dinghy that he is developing and planning to construct a full-scale next summer. The key point of this design is a double floor - an air-tight compartment that provides extra buoyancy and allows the boat to bail the water through the transom without the need for the sailor to waste his time with a bucket during a race. This boat was designed with Solidworks, scaled-down, parts were flattened and designed to fit on two A4 cardboard sheets, and then cut out with Makerspace laser cutter. The tiny pieces were then glued together, the assembled model was varnished for waterproofing, and tested out in the sink. The double floor and water bailing system worked fine, but testing revealed that the stability of this boat isn't that great, and will require further improvements to make it viable for a full-scale build. Perhaps there will be a Part Two for this project as well? 

After a nerve-stretching vote, Darius continued his invincible winning streak with yet another victory. The bar is set really high now...

IoT Standards & Protocols Guide - Arya College

The essence of IoT is networking that students of information technology college should be followed. In other words, technologies will use in IoT with a set protocol that they will use for communications. In Communication, a protocol is basically a set of rules and guidelines for transferring data. Rules defined for every step and process during communication between two or more computers. Networks must follow certain rules to successfully transmit data.

While working on a project, there are some requirements that must be completed like speed, range, utility, power, discoverability, etc. and a protocol can easily help them find a way to understand and solve the problem. Some of them includes the following:

The List

There are some most popular IoT protocols that the engineers of Top Engineering Colleges in India should know. These are primarily wireless network IoT protocols.

Bluetooth

Bluetooth is a wireless technology standard for exchanging data over some short distances ranges from fixed and mobile devices, and building personal area networks (PANs). It invented by Dutch electrical engineer, that is, Jaap Haartsen who is working for telecom vendor Ericsson in 1994. It was originally developed as a wireless alternative to RS-232 data cables.

ZigBee

ZigBee is an IEEE 802.15.4-based specification for a suite of high-level communication protocols that are used by the students of best engineering colleges to create personal area networks. It includes small, low-power digital radios like medical device data collection, home automation, and other low-power low-bandwidth needs, designed for small scale projects which need wireless connection. Hence, ZigBee is a low data rate, low-power, and close proximity wireless ad hoc network.

Z-wave

Z-Wave – a wireless communications protocol used by the students of Top Information Technology Colleges primarily for home automation. It is a mesh network using low-energy radio waves to communicate from appliance to appliance which allows wireless control of residential appliances and other devices like lighting control, thermostats, security systems, windows, locks, swimming pools and garage door openers.

Thread

A very new IP-based IPv6 networking protocols aims at the home automation environment is Thread. It is based on 6LowPAN and also like it; it is not an IoT protocols like Bluetooth or ZigBee. However, it primarily designed as a complement to Wi-Fi and recognises that Wi-Fi is good for many consumer devices with limitations for use in a home automation setup.

Wi-Fi

Wi-Fi is a technology for wireless local area networking with devices according to the IEEE 802.11 standards. The Wi-Fi is a trademark of the Wi-Fi Alliance which prohibits the use of the term Wi-Fi Certified to products that can successfully complete interoperability certification testing.

Devices that can use Wi-Fi technology mainly include personal computers, digital cameras, video-game consoles, smartphones and tablets, smart TVs, digital audio players and modern printers. Wi-Fi compatible devices can connect to the Internet through WLAN and a wireless access point. Such an access point has a range of about 20 meters indoors with a greater range outdoors. Hotspot coverage can be as small as a single room with walls that restricts radio waves, or as large as many square kilometres that is achieved by using multiple overlapping access points.

LoRaWAN

LoRaWAN a media access control protocol mainly used for wide area networks. It designed to enable students of private engineering colleges in India to communicate through low-powered devices with Internet-connected applications over long-range wireless connections. LoRaWAN can be mapped to the second and third layer of the OSI model. It also implemented on top of LoRa or FSK modulation in industrial, scientific and medical (ISM) radio bands.

NFC

Near-field communication is a set of communication protocols that enable students of best engineering colleges in India two electronic devices. One of them is usually a portable device like a smartphone, to establish communication by bringing them within 4cm (1.6 in) of each other.

These devices used in contactless payment systems like to those used in credit cards and electronic ticket smartcards and enable mobile payment to replace/supplement these systems. Sometimes, this referred to as NFC/CTLS (Contactless) or CTLS NFC. NFC used for social networking, for sharing contacts, videos, photos,or files. NFC-enabled devices can act as electronic identity both documents and keycards. NFC also offers a low-speed connection with simple setup that can be used by the students of top btech colleges in India to bootstrap more capable wireless connections.

Cellular

IoT application that requires operation over longer distances can take benefits of GSM/3G/4G cellular communication capabilities. While cellular is clearly capable of sending high quantities of data. Especially for 4G with the expense and also power consumption will be too high for many applications. Also, it can ideal for sensor-based low-bandwidth-data projects that will send very low amounts of data over the Internet. A key product in this area is the SparqEE range of products including the original tiny CELLv1.0 low-cost development board and a series of shield connecting boards for use with the Raspberry Pi and Arduino platforms.

Sigfox

This unique approach in the world of wireless connectivity; where there is no signalling overhead, a compact and optimized protocol; and where objects not attached to the network. So, Sigfox offers a software-based communications solution to the students of top engineering colleges in India. Where all the network and computing complexity managed in the Cloud, rather than on the devices. All that together, it drastically reduces energy consumption and costs of connected devices.

SigFox wireless technology is based on LTN (Low Throughput Network). A wide area network-based technology which supports low data rate communication over larger distances. However, it mainly used for M2M and IoT applications which transmits only few bytes per day.

Hardware solutions for Eclipse IOT Challenge: Exploring LoRa/LoRaWAN

The Eclipse IOT challenge lead me to research more in depth different technologies both from the hardware and the software aspect. As part of product development and delivery one has to come up with the solution for a problem. In this case the problem is parking in urban areas, or the lack of smarter parking solutions. Such implementation would not only allow end users to have a better parking experience while saving time in finding an adequate spots but also provides the city with valuable data to be used for city planning and city improvement projects.

Once the issue is identified, it was important to find a technical solution that would align with our needs. For city implementations, given the broad area that needs to be covered, we would need a type of communication that is long range and low cost, both in cost of sending data and power consumption. I first tackled the hardware needs once the design was evaluated. The prototype for a smart city solution needs to also be scalable while adding the least overhead in cost and infrastructure needed.

In this article I will go more in depth on the research done to identify one of the key components of the project. I will share a summary of my findings in hopes of helping others that are also exploring similar solutions.

Evaluating communication solutions:

I evaluated BLE, bluetooth, cellular, satellite, Wi-Fi, SigFox, Zigbee and Lora. Bluetooth and Wi-Fi, given its range limitation and cost were not considered for this prototype. Cellular communications have a higher cost as well, and at even steeper price comes satellite communication; both this options were also discarded. SigFox and LoRa/LoraWAN were the runner up candidates. I came across a comprehensive post on the comparison of SigFox and LoRa that is worth the read https://www.link-labs.com/blog/sigfox-vs-lora . The winner was LoRa.

Why Lora?

As explained by Libelium on http://www.libelium.com/development/waspmote/documentation/lora-vs-lorawan/ LoRa contains only the link layer protocol and is perfect to be used in P2P communications between nodes. LoRa modules are a little cheaper that the LoRaWAN ones.. LoRaWAN includes the network layer too so it is possible to send the information to any Base Station already connected to a Cloud platform. LoRaWAN modules may work in different frequencies by just connecting the right antenna to its socket..

LoRa which stands for long range wireless operates at a low bandwidth, meaning that its best application is for sending smaller pieces of data such as sensor data. LoRaWAN is known for its good penetration and long coverage which has been recorded to reach over 10 KM distance. LoRaWAN operates on unlicensed bands, so in most countries is legal to have you own LoRaWAN gateway cutting down the cost given that you will not have to pay a carrier or third party to supply you with the service.

Additionally a selling point for me personally was the wide accessibility to various developer platforms and hardware solutions such as DIY LoRa kits, libraries and Arduino compatible LoRa modules. The Things Network offers a strong platform with access to resources, documentation and a great community of IOT LoRa enthusiast.

Gateway

Lets take a look at one of the hardware pieces now. “Gateways form the bridge between devices and The Things Network. Devices use low power networks like LoRaWAN to connect to the Gateway, while the Gateway uses high bandwidth networks like WiFi, Ethernet or Cellular to connect to The Things Network. Gateways are routers equipped with a LoRa concentrator, allowing them to receive LoRa packets”(see more at https://www.thethingsnetwork.org/docs/gateways/). Below is a list of some gateways that were evaluated for this project. I spent time looking at their platform flexibility, the documentation and support provided and what would be the most cost effective solution for a minimum viable product (MVP).

A DIY low-cost LoRa gateway

http://cpham.perso.univ-pau.fr/LORA/RPIgateway.html

The gateway is based on a Raspberry PI. RPI 1B+/2B/3B can be used. The LoRa modules comes from (a) Libelium LoRa radio module, (b) HopeRF RFM92W/HopeRF RFM95W (or RFM96W for 433MHz), © Modtronix inAir9/inAir9B (or inAir4 for 433MHz), (d) NiceRF LoRa1276. Libelium LoRa and RFM92W use the Semtech SX1272 chip while RFM95W, inAir9/9B and NiceRF LoRa1276 use the SX1276 which is actually more versatile.

Note: The LoRa module and the LoRaWAN module are not compatible because the protocols are different. The LoRa module implements a simple link protocol, created by Libelium. However, the LoRaWAN module runs the LoRaWAN protocol, a much richer and more advanced protocol, created by the LoRa Alliance.

Check out their Github page with detailed documentation https://github.com/CongducPham/LowCostLoRaGw

Conclusion on gateways:

The gateway is a key portion of this solution given that the sensors will need to send the information “somewhere” where it can either be analyzed on the edge or sent to the cloud. After considering price ranges on both the parts needed for a DIY solution or a full blown gateway I considered those solutions that would be cost effective and which I was most familiar with. The “LG01 LoRa OpenWrt IoT Gateway by Dragino Tech” seemed the best approach. The developer kit counts with an Arduino developer node and a Developer gateway. Note that this solution only counts with ONE channel, in comparison with other solutions that allow 8+ channels. This was a compromise that was evaluated and given that this will be a prototype the one channel option seemed sufficient.

In the following articles I will showcase both the remaining hardware parts and the software portion along with updates on how the project is coming along.

Pinoy-made ocean waste collector and dengue mapper to join the NASA global hackathon

MANILA, Philippines - A deployable, autonomous ocean waste collection system utilizing space data to locate nearby garbage patches built by students from De La Salle University and an automated information portal which correlates dengue cases with real-time data from satellite, climate, and search engines won the National Aeronautics and Space Administration's International Space Apps Challenge last October 18-20, 2019 in Manila, in collaboration with the Philippine Council for Industry, Energy and Emerging Technology Research and Development of the Department of Science and Technology (DOST-PCIEERD), Animo Labs technology business incubator, PLDT InnoLab, American Corner Manila, the U.S. government, and part of the Design Week Philippines with Department of Trade and Industry-Design Center of the Philippines.

Using NASA's Ocean Surface Current Analysis Real-time (OSCAR) data to determine possible locations of ocean garbage patches using GPS, PaWiKAN uses a pair of deployable, dynamically reconfigurable boats capable of trapping and returning ocean waste back to ground. It is equipped with extended-range radio system based on LoRa technology and Arduino to communicate with sensors and controlled by a deployment station. It was developed by Lasallian electronics and communications engineering students Samantha Maxine Santos, Antonio Miguel S. Alejo, Grant Lewis Bulaong, and Janos Lance L. Tiberio of Ocean's 4, who also joined the last year's hackathon, creating a hyper-casual puzzle game utilizing images from the Hubble Space Telescope and intuitive physics concepts.

"Our global bodies of water are actually littered with plastics. This is a very futuristic solution to help get rid of plastics currently floating or submerged in global waters. It is timely and relevant solution," according to Monchito B. Ibrahim, Industry Development Committee Chairman of the Analytics Association of the Philippines and former undersecretary of the Department of Information and Communications Technology.

With 271,480 dengue cases resulting in 1,107 deaths as reported from January 1 to August 31, 2019 by the World Health Organization, the Aedes Project team composed of Dominic Vincent D. Ligot, Mark Toledo, Frances Claire Tayco, and Jansen Dumaliang Lopez developed a forecasting model of dengue cases using climate and digital data and pinpointing possible hotspots from satellite data. Correlating information from Sentinel-2 Copernicus and Landsat 8 satellites, DOST-PAGASA for climate, and trends from search engines, potential dengue hotspots will be displayed in a web interface. Indices like Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) and Normalized Difference Vegetation Index (NDVI) are used in identifying areas with green vegetation while Normalized Difference Water Index (NDWI) to identify areas with water. Combining these indices reveal potential areas of stagnant water capable of being breeding grounds of mosquitoes.

"It benefits the community especially those countries suffering from malaria and dengue, just like the Philippines. I think it has a global impact. This is the new science to know the potential areas where dengue might occur. It is a good app," said Engr. Raul C. Sabularse, deputy executive director of DOST-PCIEERD.

"It is very relevant to the Philippines and other countries which usually having problems with dengue. The team was able to show that it's not really difficult to have all the data you need and integrate all of them and make them accessible to everyone for them to be able to use it. It's a working model. It is something can actually be made usable in a short span of six months," Mr. Ibrahim said.

Space Apps leader Dr. Paula S. Bontempi, the acting deputy director of the Earth Science Mission, NASA's Science Mission Directorate was impressed of these solutions presented in Manila, "The top two are really good. There were definitely a few projects right behind them. There is a lot of good talent out there. It was nice to see."

Rex Lor from United Nations Development Programme in the Philippines commended the use of the Sustainable Development Goals on Good Health and Well-Being, and Life Below Water of the winning solutions showcasing the "pivotal role of cutting-edge digital technologies in the creation of strategies for sustainable development in the face of evolving development issues."

Both champions will join teams around the world to be evaluated by NASA to approximately select the top 30 projects as global finalists in early December, and the top six winners will be announced in January 2020. Winners shall be invited to visit the NASA’s Kennedy Space Center at Florida in 2020.

Last year, team iNON used a citizen science platform by NASA to develop an application seeking to communicate scientific data to fishermen even without Internet connection, which led them to victory as the first Pinoy global winner. Their project called ISDApp is currently being incubated by Animo Labs.

University president Br. Raymundo B. Suplido FSC hopes that NASA Space Apps would "encourage our young Filipino researchers and scientists to create ideas and startups based on space science and technology, and pave the way for the promotion and awareness of the programs of our own Philippine space agency."

Vice President Leni Robredo recognized Space Apps as a platform "where some of our country's brightest minds can collaborate in finding and creating solutions to our most pressing problems, not just in space, but more importantly here on Earth."

"Space Apps is a community of scientists and engineers, artists and hackers coming together to address key issues here on Earth. At the heart of Space Apps are data that come to us from spacecraft flying around Earth and are looking at our world," as explained by Dr. Thomas Zurbuchen, NASA associate administrator for science.
