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

When the critical infrastructure that so many of us take for granted goes away, how do we organize ourselves and our communities to respond?

If recent ecological disasters have demonstrated anything, it is the inadequacy of existing models and tools to provide efficient allocation of resources, access to emergency communications, and effective coordination of human effort. Few if any solutions exist that are off-grid, affordable, reliable, easily deployed, and openly standardized.

...

disaster.radio is an off-grid, solar-powered, long-range mesh network built on free, open source software and affordable, open hardware.  

Designed to be open, distributed, and decentralized, disaster.radio is currently in the prototype/development phase. To learn more about the technologies driving our development, visit the following pages:

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.
