IoT based Smart Shopping Cart using RFID and NodeMCU

We all have waited in a queue for payment in shopping malls and other places, its very tiring and wastes a lot of time in the billing process. Today we will build a smart shopping cart with an automatic billing system that not only reduces the waiting time but also makes the process very smooth and easy.

Here we use RFID cards and RFID readers with NodeMCU to build the Smart Shopping Cart project. The cart information and total value will be displayed on the webpage as well as on LCD.

IoT based ESP32 Wi-Fi Weather Station using DHT11 and BMP180 Sensor

In this tutorial, we will make an ESP32 based Weather station in which we will build an ESP32 Webserver to display temperature, humidity, pressure, luminosity, and altitude values on a web browser. Here DHT11 sensor is used to get the temperature and humidity data, BMP180 is used to get pressure and altitude data, and an LDR is used to get Luminosity data. This weather data can be monitored from anywhere in the world using the IP address of ESP32. It can also be uploaded to ThingSpeak to make it more interactive as we have done in Raspberry Pi weather station.

In IoT based applications, Webservers are used to control or monitor any sensor values using web browsers, we previously created many webservers using Arduino, ESP8266, NodeMCU, ESP32, Raspberry Pi, etc.

Environment Sensing Development Board RIOT-001 from RICOH to Test and Develop IoT Edge Devices

Ricoh Electronic Devices Company has introduced an environment sensing board, RIOT-001 that can be used in demonstration experiments of IoT devices. The board monitors ambient temperature, humidity, air pressure, and brightness. The information that RIOT-001 transmits with its Bluetooth Low Energy (BLE) once per five seconds can be displayed on smartphones/tablets where an application programmed for the RIOT-001 is installed.

IoT based Smart Door Lock System using NodeMCU

In this project, we are going to make an IOT based Door Lock System using NodeMCU, Solenoid Lock, and Adafruit IO. Here NodeMCU will act as the main controller and connect the user to the door lock system using the Internet. This allows the user to lock/unlock his Home’s door lock by using a smartphone from anywhere in the world.

IoT Based Smart Currency Counter using NodeMCU and Arduino IDE

Currency note counter is a machine that detects the notes of different denominations and tells its value. Here in this IoT project, we are using a color sensing technique to detect the note value. So, here we will use the TCS230 color sensor with NodeMCU ESP8266 to detect the currency value and display the same on a webpage as well as on 16x2 LCD.

IoT Based Food Monitoring System

In this IoT project, we will build a Food Monitoring device using NodeMCU and Arduino IDE, to monitor the temperature and humidity of the stored environment and control it. To control the temperature, we are going to use a DC motor as a cooling mechanism. To find the temperature, and humidity the DHT11 sensor module is used, and to determine the status of the food, the MQ4 gas sensor module is used. In the future, if needed we can also use an IoT based Weight sensor to also monitor the food quantity in the storage area:
