Components Required: Arduino board (e.g., Arduino Uno) DHT11 sensor 10kΩ resistor (optional, if required by your sensor module) Jumper wires Circuit Connection: VCC (DHT11) → 5V (Arduino) GND (DHT11) ...

This is a tutorial how to send DHT11 sensor data using Arduino Uno to IOTA Tangle using Masked Authenticated Messaging (MAM).

The DHT11 sensor senses the surrounding room temperature and gives the result in degrees Celsius. Both the reference and the measured values are displayed on the Liquid Crystal Display (LCD). The ...

For DHT11 sensor, the decimal bytes of temperature and humidity measurements are always zero. Therefore, the first and third bytes of received data actually give the numeric values of the measured ...
