This Arduino project reads data from DHT11 and DHT22 sensors to measure temperature and humidity. The DHT11 sensor is a basic and affordable option, while the DHT22 sensor provides higher accuracy.

This is a tutorial how to send DHT11 sensor data using Arduino Uno to IOTA Tangle using Masked Authenticated Messaging (MAM). The project consists of 4 main files and should be executed on a computer.

VCC is the power supply pin of the soil moisture sensor that can be connected to 3.3V or 5V of the supply. But do note that the analog output will vary depending on the provided supply voltage. GND is ...
