✔️ The DHT22 is a reliable sensor for determining temperature and humidity.
✔️ Since the sensor can be operated with 3.3V as well as 5V, it is suitable for connection to all common boards like RN-Control, Raspberry Pi and all other microcontrollers.
✔️ Besides the operating voltage, only one port needs to be connected to the sensor.
✔️ The output is serial as a digital bit sequence. This makes the sensor ideal for monitoring the indoor climate or setting up a weather station.
