Description
The AZDelivery DHT22/AM2302 is a low cost, reliable digital temperature and humidity sensor and the successor of the widely used DHT11. This module is suitable for both 5V and 3.3V microcontrollers.

Particularities
- Using capacitive moisture sensor and hot conductor, the sensor measures surrounding air data and passes these values further as a digital signal to the data PIN (no analog input pins are required).
- For advanced users, the sensor module can also be controlled directly, without library.
