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.
