DHT22 AM2302 Temperature sensor and humidity sensor

The AZDelivery DHT22 is a reliable sensor for determining temperature and humidity. As the sensor can be operated with both 3.3V and 5V, it is suitable for connection to all common boards such as RN-Control, Raspberry Pi and all other microcontrollers. In addition to 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 building a weather station.

Special features

Compared to the DHT11 temperature sensor, this module enables greater precision in temperature and humidity measurement. You do not need any additional components to integrate the sensor into your projects. Thanks to its small dimensions, low power consumption and long transmission distance (100 m), the AM2302 is suitable for all types of harsh operating conditions.
