Description

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.
