DHT22 Temperature and Humidity Sensor

The DHT22 AM2302 is a cost-effective humidity and temperature sensor with a digital interface, featuring a 1-wire connection. The sensor comes factory-calibrated and has a high resolution. You can find a ready-to-use Arduino library for control in the Library Manager under "DHT Sensor Library". The resistors needed for control are already built into the board. So you can easily plug the board into your Arduino and get started.

If you have any questions or problems with control, or suggestions for the product description, just send us an email or use the rating function. We are happy to help.
