DHT11 Temperature and Humidity Sensor

The DHT11 is a low-cost humidity and temperature sensor with a digital interface, featuring a 1-Wire connection. The sensor is already factory calibrated, but does not have such a high resolution. If you want a higher resolution and better accuracy, we also recommend the DHT22. You can find a ready-made Arduino library for control in the Library Manager under “DHT Sensor Library”. The resistors needed for control are already installed on the board. So you can simply plug the board into your Arduino and get started.

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