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 factory calibrated, but it does not have a high resolution. If you want higher resolution and better accuracy, we also recommend the DHT22. A ready-to-use Arduino Library for controlling the sensor can be found in the Library Manager under "DHT Sensor Library". The necessary resistors for control are already installed on the board. This allows you to easily connect the board to your Arduino and get started.

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