DHT22 Temperature and Humidity Sensor Plug-in
The DHT22 has a calibrated AM2302 sensor built in, which allows you to measure temperature and humidity. Compared to the affordable DHT11, the DHT22 offers a higher accuracy and a larger measurement range. The sensor is equipped with a XH2.54mm connector, allowing you to connect custom crimped cables to the sensor easily. The DHT22 is controlled via a digital 1-wire interface, making it easy to operate with an Arduino or ESP8266. You can find a pre-made Arduino library for controlling it in the Library Manager under "DHT Sensor Library". The board already comes with the resistors needed for controlling, meaning you can easily attach the board to your Arduino and get started.
Application examples for the DHT22:
- Weather station
- Air tube
- Humidity control
- Temperature control
- Measuring room temperature and humidity
- Test and detection device
