WaveShare DHT22 temperature and humidity sensor pluggable

The DHT22 is equipped with a calibrated AM2302 sensor that allows for the measurement of temperature and humidity. Compared to the budget-friendly DHT11, the DHT22 offers higher accuracy and a wider measurement range. The sensor features an XH2.54mm connector, making it easy to connect your own crimped cables. The DHT22 is controlled via a digital 1-Wire interface, which simplifies operation with an Arduino or ESP8266. You can find a ready-made Arduino library for control in the Library Manager under "DHT Sensor Library." The board already has the necessary resistors installed, so you can simply plug the board into your Arduino and get started.
