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, facilitating operation with an Arduino or ESP8266. A ready-to-use Arduino library for control can be found in the Library Manager under "DHT Sensor Library." The board already has the necessary resistors built-in, so you can simply plug it into your Arduino and get started.
