This DHT22 Digital Temperature & Humidity Sensor is a low-cost module that uses a capacitive humidity sensor and a thermistor for accurate measurements. It provides precise relative humidity and temperature readings with a humidity measurement precision of 2-5% RH and temperature measurement precision of 0.5°C.
Simply connect the first pin to 3-5V power, the second pin to your data input pin, and the rightmost pin to the ground. Please note that each sensor must have its own data pin if you want to use multiple sensors.
