Description

Grove ?? DHT22 is a high accuracy temperature and humidity sensor based on the DHT22 module (also known as AM2302 or RHT03). High-cost performance and high precision make it ideal for temperature and humidity monitoring of Arduino and Raspberry Pi, you can also use it to make a thermometer and hygrometer.

The DHT22 includes a capacitive humidity sensor and a high precision temperature sensor. The range of humidity sensor is 0 to 99.9 %RH with ?2% accuracy while the temperature sensor ranges from -40 to 80?? with ?0.5?? accuracy. With the help of a built-in 8-bit microcontroller, the DHT22 converts the analogue output of those two sensors to the digital signal, and outputs both temperature and humidity data via a single pin.
