Grove Temperature and Humidity Sensor Pro(DHT22) is a high-precision temperature and humidity sensor
- Grove-DHT22 is a high-precision temperature and humidity sensor based on the DHT22 module (also known as AM2302 or RHT03). Its high cost performance and high precision make it highly suitable for temperature and humidity monitoring on Arduino and RaspberryPi. You can also use it to make thermometers and hygrometers.
- The DHT22 includes a capacitive humidity sensor and a high-precision temperature sensor. The range of the humidity sensor is 0 to 99.9%RH with an accuracy of ± 2%, while the range of the temperature sensor is -40 to 80° C with an accuracy of ± 0.5° C. With the built-in 8-bit microcontroller, the DHT22 converts the analog outputs of these two sensors into digital signals and outputs temperature and humidity data through a single pin.
