DHT22 DHT-22 Digital Temperature & Humidity Sensor Temperature Sensor Made Hygrometer Humidity & Temperature Controller AM2302 Replace DHT11 DHT21 18B20 LM25Dz SHT11 SHT15 Sensors

DHT22 includes a capacitive moisture sensor and a NTC temperature measuring element which is connected to a high-performance 8-bit microcontroller, resulting an excellent quality, super fast response time, strong anti-interference ability and extremely cost-efficient.

Compared with SHT10 temperature and humiditiy sensor, DHT22 enjoys a higher precision and lower price, making it an ideal choice for mid price range, high performance temperature & humidity sensors.

If used together with Arduino expansion boards, you’ll easily get interactives of correlation between temperature and humidity perception.
