Gravity DHT22 Temperature and Humidity Sensor

The DHT22 is a digital module that contains both a temperature and humidity sensor. These are calibrated and have digital signal outputs. Through a special digital module collection technology and sensor technology, it ensures high reliability and stability. The sensor is equipped with a built-in 8-bit microcontroller and has a fast response time as well as a low power consumption with small size. The DHT22 module can easily be integrated into a system and is suitable for a variety of applications. Compared to the more expensive SHT10 sensor, it offers higher precision and can achieve interactive effects when combined with an Arduino extension board.
