The DHT22 is a capacitive humidity sensing digital temperature and humidity module that contains a calibrated digital signal output of temperature and humidity sensors. It is designed with a dedicated digital-signal-collecting-technique and humidity sensing technology, assuring its reliability and stability. The sensor includes a capacitive sensor wet component and a high-precision temperature measurement device, connected to a high-performance 8-bit microcontroller. It has a small size, low power consumption, and a signal transmission distance of up to 20 metres, making it suitable for all kinds of applications. It is fully interchangeable and easy to integrate into systems with its standard single-bus interface. The DHT22 is a cost-effective and accurate alternative to expensive imported temperature and humidity sensors, with a measurement range of humidity 0-100%RH and temperature -40~80 Celsius, with an accuracy of +-2%RH for humidity and +-0.5Celsius for temperature. It can be used with a special sensor Arduino expansion board for easy implementation of interactive effects related to temperature and humidity perception. “Full range temperature compensation for accurate relative humidity and temperature measurement
