DHT22- digital sensor for detecting the temperature and humidity in the environment. Unlike his predecessor DHT11, it has a high level of measuring accuracy and can be used on the street. 

  • The output of a digital composite signal from the temperature and humidity sensor has previously been calibrated.
  • It's dedicated digital module acquisition technology and temperature and humidity sensing technology,
  • Ensure that the product has very high reliability and excellent long-term stability.
  • Includes capacitive moisture sensor component and high precision temperature measuring element,
  • A high-performance 8 bitrate mini controller is connected.
  • So the product has the excellent quality, ultra-fast response, strong anti-interference ability, extremely high price-performance ratio.
  • Each sensor has a very accurate moisture calibration.
  • Calibration factor in the form of a program stored in a microcontroller, and the sensor inside the detection process signal processing to call the calibration parameter.
  • One standard bus interface, makes system integration becomes simple and fast.
  • Super small size, low power consumption, the signal transmission distance of 20 meters,
  • Products for 3 valves (one bus interface) convenient connection.
