Precise temperature and humidity sensor equipped with DHT20 chip. The factory-calibrated has a connector compatible with the Gravity series. The product manufactured by DFRobot is an improved version of the sensor with the DHT11 chip. The output is a digital signal. The measuring range of the sensor for temperature is from -40 °C to 80 °C (with an accuracy of ± 0,5 °C), and for humidity from 0% to 100% RH (with an accuracy of ± 3% RH).

Main features:
  • High precision measurement and factory calibration
  • Fast response, high noise immunity
  • Compatible with motherboards powered by a voltage range of 3.3 V to 5.5 V such as Arduino, micro:bit, ESP32, Raspberry Pi
  • The sensor is used in applications such as HVAC, dehumidifier, test and inspection, automatic control, data logger, weather station and many other temperatures and humidity sensing control projects
