Product description: Gravity - Temperature and humidity sensor - DHT20 - DFRobot SEN0497
Precise temperature and humidity sensor equipped with DHT20 chip. Factory calibrated, has a connector compatible with the Gravity series. Manufactured by DFRobot, this product is an improved version of the sensor with the DHT11 chip. The output is a digital signal. The sensor's measuring range for temperature is from -40°C to 80°C (with an accuracy of ± 0.5°C), and humidity from 0% to 100% RH (with an accuracy of ± 3% RH).
Product compatible with Arduino and Raspberry Pi
