Temperature and humidity sensor module with DHT20 sensor, I2C interface, and 3.3 to 5.5 V supply range. Measurement range is -40 to +80 °C and 0 to 100 %RH with typical accuracy of ±0.5 °C and ±3 %RH. More product details

Product Description

The DFRobot Gravity: DHT20 Temperature & Humidity Sensor for Arduino is a temperature and humidity sensor module based on the DHT20 with digital I2C output. The module is designed for 3.3 V to 5.5 V microcontroller systems and connects through the included Gravity-4Pin I2C Sensor Connector.

The DHT20 integrates a dedicated ASIC, a MEMS capacitive humidity sensing element, and a standard on-chip temperature element. According to the manufacturer, the sensor is factory calibrated and designed for low power consumption, stable readings, fast response, and improved resistance to interference. Compared with older basic sensor generations, the module provides a wider temperature and humidity measurement range and outputs data digitally at I2C address 0x38.
