The DHT20 is a factory-calibrated digital humidity and temperature sensor with an I²C interface. An upgrade to the popular DHT11/DHT22 series, it provides reliable environmental measurements without requiring additional calibration or external components.

Key Features

• I²C Digital Output – Standard I²C interface (address 0x38) for easy microcontroller integration
• Factory Calibrated – Ready to use out of the box, no additional calibration needed
• Humidity and Temperature – Measures both relative humidity and temperature
• Low Power – Suitable for battery-powered and remote sensing applications
