Crowtail DHT20 - I2C digital temperature and humidity sensor module

Description

The Crowtail DHT20 is designed for measuring ambient temperature and relative humidity in embedded projects, environmental monitoring systems, and educational applications. The integrated DHT20 sensor represents an improved generation compared to earlier solutions, providing lower power consumption, higher measurement accuracy, and enhanced long-term stability.

The sensor uses a fully calibrated digital I2C interface, which ensures fast response time, high immunity to interference, and simplified integration with microcontrollers. No user-side calibration is required, allowing immediate use of the module after connection.

The wide supply voltage range from 2.2 V to 5.5 V enables operation with both 3.3 V and 5 V systems. The Crowtail connector allows quick, solder-free connection to Crowtail base boards, facilitating prototyping of measurement systems, data loggers, and weather stations.
