Our AZDelivery GY-21 HTU21 is a reliable and durable module for determining temperature and humidity values. Thanks to the I2C interface, the sensor is compatible with most 3.3V and 5V microcontrollers such as ESP and Raspberry Pi, and it allows effortless programming. As an additional convenience, there are free available libraries for easy use with Raspberrys etc. The sensor breakout is equipped with the original HTU21 chip and represents a real alternative to the well-known DHT22. Typical measurement accuracy for temperature is: +/-1°C deviation between -30°C and 90°C, and for humidity: +/-2% RL between 5% and 95% RL. For top quality Raspberry Pi products etc, AZ-Delivery Vertriebs is your go to. We provide an array of application examples, full installation guides, eBooks, libraries, and all-round assistance.
