GY-21 HTU21 SHT21 Digital Humidity And Temperature Sensor Module

The GY-21 HTU21 Sensor Module is a low-cost, easy-to-use, high-accuracy digital humidity, and temperature sensor. This sensor is ideal for environmental sensing and data logging and perfect for weather stations or humidor control systems. All you need is two lines for I2C communication and you’ll have relative humidity and very accurate temperature readings as a bonus!

There are only four pins that need to be connected to start using this sensor in a project. One for VCC, one for GND, and two data lines for I2C communication. This breakout board has built-in 4.7k pull-up resistors for I2C communication. If you’re connecting multiple I2C devices on the same bus, you may want to turn off these resistors.
