The Si7021 is a low-cost, easy-to-use, highly accurate, digital humidity and temperature sensor. This sensor is ideal for environmental sensing and data logging and perfect for building a weather stations or humidor control system. All you need are two lines for I 2 C communication, and you'll have relative humidity readings and very accurate temperature readings as a bonus!

There are only four pins that need to be hooked up in order to start using this sensor in a project. One for VCC, one for GND, and two data lines for I 2 C communication. This breakout board has built-in 4.7KΩ pullup resistors for I 2 C communications. If you're hooking up multiple I 2 C devices on the same bus, you may want to disable these resistors.

Note: Full drops of water can damage the sensor. We recommend wrapping the board in Teflon/irrigation tape for extreme conditions where water droplets may find their way onto the sensor.

Dimensions: 0.6" x 0.6"
