SparkFun Humidity and Temperature Sensor Breakout - Si7021

Description

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 I²C 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 I²C communication. This breakout board has built-in 4.7KΩ pull-up resistors for I²C communications. If you’re hooking up multiple I²C devices on the same bus, you may want to disable these resistors.
