SparkFun Humidity and Temperature Sensor Breakout - Si7021

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 build 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 pullup resistors for I2C communications. If you’re hooking up multiple I2C devices on the same bus you may want to disable these resistors.Dimensions: 0.6" x 0.6"Documents:SchematicEagle FilesDatasheet (Si7021)Hookup GuideGitHub (Design Files & Example Code)GitHub (Library)
