DESCRIPTION
The humidity and temperature sensor breakout 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 weather stations or humidor control systems. 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 4.7K√鬩 pullup resistors for I2C communications. If you’re hooking up multiple I2C devices on the same bus, you may want to disable these resistors.
Please Note:
- Full drops of water can damage the sensor.
- It is highly recommended to wrap the board in Teflon/irrigation tape for extreme conditions where water droplets may find their way onto the sensor.
