Description
The Si7021 is a low-cost, easy-to-use, high-precision digital humidity and temperature sensor. This sensor is ideal for environmental detection and data acquisition and is perfectly suitable for the construction of a weather station or a humidor control system. All you need was two wires for I2C communication, and you have relative humidity measurements and very accurate temperature measurements as a bonus!
There are only four pins that need to be connected to use 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 connect several I2C devices to the same bus, you should deactivate these resistors.
