This is a multifunctional sensor that gives you temperature and relative humidity information at the same time. It utilizes a TH02 sensor that can meet measurement needs of general purposes. It provides reliable readings when environment humidity condition in between 0-80% RH, and temperature condition in between 0-70°C, covering needs in most home and daily applications that don't contain extreme conditions.
This demo is going to show you how to read temperature and humidity information from this Grove - Temperature&Humidity Sensor (High-Accuracy &Mini) Sensor.
The Temperature and Humidity sensor is connecting to analog port I2C of Grove - Base Shield.
