NuGet package	Not published

The GroveTH02 is a multifunctional sensor that gives you temperature and relative humidity information at the same time with I2C interface. 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.
