Grove HDC1080 I2C Temperature and Humidity Board (HDC1000 / HDC1010 compatible)

The HDC1080 is a HDC1000 compatible temperature and humidity sensor. It is located at I2C address 0x40.

Grove - Temperature and Humidity Sensor (HDC1080) utilizes a HDC1080 sensor, from Texas Instruments. It is a digital humidity sensor with integrated temperature sensor that provides excellent measurement accuracy at very low power. The device measures humidity based on a novel capacitive sensor. The humidity and temperature sensors are factory calibrated. The innovative WLCSP (Wafer Level Chip Scale Package) simplifies board design with the use of an ultra-compact package. The HDC1080 is functional within the full –40°C to +125°C temperature range, and 0-100% RH range.
