CCS811 and HDC1080 Air Quality Humidity and Temperature Sensor

This module contains a CCS811 digital gas sensor and an HDC1080 humidity and temperature sensor. This sensor module is intended for indoor use in combination with a microcontroller via an I2C interface.

The CCS811 module is a digital gas sensor that uses an integrated metal oxide (MOX) gas sensor to measure "Volatile Organic Compounds" (VOCs) from the air. The sensor can also measure "equivalent CO2" (eCO2).

The HDC1080 module is a humidity sensor with integrated temperature sensor that offers excellent measuring accuracy at very low power. Humidity and temperature sensors are factory calibrated.
