Low power gas sensor measures air quality

The CCS811 digital gas sensor integrates a metal oxide gas sensor with a microcontroller sub-system and targets indoor air quality monitoring. The 10 lead 2.7 x 4.0 mm LGA packaged device features ease of design, extended battery life, and reduced system cost.

The device uses an I² C interface and can be used for detecting Ethanol (Alcohol), hazardous gases such as carbon monoxide (CO), and a wide range of volatile organic compounds (VOCs), based on its micro-hotplate technology. The chip reduces power consumption through very fast cycle and measurement times, consuming
