Gravity ENS160 IAQ Air Quality Sensor Module

The DFRobot Gravity air quality module carries the ScioSense ENS160, a metal oxide (MOX) gas sensor for indoor air. The chip evaluates volatile organic compounds and outputs TVOC, an equivalent CO2 concentration (eCO2) and an air quality index (AQI). eCO2 is a value calculated from the VOC and not a direct CO2 measurement. After a warm-up time of less than 3 minutes the sensor provides usable values, and an automatic baseline correction keeps it stable in continuous operation. The I2C address is selected with a switch.

Recommended alternative for a true CO2 measurement (NDIR): Gravity I2C SCD41 Infrared CO2 Sensor

Note: The connection cable can be converted to male pins with a Dupont cable M-M, so that it also fits an Arduino UNO.
