Indoor ENS160 Air Quality Sensor with I2C

The DFRobot indoor air quality sensor carries the ScioSense ENS160 in a probe housing with a 1 m cable. The metal oxide (MOX) gas sensor evaluates volatile organic compounds and outputs TVOC, an equivalent CO2 concentration (eCO2) and an air quality index (AQI) via I2C. eCO2 is a value calculated from the VOC and not a direct CO2 measurement. The warm-up time is less than 3 minutes, and an automatic baseline correction keeps the sensor stable in continuous operation. The cable ends in wire end ferrules.

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