DFRobot Gravity ENS160 Air Quality Sensor – TVOC / eCO2

The DFRobot Gravity ENS160 Air Quality Sensor is an indoor air monitoring module based on the ScioSense ENS160 sensor chip. It measures TVOC, eCO2, and AQI values using advanced MOX sensing technology with TrueVOC™ processing for improved accuracy and fast response. The sensor features intelligent on-chip algorithms and automatic baseline correction to ensure long-term measurement stability. Operating from 3.3–5.5V with an I2C interface, it integrates easily into embedded systems and is suitable for smart home devices, HVAC control, and environmental monitoring applications.
