Interface BME680 Environmental Sensor with Arduino | The ...

· BME680 as IAQ (Indoor Air Quality) Sensor. The BME680 is a metal oxide-based sensor that detects VOS by absorbing its sensitive layer. BME680 reacts with most volatile compounds to pollute indoor air (except CO2). The VOC in the air around the BME680 can measure the sum of contaminants, such as and high VOC levels because of gassing out of paint, furniture, or garbage, cooking, food ...
