This sensor detects a number of gases so that the air quality in general can be measured.
The MQ-135 can record gas concentrations from 300 to 5000ppm.
The sensor has both an analog and a digital output.
The digital output gives a high signal when the gas concentration exceeds a certain threshold value (adjustable by means of the potentiometer).
