MQ-135 Gas Sensor Module 6W It also contains a USBMQ135 gas sensor module for air quality with digital and analog output. The sensitive material of the MQ135 gas sensor is SnO2, which has a lower conductivity in clean air. When the target combustible gas is present, the conductivity of the sensors increases as the concentration of the gas increases. The MQ135 gas sensor is very sensitive to ammonia and benzene vapors, as well as smoke and other harmful gases. It is affordable and suitable for various
