MQ-135 Air Quality Gas Sensor usb male to usb female 3v - 5 V SensingThis is an MQ 135 Air Quality Gas Sensor. MQ135 Gas Sensor Module with Digital and Analog Output for Air Quality. The MQ135 gas sensor's sensitive material is SnO2, which has lower conductivity in clean air. When the target combustible gas is present, the sensor conductivity increases as the gas concentration increases. The MQ135 gas sensor is highly sensitive to ammonia, sulphur dioxide, and benzene steam, as well as smoke and other harmful gases. It
