MQ-2/3/4/5/6/7/8/9 SERIES GAS SENSOR MODULE : 
The gas sensor used in MQ-135 gas sensor is tin dioxide (SnO2) with low conductivity in clean air. When there is sensitive gas in the environment where the sensor is located, the conductivity of the sensor increases with the increase of the concentration of combustible gas in the air. There are different resistance values for different concentrations, and a simple circuit can be used to convert the change in conductivity into an output signal corresponding to the gas concentration. The MQ135 sensor has high sensitivity to ammonia, sulfide, and benzene vapors, and is ideal for monitoring smoke and other harmful gases. It is a low-cost sensor suitable for a variety of applications. It can be used as a harmful gas detection device in the home and the environment, and is suitable for the detection of harmful gases such as ammonia, aromatic compounds, sulfides, benzene vapor, smoke and so on. The sensor is specially equipped with M3 fixed mounting hole, using wide voltage LM393 comparator, clean signal, good waveform, strong driving ability, more than 15mA, with adjustable precision potentiometer to adjust sensitivity.
