The MQ135 gas sensor module is highly useful for NH3, NOx, alcohol, Benzene, smoke,CO2 detection at home, car or industry. The sensor module can detect NH3, NOx, alcohol, Benzene, smoke,CO2 in the air. It is highly sensitive and responding time is very fast. Depending on the requirements of sensitivity, the sensor can be adjusted with a Potentiometer.

MQ135 is a highly sensitive analogue output sensor which is commonly used as NH3, NOx, alcohol, Benzene, smoke, CO2 gas sensor in MQ sensor series. It is a very popular Gas Sensor in various sectors. The output voltage of the gas sensor increases if the concentration of gas increases. The sensitivity of the sensor is adjustable by the Potentiometer. The MQ135 who is Arduino compatible.

The working voltage of MQ135 gas sensor is 5 volt DC and it draws around 800 mW. This sensor is capable of detecting NH3, NOx, alcohol, Benzene, smoke, CO2 gas concentrations anywhere from 10ppm-300ppm NH3, 10ppm-1000ppm Benzene, 10ppm-300ppm Alcohol.
