MQ-135 Air Quality and Hazardous Gas Sensor
|Detecting Range||100ppm to 1000ppm|
|Operating Voltage||5 V|
|Sensitivity To Gases||Ammonia, Sulphide, Benzene, Alcohol, and Smoke|
The MQ135 Air Quality Gas sensor is used in air quality control equipment and is suitable for detecting or measuring the level of NH3, NOx, Alcohol, Benzene, Smoke, CO2 in the air.
MQ135 gas sensor applies SnO2 which has higher resistance in the clear air as a gas-sensing material. When there is an increase in polluting gases, the resistance of the gas sensor decreases along with that. It can measure the level of polluting gases concentration from 100ppm to 1000ppm.
