Air Quality Sensor Module – MQ135

This air quality sensor sensor module is made using MQ135, a low cost semiconductor sensor which can detect the presence of Ammonia (NH3), Mono-nitrogen oxides (NOx), Alcohol, Benzene, Smoke, Carbon-dioxide (CO2) etc. It has good sensitivity to harmful gases in a wide range. The sensitive material used for this sensor is SnO2, whose conductivity is lower in clean air. It’s conductivity increases as the concentration of sensing gases increases. MQ135 Air Quality Sensor module can be easily interfaced with Microcontrollers, Arduino Boards, Raspberry Pi etc.
