Functional Description-
This is a semiconductor sensor for air quality control. Sensitive material of MQ135 gas sensor is SnO2 which with lower conductivity in clean air. When the target combustible gas exist, the sensor conductivity is more higher along with gas concentration rising.
MQ135 gas sensor has a high sensitivity to Ammonia, Sulphide and Benzene steam, also sensitive to smoke (CO, CO2) and other harmful gases. It is with low cost and suitable for different application.
Characteristics-
Good sensitivity to harmful gases in wide range.
High sensitivity to Ammonia.
Long life and low cost.
Simple drive circuit.
Application-
Domestic air pollution detector.
Industrial air pollution detector.
Portable air pollution detector.
