MQ135 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 sensors conductivity is more higher along with the gas concentration rising. Please use simple electrocircuit, Convert change of conductivity to correspond output signal of gas concentration.
MQ135 gas sensor has high sensitity to Ammonia, Sulfide and Benze steam, also sensitive to smoke and other harmful gases. It is with low cost and suitable for different application.
Character Configuration
* Good sensitivity to Harmful gases in wide range
* High sensitivity to Ammonia, Sulfide and Benze
* Long life and low cost
* Simple drive circuit
Application
* Domestic air pollution detector
* Industrial air pollution detector
* Portable air pollution detector
