- Wide detecting scope
- Fast response and High sensitivity
- Stable and long life
- Simple drive circuit
They are used in air quality control equipment for buildings/offices, are suitable for detecting of
Resistance value of MQ-135 is difference to various kinds and various concentration gases. So,When using this components, sensitivity adjustment is very necessary. we recommend that you calibrate the detector for 100 ppm NH3 or 50 ppm Alcohol concentration in air and use value of Load resistance that (RL) about 20 KΩ(10 KΩ to 47 KΩ). When accurately measuring, the proper alarm point for the gas detector should be determined after
considering the temperature and humidity influence.
