Operating Voltage | DC 5 V |
Dimensions | 32mm X22mm X27mm |
Material | PCB |
Usage/Application | Air Quality Monitor |
Detecting Range | 100-1000 ppm |
Model Number | MQ135 |
The MQ 135 Air Quality Detector Sensor Module For Arduino has lower conductivity in clean air. When the target combustible gas exists, the conductivity of the sensor is higher along with the gases concentration rising. Convert change of conductivity to the corresponding output signal of gas concentration. The MQ135 gas sensor has high sensitivity to Ammonia, Sulphide and Benzene steam, also sensitive to smoke and other harmful gase.
