With signal output instructions
TTL output signal is low level
Analog 0 ~ 5 v voltage output, the higher the concentration, the higher the voltage
Color is show as pictures.

Air Quality Sensor Module
Size: 32mm X22mm X27mm
Main chip: MQ-135
Working voltage: DC 5v
MQ135 Gas Sensor module for Air Quality having Digital as well as Analog output. 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. MQ135 gas sensor has high sensitivity to Ammonia, Sulphide and Benze steam, also sensitive to smoke and other harmful gases. It is with low cost and suitable for different application.
Used for family, Surrounding environment noxious gas detection device, Apply to ammonia, aromatics, sulfur, benzene vapor, and other harmful gases/smoke, gas detection, tested concentration range: 10 to 1000 ppm.
