MQ-135 Air Quality Detector Sensor Module

MQ-135 Air Quality Detector 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.

Features :

• Sensitivity to Ammonia, Sulphide and Benzene steam
• With signal output instructions
• The TTL output signal is low level
• Analog 0 ~ 5 v voltage output, the higher the concentration, the higher the voltage
• Color is showing pictures.
• Sensitive for benzene, alcohol, smoke
• Fast response and recovery
• Adjustable sensitivity
• Signal output indicator
• Output voltage boosts along with the concentration of the measured gases increases.
