About the Product
Descriptions:
The MQ-135 Air Quality Gas Sensor is a versatile air quality sensor that can detect a wide range of gases commonly found in polluted air. It utilizes a tin dioxide (SnO2) semiconductor material whose conductivity changes depending on the concentration of various gases in the surrounding atmosphere. This change in conductivity is converted into an analog voltage output, which increases with higher gas concentrations. The MQ135 is often used in air quality monitoring equipment for detecting harmful gases and smoke.
Features:
- Wide Detection Scope: Sensitive to a variety of air pollutants, including ammonia (NH3), benzene (C6H6), toluene (C7H8), alcohol, smoke, carbon dioxide (CO2), nitrogen oxides (NOx), and sulfide (S)
- High Sensitivity and Fast Response
- Stable and Long Lifespan
- Low-Cost and Simple Drive Circuit
