MQ-135 Air Quality Sensor
The MQ-135 Air Quality Sensor is a semiconductor gas sensor designed to detect air pollution and monitor air quality. It is sensitive to gases such as ammonia, nitrogen oxides, alcohol, benzene, smoke, and COâ‚‚-related gases. The sensor changes its internal resistance based on the concentration of gases present, providing analog and digital outputs for monitoring and control applications.
- Sensor Type: Semiconductor Gas Sensor
- Model: MQ-135
- Operating Voltage: 5V DC
- Heating Voltage: 5V (Internal Heater Required)
- Detection Gases: NH₃ (Ammonia), NOx, Alcohol, Benzene, Smoke, CO₂ (Approx. Equivalent)
- Detection Range: ~10 ppm to 1000+ ppm (Varies by Gas)
- Output Type: Analog (AO) and Digital (DO)
