The MQ-131 ozone gas sensor module is a low-cost metal-oxide (SnO₂) based sensor designed for detecting ozone (O₃) in ambient air. It is commonly used for environmental monitoring, ozone generator feedback, and general air quality experiments.
The sensing element operates by changing its electrical resistance when exposed to ozone gas. This change is measured as an analog voltage output through onboard circuitry, which can be interfaced with microcontrollers such as Arduino, ESP32, and Raspberry Pi.
The MQ-131 is sensitive to low-to-moderate ozone concentrations and requires calibration for meaningful quantitative readings. It is best suited for relative measurement and threshold detection rather than precise industrial-grade ozone concentration analysis.
Features:
- Sensitive to ozone (O₃) and other oxidizing gases
- Provides analog output (variable resistance signal) and digital threshold output (TTL)
- Onboard potentiometer for adjusting digital trigger threshold
- LED indicators for power and digital output status
- Compatible with microcontrollers such as Arduino, ESP32, Raspberry Pi, and PLC input systems
- Compact breakout module with mounting holes
- Replaceable MQ-series sensor head design
- Suitable for low-cost environmental and experimental gas detection applications
