This is the Black variant of the MQ-131 Ozone Gas Detector Sensor Module WITH BLACK CAP in Gas and Dust Sensor. Available at ₹1,434.88 (₹1,216.00 + GST) with free shipping across India.
MQ-131 Ozone Gas Detector Sensor Module
The MQ-131 gas sensor uses O3 SnO2 as its sensitive material, which has lower conductivity in clean air. When ozone gas is present, the sensor’s conductivity increases with the rising gas concentration. A simple electric circuit can convert the change of conductivity into a corresponding output signal of gas concentration. The MQ-131 gas sensor is highly sensitive to ozone, and also responds to O3 CL2, NO2, and other gases.
Features:
- Fast response characteristics
- Mounting holes to facilitate fixed installation
- The probe can plug design for easy testing.
- Signal light indicates the output
- Dual signal output (analog output, and TTL-level output)
- TTL output valid signal is low; (low output signal light, can be accessed by the microcontroller IO port)
- Analog output increases with the concentration, the higher the voltage the higher the concentration
- The ozone gas with high sensitivity (detection concentration range 10PPB-2PPM Ozone)
- Long life and reliable stability

Applications & Use Cases
The MQ-131 Ozone Gas Detector Sensor Module WITH BLACK CAP is a versatile gas and dust sensor used across a wide range of applications including air quality monitoring, gas leak detection, industrial safety, HVAC systems, and environmental monitoring.
Common use cases:
- Building a gas leak alarm for LPG/methane
- Monitoring indoor air quality (CO2, VOC)
- Dust monitoring in a workshop
This product is ideal for environmental engineers, safety professionals, and IoT developers.
Technical Tip: MQ-series sensors need a warm-up period (24-48 hours for first use). Calibrate in clean air for accurate readings.
