MQ131 Ozone Sensor - O3 Detection Module
MQ131 is an ozone gas detection sensor that makes precise measurements. With increasing gas concentration, the conductivity of the sensor is higher. Using Arduino or similar circuit, convert the conductivity change to correspond to the output signal of gas concentration. MQ131 gas sensor has high sensitivity to Ozone, also sensitive to O3 CL2, NO2, etc. PCB size is 32x20mm, total height is 35mm.
MQ-131 Features
- Fast response features
- Mounting holes to facilitate fixed installation
- Probe can plug design for easy testing.
- Signal light indicates output
- Dual signal output (analog output and TTL level output)
- TTL output valid signal low; (low output signal light, accessible from microcontroller IO port)
- Analog output increases with concentration, the higher the voltage, the higher the concentration
- High sensitivity ozone gas (detection concentration range 10PPB-2PPM Ozone)
