The MQ-131 is a low concentration Ozone gas sensor from Winsen. The sensing material for the MQ-131 is WO₃. It will have lower conductivity in clean air and higher conductivity when the ozone concentration rises. This sensor has high sensitivity to ozone, and also has sensitivity to strong oxide such as Cl₂, NO₂ &etc. It responses oppositely to organic interference gases. The sensing range is 10 - 1000ppm. A simple circuit makes measuring this change in conductivity and turning it into data fairly straight-forward, but does require some calibration.

Note: PCB is not included.
