MQ131 ozone sensor -

This breakout for the MQ131 sensor responds to the presence of ozone in the air. As the ozone concentration increases, the resistance changes and the ozone concentration can be measured by measuring the analogue output voltage. The sensor is of good precision and is normally used in ozone concentration detectors. There is a 3362 potentiometer on the board with which the digital signal ...

· The correlation of the humidity and the resistance ratio is very badly explained in the graph. I hope you can make something good out of that. I hope you can make something good out of that. I believe that with the measurements you are making, the results should be near to exact even without the temperature measurement since the test conditions were 20°C and 55% RH.
