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 threshold can be set. There is a digital and analogue output via the male pins.
