Ozone detection using visible light and a custom ...

07/08/2012· We used two methods of ozone detection in this experiment. The first method uses a MQ131 gas sensor which responds to the presence of ozone by changing the resistance within the device. This allowed us to construct a circuit with this ozone detector where we measured voltage to observe the change in ozone concentration. Our second method of ozone detection utilized ozone''s absorption …
