How Does It Work?
The main sensor component of the Ozone 2 click is the MQ131 ozone (O3) gas sensor from Winsen Sensor, which uses the SnO2 (tin-oxide) alloy, which decreases its resistance while exposed to the O3 gas. The greater the O3 concentration is, the more conductive this material becomes. This can be utilized to obtain the O3 concentration readings. The sensor itself contains a small heating element, connected to 5V power supply.
