The MQ131 ozone gas sensor is capable of sensing ozone air concentration levels between 10ppm and 1000ppm. The ideal sensing condition for the MQ131 is 20°C ±2°C at 65% ±5% humidity. An internal preheater inside the sensor helps achieve the ideal sensing conditions, but the datasheet recommends over 24 hours for preheating to achieve optimal accuracy. Because of the internal preheater ...
Ozone 2 click is an Ozone detection (O 3) sensor, based on the MQ131 gas gas sensor has a sensitive layer made of SnO 2, which changes its resistance when exposed to sensor is able to sense O 3 concentration in the range of 10 ppm to 1000 ppm. The Click board™ is also equipped with a trimmer potentiometer, used to adjust the sensitivity and offset of the MQ131 sensor.
