IoT MQ131 Ozone Gas Sensor Module For Arduino,Raspberry Pi

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 ...

SGX Metal Oxide Gas Sensors –How to use them and how they ...

The basic principle behind the SGX and other metal oxide sensors is that the resistance of the detecting layer in sensor changes in the presence of the target gases. For oxidising gases such as ozone or nitrogen di oxide the resistance will increase; for reducing gases such as carbon monoxide or VOC’s the resistance will go down.

Gas Sensor Metal Oxide from SGX

The basic principle behind the SGX metal oxide sensors is that the resistance of the detecting layer in sensor changes in the presence of the target gases. Or in very simple terms, reducing gases remove some of the ‘insulative’ oxygen species at the grain boundaries thus causing the overall resistance to go down. Alternatively oxidising gases add to the insulative oxygen species causing ...
