About the influence of temperature and humidity in the ...

In your study, do you realized that the temperature and humidity influence a lot in the concentration values of O3? I did that question, because I am studying this sensor MQ131 (Low Concentration) and seems to me that the temperature and humidity do not influence a lot in the values. Congratulations for your code, it's excellent. ostaquet/Arduino-MQ131-driver. Answer questions ostaquet. It is ...

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 ...
