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 ...

ESP8266 WiFi gas sensor (Arduino IDE)

Use gas sensor digital output and connect it to ESP8266 GPIO2 pin. Because ESP8266 operates on and gas sensor operates on 5V we will add additional NPN transistor, two resistors and capacitor for voltage level sifter. Don''t forget to add capacitor it helps to set GPIO2 pin high during power on, to boot ESP8266 in correct state.
