Arduino-MQ131-driver

The MQ131 is a semiconductor gas sensor composed by a heater circuit and a sensor circuit. Heater consumes at least 150 mA. So, don't connect it directly on a pin of the Arduino. Sensor MQ131 requires minimum 48h preheat time before giving consistent results (also called "burn-in" time) There are two different MQ131; a black bakelite sensor for low concentration of ozone and a metal sensor for ...
