MQ4 Gas Sensor Monitor Natural Gas (Methane) leakage ...

MQ series sensors use a small heater inside with an electrochemical sensor in order to measure different kind of gases combinations. They can be calibrated, but, in order to do that a know concentration of the measured gas or gasses is needed for that. For industrial purpose calibrations are done in special metrology laboratories with accurate probes and tests. In our case, we will test it as ...

Presenting MQ sensors: lowcost gas and pollution ...

· Features of the MQ sensors . Most sensors of the MQ series operate with working voltages that are typically at 5V, and have a lower absorption of 1 watt (5V here means less than 200 milliampere); such an absorption is mainly due to the heating element drawing power. As for some MQ sensors, the heater is powered at 2V: a low and atypical voltage, that we might obtain by using a …
