Presenting MQ sensors: low-cost gas and pollution ...

Feb 16, 2018· 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 ...
