Presenting MQ sensors: lowcost 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 ...

Using the MQ136 Sensor Sensors Arduino Forum

May 06, 2021· I just received a SainSmart MQ136 Semiconductor Sensor for Hydrogen Sulfide, which is a sensor attached to a little board. This is different from a lot of the gas sensors I''ve seen online that don''t come with the board. I''m not exactly what this is called and what purpose it serves, but I guess it contains things to make it easier to use. It also has a potentiometer on the back, but since I ...
