16/2/2018· 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 ...

Fig2. MQ6 Test Circuit Instructions: The above fig is the basic test circuit of sensor requires two voltage inputs: heater voltage (V H) and circuit voltage(V C). V H is used to supply standard working temperature to the sensor and it can adopt DC or AC power, while V RL is the voltage of load resistance R L which is in series with ...
