Get PriceFeatures of The MQ SensorsCoupling to A MicrocontrollerConclusionsMost 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 PWM technique, starting at 5V; in practice we would drive a pulse heater (whose pulse length would be varied), along with a circuit that is based on a PWM modula…See more on open-electronics.orgFuel Tank Pressure Sensor | Cars.com fuel tank pressure sensor is part of the fuel pump assembly and is mounted on top of the tank or inside the tank.
