Hi, I'm designing a breathalyzer using MQ303A sensor.
Accourding to the datasheet the sensor needs a warm up time of several minuties when supplied with 0.9V, however when designing a breathalyzer that's not a great idea.
So in the datasheet it is mentioned that i can supply the sensor with 2.2±0.2V high voltage for 5-10secs which would make it stable, i'm assuming then i can bring it down to the normal value of 0.9V
So does anyone know how to do that? To feed the sensor with 2.2±0.2V for a certain time and then reduce it back to 0.9 V ?
here is the datasheet of the sensor
