2021-05-06· Greetings! I have built an exact replica of the MQ2 Smoke Sensor Breadboard setup from Derek Erb’s post on the forum: Here’s where my problem lies: The values on my serial monitor are consistent, around 659 or so (assuming on analog scale of 0 to 1023) even when there is NO smoke in the room. It would put it on a scale of 60% smoke density in the air…which definitely is NOT the case ...
