MQ2 gas/smoke sensor Sensors Arduino Forum

20210506· Hello, new Arduino user here. Having fun so far but I have a question about a sensor called the "MQ2". It is a gas sensor but it is also advertised as a Smoke sensor. Would this mean I could use it as a smoke detector to detect cigarette smoke? I run a small 12 room motel in Michigan where state law prohibits smoking in hotel/motel rooms. I have battery operates smoke detectors in the rooms ...
