I am looking for a cigarette smoke sensor and can see that Core Electronics have a bunch of different sensors (MQ-2, MQ-5, MQ-7, MQ-8, etc) but I am not sure which one would be more suitable for detecting cigarette smoke.
I did some research on Google about the composition of gases in the cigarette smoke, but I could not find the percentage of each gas.
I know that it contains Carbon Monoxide, and so I wonder if MQ-7 would be OK to successfully detect cigarette smoke.
This is the sensor:
This sensor would be a small part of an ambitious automated window opener I want to develop for my house. Neighbour from downstairs is all the time smoking weed, so I would like my device to detect smoke (and also rain) and automatically close the window for a given pre-settable time.
The smoke sensor would be placed in the frame of the window and should be quite sensitive.
Thank you all!
