Gas detection in a room

  1. Jul 20, 2016 #1

    I am not sure if this is the correct forum to post this on, but I guess it can be moved if it is not.

    I just want to know what methods exists to detect gases in a room. Smoke alarms use ionization or electromagnetic light.

    What other technologies exist on the market? What technologies are used in detectors that are used to detect, for instance, radon gas?

    I know light is used to figure out the composition of gases in the atmosphere of distant planets. Is this practical in a room?

    Finally, are there any more theoretical ways of detecting gases? What books should I read to learn about this?

    I think radon gas detectors look for the radiation rather than the gas itself. You can google that and how carbon monoxide detectors work.

    This contains a list of methods used for detecting Radon. If you live in the US, you may qualify for a free or discounted testing kit, depending on your state.

    you also have to account for light or heavy gases when detecting them kind of pointless putting a detector on the ceiling if the gas in question is heavier than air
