Hi all,

I'm looking for smoke detectors that I can integrate into my own development. Until now I have only found complete products on the internet as you can buy them around the corner or detection IC's without actual sensors. I'm looking for small modules or development kits that can also give quantitative values instead of just yes/no signals. I'm open to any measurement mechanism but the regular types seem to use IR-scattering or ionization.

I also consider measuring CO and CO2 concentrations for which I already have ordered some modules.

Any help is appreciated.
