sells a kit for air quality monitoring mfg by
formatting link
it uses a heated sensor of some kind, shown as a capacitance symbol on the schematic.
anyone know the principle behind the sensor used in this kit?
they claim (iirc iianm) that it will detect carbon monoxide as well as particulates, does this sound reasonable / likely?
otherwise, any recommendations out there for a CO sensor able to pick up small CO leaks into an automobile passenger area?
tia!
