I've got a DIY O2 sensor which works great, but I'd like to get a He and CO sensor in the lineup (ideally with one hookup so gas runs the circuit past all of them).
Does anyone have DIY plans for either type of sensor? I have family members who are electrical engineers, so even a pointer towards circuits which would do the measurement (even if that measurement needs substantial conversion to be useful) would be helpful....
