Great progress being made with an interesting blog. Look forward to seeing how the sensor work in practice.

Kind regards

I was reading that Nitrogen Dioxide (NO2) is a respiratory irritant produced when nitrogen in the air combines with oxygen in the burner. Higher concentrations of it can cause asthma. Is your setup going to include Nitrogen Dioxide? Might be one to consider instead of the LPG one (since our range doesn't have propane...).

Great post.

One question. Have you thought about where you are going to put these sensors?

Some of the gases will rise from the burner, but some of them are heavier than air. So sensor placement will be important.

Great write-up and great progress is your project. You really did get quite a crowded breadboard there with all your sensors and support circuits. Keep up the good work!
