Upgrading a Chinese Diesel Heater with a Lambda/Oxygen sensor -- Part 1

The Chinese Diesel heater already runs without a piston pump. Check out my previous videos about that: https://www.youtube.com/playlist?list=PLzcdZAK3KLyaJuwlMOtztpK-GKtdsU56G The next step will be to add a Lamda/Oxygen sensor to the Arduino controller to have the fan controlled so it always delivers the correct amount of air for the cumbustion. If I get this working, the heater will also be independent of any elevation changes and can also run in extreme elevations.
