Scuba Diving Nitrox Analyser

Nitrox analyser for scuba diving. ESP32-C3 based. Powered by a super capacitor, battery life is only 10 minutes but more than enough for a weekend of use. Using super capacitor instead of lithium battery allows flying in hold luggage. You can use any molex connector oxygen cells, I recommend using retired cells from Diversoft/Kiss/XCCR rebreathers. JJ and AP CCR cell is not supported as they use coaxial connector, it's a easy mod though just extend the length of sensor tube.
