DIY Nitrox Analyzer (Arduino based)

Keep cool guys ! I live in a different time zone on the other side of the pond, and I'm not glued to my computer, ok ?

The link is down below (in French). Helium sensor is not acoustic but thermic.

Looks promising. The MD62 thermal conductivity sensor is used primarily to measure CO2 levels, but I came across a patent for its use with helium.

@JMBL
Do you happen to have a link to the French forum where they spoke about this project? I can read written French, I am interested
Thanks

Nice job. Thanks !

This is great! I already have an analyzer that I'm very happy with, but I'm going to build this because it looks fun.

I believe I have most of what I need on hand, except the sensor.

Thanks for sharing the project!

Test the boost converter before using. The ones I got recently had a holding current of 50 milliamperes. You can use another boost converter running on 2 x AA batteries. Consumption is only 25 milliamperes.

Just wanted to say thanks for posting this. I've used your hardware design as is, and your software as a base - I've added MOD and battery voltage, just for fun.

I've not previously had much contact with Arduino - I've done some PIC assembly stuff a few years ago, but Arduino makes it delightfully straightforward!

I'm glad you found it useful! Maybe you can upload your Sketch.
