Since i am hell bent on using Hydrogen pretty much for anything,and since i am almost close to make my own hydrogen generator with separated gasses and its own electricity generator,i saw that arduino has smoke & gas detector which include hydrogen i was wondering if there is a way to make work arduino for the specific use of hydrogen purity testing.
Specifying that i have no clue on how hydrogen purity tester works.
Asking because i saw that for sale there are hydrogen purity tester.

"Underlining i am almost ignorant on electronic and coding,also i believe that pushing forward and very hard on changing people minds about hydrogen and its uses that for sure will benefit mainly the planet and make so that oil extracted from the planet its reduced drastically or even zeroed.
Do please avoid comments like hydrogen is a dangerous gas,i point out that hydrogen is dangerous a bit more than other gasses only because you cannot smell it".
Your topic was Moved to it's current location / section as it is more suitable.
Could you also take a few moments to Learn How To Use The Forum.

It will help you get the best out of the forum in the future.

Many explosive gasses have no smell, such as methane. The smell you associate with methane is an extra chemical added to the gas to allow us to smell it for safety reasons. I guess the same could be done for hydrogen.
Before we get too far, please tell us the pressure of the hydrogen you are going to create.

H2 can get out of places that other gases can't, or can't get out of as fast.
That makes it differently dangerous.
Was I not supposed to say that?

Of course you can say that! It is the very best way to purify hydrogen. Pure hydrogen is pretty much inert. Whe mixed with O2, look out!

Most of the CHEAPER sensors use a heating element to sniff various gasses and must almost always be calibrated at regular intervals or the system itself must be capable of performing self tests in known atmospheres / gasses.
So please be both aware and wary of whatever sensor you choose to try.

I really think you must correct this before you continue...
"Specifying that i have no clue on how hydrogen purity tester works"
Let me give you some historical perspective.
I once bought a nitrogen generation system for our selective soldering system. The purity wa supposed to be 99.999% pure N2. The internal monitoring system used a O2, oxygen, sensor to measure the O2 in the gas being produced, then subtracted that value from 100%. The trace gases are too small to be counted, The melted solder only reacted to O2. All H2O had already been eliminated from the feed air. So to measure the H2 concentration, you need to measure the other gas concentrations and subtract from 100%.
Another example was a customer that tried to quantify the H in commercial power transformers. Hydrogen is produced over time when the cooling oil is heated. Excessive H means the transformer must be taken off-line and the oil replaced. Too much H and too much heat will result in a very entertaining explosion.
The company worked for years to develop a usable H sensor. We mad made many, many circuit board for them. The company eventually moved and later disappeared without ever succeeding in a sensor.
Other customers tried to develop H fuel cells based on decomposition of alcohol. They are still trying. I don;t think they ever had a successful H quality sensor.
Good luck to the OP.
Paul
I work a lot on the decomposition of alcohol.
It's enormous fun.

I don't know and the Arduino forum probably isn't the best place to ask... 
Give us a link to the sensor and we can probably tell you how to link it to an Arduino.

Of course, the easiest way to get hydrogen "at home" is with electrolysis and the supply is unlimited, but then you're not generating energy you're just converting and storing it.
I didn't know how it's commercially produced but a quick Google pointed me to Wikipedia:
As of 2020, the majority of hydrogen (∼95%) is produced from fossil fuels
Pretty funny, eh? 
So you can buy a Hydrogen powered Honda and you're burning fossil-fuels, or you can buy a Tesla and use electricity (possibly) generated from coal or other fossil fuel!
Yes, there is a finite amount of oil and in the 1970s we were "running out of oil" and there were shortages but currently there's probably more available than ever before! At some point other sources of energy will become more economical. Hydro is probably cheaper now but it can't grow without building more dams and that "damages the environment". Currently solar is only "cheaper" when subsidized.
Petroleum will run out when plate tectonics cease to exist.

...but I seem to remember hearing we're currently getting through about three million years of production, every year.
OP: do post a link to whatever sensor you have in mind. I take your word for it that you know how to deal with hydrogen safely. The fire hazard is just one of many issues... the storage of hydrogen, in high pressures, is a major problem in itself, as hydrogen is very good at destroying metals.
DVDdoug:

Now if only the true price for fossil fuels would be charged... that includes the long term cost to the environment (global warming, soil/water pollution) and short term human health (soil/water/air pollution)! Then solar would suddenly be really cheap, and wind even cheaper.
Over the past decades we have seen fuel shortages due to too many refineries being offline - many of those are old, and they're hardly being replaced. Oil companies aren't stupid. They know it's not worth building new ones, let alone expand capacity.
Now if only there were a good way of storing large quantities of (electric) energy...
Hi
Is this project associated with this thread?
https://forum.arduino.cc/index.php?topic=724640.msg4872220#msg4872220
Can you please draw a basic diagram of what you want to do?
I understand you are aiming to make a H2 generator, but your method of generating it is very confusing.
Have you researched anything about measuring hydrogen concentration.
Can you please tell us your electronics, programming, arduino, hardware experience?
Thanks.. Tom...

Hi and thank you all for the answer,many have missed the POINT!.
What i am asking is: CAN ARDUINO BE USED AS HYDROGEN PURITY TESTER YES? NO?
IF YES WHERE CAN I FIND THE CODE AND WHICH ARE THE COMPONETS NEEDED?.
The project you mentioned Arduino Working as an AVR "Automatic Voltage Regulator" - Motors, Mechanics, Power and CNC - Arduino Forum its a part of the complete assembly.
Just an Arduino: of course not.
An Arduino with an appropriate sensor: most likely yes.
You tell us which exact sensor you want to use: you know the exact parameters it has to perform: work at what pressure, at what temperature, with what impurities you expect (a sensor for those impurities may indeed be a much better approach than a sensor for the hydrogen itself), what accuracy is acceptable, etc.
When you post the details of that sensor including its datasheet we will most likely be able to tell you if it can, and if yes how to, be interfaced with an Arduino.
The problem here is of course that you still have not posted any information of sensors that caught your attention, nor any of the parameters the sensor has to work with.
I just read your other thread as well, and I think you have to really do a little bit more research on what an Arduino actually is. That would take away a lot of the magic, I know, but it would put you also a bit more firm into reality.
An Arduino is a microcontroller. It can control stuff. It can read a sensor. It can control a motor though a motor controller. All that kind of things. All an Arduino can really do is read inputs and produce outputs based on it. You have to provide the hardware that produces the inputs. You have to provide the hardware that takes the outputs. Without that external hardware an Arduino board can do little more than blink its built-in LED. Of course that's pretty, but it's not doing much in the way of real work.
Hi,
Have you looked for suitable sensors for a start.
Most sensors have analog voltage, current, digital of some sort or RS232 type outputs.

I've checked on the shop and specifically FOR HYDOGEN i saw only the detector sensor which includes hydrogen gas along with smoke and other gasses.any of you know if there is a specific sensor that can suit my project?.
REMINDER:Arduino working as Hydrogen Purity Tester.
If there isn't a code for arduino nor the specific component to make work arduino as hydrogen purity tester well that topic can be closed coz it won't be of ANY USE FOR ME!.
Regards Ludo
Thinks: I'm looking for an esoteric sensor for a dangerous gas.
Do I ask where I can find one in;
A) an industrial chemistry forum, or
B) a forum for hobby microcontrollers.
Oooo. That's a tough one.
