Hello, everyone!
A client asked me to make a project where he needs to measure:
Current (10A max) AC and DC
Tension (20V max) AC and DC
Water Flow Rate ( 25 L / hour max)
Hydrogen (450mL / min)
Oxygen (1 L / min)
Does anybody know where I cand find the sensors to measure these?
I found the water flow rate meter. What about the rest? Can I measure voltage using the analog arduino port? What about current?
Thanks in advance.
Fernando
We are not a free research group. You have a special tool available on your computer called a search engine. Once you learn how to use that preface each search with the word Arduino example: "Arduino Oxygen flow Sensor"
After you find that draw an annotated schematic and post with your preliminary code, we will help you through it.\
I hope your client does not see this post, that would take away the confidence the client has in you, this is very basic Arduino stuff.
I think the client is looking at a industrial solution of ten thousand dollars and is also looking at AliExpress where modules cost only a few dollars.
Did your client give at least 10 pages of specifications ?
Hydrogen is a small molecule, it can go through things that other gasses can not.
Hydrogen is dangerous because it can collect in the top of a closed space.
Oxygen with a rate of 1 l/min might not seem a lot, but it is extremely dangerous. I'm afraid that you have no idea what you are dealing with.
If you are not qualified to work with those gases, then you should not do this project.
@Delta_G would like this one. Collecting hydroperoxyl radicals?
I try to stay away from anything that's going to get anyone hurt. I try to stay away from anything with a super vague description where the OP can't say what they're actually building. I try to stay away from anything where they're doing something for a "client" unless I'm being put on the pay roll.
I think I'll pass on this one for many reasons. But yes, that is my wheelhouse.
