I need to make a waterproof housing for my air quality sensors

Hi guys,

I'm creating a air quality device that reads the amount of particles from the air, but the device has to be waterproof and still lets air and sound through so the sensors can get their readings. Anybody know a great solution for this big problem?

Thanks in advance for your response!

My thoughts.

You could 3d print a water proof enclosure of your own design for the project. Keep in mind you might have to do some additional water proofing such as gluing it shut to prevent water leakage. Or you could get an otter water proof box that is also crush proof and mod it for the project. Good luck!!!

Thanks for your response,But

Thanks for your response,

But when i make the enclosure waterproof, i won’t have any holes were the air can pass through. So the sensors can pick the right readings of pollutions in the air.

Any solutions for that?

Thanks!!

I think you want splash proof.

Something like Gortex cloth. it blocks liquid water but not air.  you will need to heat the inside of the encloser to keep condensation from building up.

Waterproof

Can you clarify if you foresee it being immersed completely or does it just need to be rain proof? The more details you can provide about your restrictions (and why), the better we can help.

You will need a water proof sensor then.

Sorry but you will have to water proof a sensor and that I don’t know if you can do.

Membrane

Way back in the 60’s when I was in middle school, our science class had a picture on the wall of a box, (like an aquarium), underwater with, I think, a rabbit living in the box. The box was covered with some type of membrane that would let the oxygen molecules through but keep out the larger water molecules.

Now if they were able to do this back in the 60’s, this type of technology must be commonplace today. Google is your friend. Might start out with “artificial gills”.

 

Good luck!

you can put two groups of

you can put two groups of very thin wires near eachother.and connect one to 12v or more dc voltage and the other one to the gnd.when the device goes under the water the water will be electrolysed and will turn into hydrogen and oxygen. make sure those wire groups dont affect your sensor.
