Enclosure for CO2 sensor

[secantscope]

Hi all,

another day, another sensor request. We're currently looking to buy a CO2 sensor, such as one these for example:

https://www.sensirion.com/en/environmental-sensors/carbon-dioxide-sensors/carbon-dioxide-sensors-co2/

What kind of enclosure would you recommend for this? Is any vented enclosure suitable, or should we look after a specific filter membrane, as picture here:

Thanks in advance!

@secantscope The membrane in the picture looks more than fine for your project, I'd go with it if I were you.

@HectorAllen thanks for your reply. I wish I could go with these enclosures, but these are actual CO2 sensors that I found online. I'm having the hardest time finding the manufacturer of these enclosures...

If anyone knows who builds these enclosures, please let me know.

The money you spend and the effort you put in assembling the system just ain't worth it, in my opinion. You could just get a CO2 detector and end it. My father-in-law installed a Nest and he's satisfied, and I have friends with kids who have directly installed other systems without any hassle. I am looking to get one too, but I'm looking for a cheaper option. I did some research and found a few options within my budget here - https://popular.reviews/smoke-carbon-monoxide-detector/. I hope this helps, good luck with your project if you move on with it though, mate!

Thanks for your reply HectorAllen. For us it is worth the effort because we already have all the other components (power, processing, transmission, cloud, etc...) ready. We're just looking for a low-power sensor that we can add cabled...

I'm gonna ask a few friends, maybe I could share some useful info if that's the case.

Looking forward to their reply!

Keeps surprising me how hard it is to find something that easy. Of course I could simply use any kind of vented enclosure, but these seem less suited for outdoor use...
