Co2 Sensor

#1 Post by JarredAwesome » 01 Nov 2020, 22:36

Hey,

Does anyone know if either a co2 sensor that can read up to 30000ppm.

Or a sensor that can read how much dissolved co2 there is in water?

I know there are versions of the SenseAir S8 that have a range of upto 50'000 ppm.
Not sure how to read that in water though.

You can get the waters co2 level by having a sensor in a "diving bell". But inside the bell it'll be very humid and thus ruining the measurements. If you find a way of removing that humidity you essentially have a PH sensor for the water. Silica gel is possible to use for testing purposes though.

The theory behind the diving bell is that given an time of X, equilibrium will happen in terms of the co2 level in the water and inside the bell.

Oh sorry, it will be measuring co2 in air. My plan is to use Henry’s law to figure out the dissolved

Is that a custom order sensor, or
Can I buy it somewhere?

Is this essentially Henry’s law?

Yep that's Henry's law. And for the S8 for 5% readings i could probably sell it to you. Let me investigate the price for those.

That's the official online shop that me and TD-er are selling hardware through.

I could sell the S8 sensor for 5% on my shop (linked above). Or you can email me on jimmy@grovkillen.com

I got my price confirmed and I could sell it to you for the same price as the regular one: https://firstbyte.shop/products/s8
