DIY CO2 Meter

[haley-pi]

Hey Guys,

I am working on a project that can measure how much dissolved co2 is in my aquarium. I have overcome a few of the major obstacles, but I have hit a bit of a wall.

Has anyone done this? I am using henry's law to figure it out, if that means anything to anyone here.

My current problem is I can't find a co2 sensor that can read upto 30,000 ppm in the air. Anyone know where I can find this?
