Dissolved CO2 sensor - Sensors - Arduino Forum

May 06, 2021· Dissolved CO2 sensor. system October 22, 2012, 7:21pm #1. I’m looking to build a sensor for an algae project which reads out the dissolved CO2 content of the algae tanks. This is not easy because the water is opaque and mucky, it’s dissolved, not gaseous CO2, and since the pH is not constant in algae tanks, one cannot use a pH calculation ...
