hi everyone! I am wondering about what methods could be used in order to create a CO2 sensoring system inside a bioprinter.



Hi @DFCH I assume you’re looking to build something you can interact with, rather than looking for an off-the-shelf sensor. This might be a good start:


The sensor itself isn’t cheap, but I guess “cheap” depends upon how important the use is…


Hi @cobnut thanks for you answer. yeah I am looking to build a 3d bioprinter that will be able to regulate CO2 itself, so that the environment is controlled. I will look into that link you sent me!

How do you plan on actually regulating the CO2, in terms of actuators and such? That will play a large impact in what sensor you use for this.
