Yes that’s what I hear I’m pretty excited to get This co2 monitor to see what’s going on

I think I’ll be able to make a smartphone co2 monitor with a history graph for around 50$ - I want to post the info so everyone can do it. My Vpd monitor only cost 7$ to make And works awesome

did you make this with Arduino?

I am so jealous!
There are 2 things I am jealous about concerning grow room design:
People who can work with Arduino and people who know how to create things with a 3D printer.
