alt Hacker Newsif you just want to know if CO2 is too much, 300ppm precision is fine.
I dont need to know the exact level, just give me a green/yellow/red LED and make it cheap so I can have a sensor in every room

No, it's not. You generally want to ventilate an office when you reach 1000ppm, but then the IKEA will often warn you already at 700ppm. 700ppm is fine.
