Yoctopuce has been offering a CO2 sensor for some time now. The current model, the Yocto-C02-V2, has a measure range of 0-40000ppm, or 0-4%. This is sufficient for most common applications.

At Yoctopuce, we even have several that we use every day to monitor various experiments. But when we stumbled across SeeedStudio's reTerminal, we were keen to test it out to see if it could be used as an alternative.
