The output is ppmv. It's pretty convenient. All the info is in the datasheet.

The sensor is sent out calibrated to atmospheric CO2 at 400ppmv or something like that.... They also suggest to use Nitrogen and that should give me a 0ppm... I'm not looking for absolute values so what came out of the factory to me is fine.
