i had ordered the mg811 but found out it sucks because it needs a heating element and to calibrate it correctly, you'll have to have an expensive kit. I am looking into the T6713 co2 sensor, which uses laser technology and has an auto calibration. I looked into the library thats already available and I'll need to familiarize myself with it before I make the purchase.

Thank you, that's a neat little unit.

This language from the datasheet is interesting..

Subjecting sensors to environments less
than 400 ppm for more than 15 minutes may
affect accuracy due to ABC Logic algorithm.

Wonder what that all means.?

the ABC logic algorithm is the auto calibration technology. It's dependent on the fact that the average normal co2 levels outside is 400ppm. So it seems that it uses 400ppm as some short of base case to keep those units regularly calibrated and subjecting it to less than 400(a vacuum) can mess up the ABC logic algorithm.
