Good to put it on the floor next to the filter or sump to check for leaks... It takes digital input signal.

CO2 gas is composed of different types of atoms have absorption spectrum in infrared range. Absorption intensity abides by Lamber-Beer’s Law

CM1101 series adopts advanced non-dispersive infrared technology (NDIR) , which can be integrated in safety and alarming devices, able to be used for CO2 concentration detecting, air quality monitoring, HVAC, buildings, schools, medical, air conditioning, environmental monitoring, mushroom farming, fireplace ,CO2 controller etc .

Anyone has bought a similar one for indoor air quality monitor ?

I took 2 readings on a small canister filter with no medium.

The sensor does limit output but only by 5-11%. While the filter was running, the arduino read anywhere from 9-12L/minute. It varies I'm not sure why; maybe that's how filters run but I'd have to account for margin of error on the sensor and my errors. It might be better if I took multiple readings and average them out instead of take a calculation ever second.

It's fairly accurate with actual numbers being 11.13 l/m, and 10.97 l/m. I used my iPhone as the stop watch.

price around $16.

You can get them on ebay as well. It could be use to alert low CO2 when place inline.
Some arduino code that might help.

Cost: $28

The benefit of being brushless is it can run for a long time without wearing out.

This looks great compared to the other products currently available. You can draw your own IC.
Resistance is only 20 ohms.
