The challenge with CO2 monitoring is the sensor, not the electronics. Sensor accurracy and service life are key information.

It is easy to create a low power chemical CO2 sensors with a service life of a few weeks/months. Obviously not pratical for real world applications. So critical data is missing in this press release.

Replacing sensors every few weeks is totally practical for some real-world applications such as life support systems.
