YVOCMK01 Yocto VOC Sensor - GER Electronics

The initial value returned by the sensor is 450 ppm CO2 equivalents (theoretical value for fresh air). The sensor measure relative variations of volatile organic compounds to provide an estimated ppm value, with an automatic baseline correction. The absolute value must therefore be interpreted with great care, as it is subject to drift.

What do you get when you measure CO2 vs VOC

However, in a modern system for demand-controlled ventilation, this is not a problem, the VOC level is simply converted to CO2 equivalent values. So the question is whether we regulate what we should measure, or what we usually measure? If we want a good indoor climate, it is a lot that speaks for VOC as a measure of value!
