Yeah - the actual sensing element is ~$10 but these modules incorporate a microcontroller that runs a series of algorithms against the sensor output to tune it over time as well as map it to the OSHA CO2 scale. 450 is outside air, 1000 is not great, 2000 you should definitely open a window. We'll see how it goes!
