· For starters, it can measure CO 2, temperature, and humidity. That makes it more of an ‘environment monitor’ than just a particle monitor. If you have indoor sources of air pollution (VOCs) like new furniture or remodeling, high CO2 levels can mean that those indoor pollutants are building up. However, at 1,480RMB (over $200) it’s not cheap.

CO2 Sensor Measurement Range, Accuracy and Precision ...

NDIR CO2 sensors take a new reading anywhere from 20 times a second to once every 30 seconds. As each reading is taken the sensor's on-board software takes into account all the previous measurements and report the average. This solves the problem of precision. If you want a more precise CO2 reading, look for a sensor with a higher frequency of measurements. Assuming the sensor is properly ...
