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 ...
