How to calibrate a CO2 sensor? - Yoctopuce

01/05/2015· For this, you need to circulate into the sensor either pure nitrogen (N2), or CO2-free air as obtained from a small calibration tool similar to that sold by SenseAir: Zero calibration of the Yocto-CO2. To circulate the gas into the sensor, set a small tip with a external diameter in one of the two openings on top of the sensor, as is the above picture. Circulate the gas at a litre/min speed for …
