This logger sensor is based on an electromechanical reaction between CO₂ gas and the sensor.

The result of the electromechanical reaction is voltage, measured by the logger sensor. The measure units are ppm (parts of CO₂ per million of air).

Note: The sensor must be calibrated before every use according to the following simple procedure: connect the sensor to the PC through a USB module or a battery module. Wait for about 15 minutes to warm the sensor and press the pushbutton switch on the CO₂ logger sensor for 3 seconds. Preferably this calibration should be performed in open space. A bottle adapted to the sensor is supplied.

Experiment Duration: 1 second to 31 days.
