Working Principle

The CO2 sensor are very sensitive about CO2 rather than alcohol and CO as they are based on solid electrolyte battery principle. When introduced to a CO2 environment, an electrode reaction happens between both the positive and negative electrode and electromotive force is generated between the sensor sensitive electrode and reference electrode. This reaction makes the output voltage to fluctuate. This fluctuating voltage is used as an alarm to detect CO2.
