MG812 Eletrolyte CO2 Sensor

MG-812 is a semiconductor oxide chemical sensor that uses solid electrolyte battery principles to detect CO2. When the sensor is kept at a certain working temperature and placed in a CO2 atmosphere, an electrode reaction occurs between the positive and negative electrodes of the battery, and the output signal voltage is inversely proportional to the logarithm of the CO2 concentration. A voltage change in the test signal can detect a change in the CO2 concentration.
