Product Description:
MG812 Low Power CO2 Semiconductor Gas Sensor For CO2 Concentration Detection In Air Quality Control Systems
Features:
MG-812 is a semiconductor oxide chemical sensor that uses the principle of a solid electrolyte battery to detect CO2. When the sensor is kept at a certain operating temperature and placed in a CO2 atmosphere, electrode reaction occurs in the positive and negative electrodes of the battery, electromotive force is generated between the sensor sensitive electrode and the reference electrode, and the output signal voltage is inversely proportional to the logarithmic linear relationship of CO2 concentration, and the change of CO2 concentration can be detected by testing the change of signal voltage.
