Product Description:
MG812 Low Power CO2 Semiconductor Oxide Chemical Sensor
Features:
MG-812 is a semiconductor oxide chemical sensor that uses solid electrolyte battery principle to detect CO2. When the sensor is kept at a certain operating temperature and placed in a CO2 atmosphere, the positive and negative electrodes of the battery will react, and the electromotive force will be generated between the sensor's sensitive electrode and the reference electrode. The output signal voltage is inversely proportional to the logarithm of CO2 concentration, and the change of CO2 concentration can be detected by testing the change of signal voltage.
It is used in air quality control system, fermentation process control system, greenhouse and other places for CO2 concentration detection
