MG811 Electrolyte CO2 Sensor Is A Semiconductor Oxide Chemical Sensor That Uses The Principle Of A Solid Electrolyte Battery To Detect CO2
Product description:
MG-811 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.
Sensor characteristics:
MG-811 gas sensor has high sensitivity and good selectivity to CO2,
and is less affected by temperature and humidity changes, and the
sensor signal has good stability and repeatability.
Main application:
Used in air quality control system, fermentation process control
system and greenhouse and other places CO2 concentration detection.
