MG187 Mini Size Solid Electrolyte CO2 Gas Sensor
Principle Introduction:
MG187 gas sensor is chemical type gas sensor that adopts solid electrolyte cell principle, used to detect carbon dioxide. When sensors are exposed to CO2, battery is positive and negative electrode reaction, the sensor produces electromotive force between sensitive electrode and reference electrode, the output voltage signal can be detected carbon dioxide.
