MG811 CO2 Carbon Dioxide Sensor Module

Chemical Sensor MG-811 adopts solid electrolyte battery principle to detect carbon dioxide. When the sensor is placed in the CO2 environment, the reaction occurs between the battery positive and negative electrode, and electromotive force is generated between the sensor sensitive electrode and reference electrode. The output voltage signal can be used for carbon dioxide detection.

Features:

Good sensitivity and selectivity to CO2 Low humidity and temperature dependency Long stability and repeatability.

Application:

Air Quality Control,
Ferment Process Control,
Room Temperature CO2 concentration Detection
