MG811 CO2 Sensor Features
Good sensitivity and selectivity to CO2
Low humidity and temperature dependency
Long stability and reproducibility
ApplicationAir Quality Control
Ferment Process Control
Room Temperature CO2 concentration Detection
Working PrincipleSensor adopt solid electrolyte cell Principle,It is composed by the following solid cells
Air,Au|NASICON|| carbonate|Au, air,CO2
When the sensor exposed to CO2,the following electrodes reaction occurs
Cathodic reaction2Li + + CO2 + 1/2O2 + 2e - = Li2CO3
Anodic reaction2Na+ + 1/2O2 + 2e- = Na2O
Overall chemical reactionLi2CO3 + 2Na + = Na2O + 2Li + + CO2
The Electromotive forceEMF result from the above electrode reaction, accord with according to Nernsts equation:
EMF = Ec - (R x T) / (2F) ln (P(CO2))
P (CO2)CO2--- partial Pressure EcConstant Volume RGas Constant volume
T Absolute Temperature KFFaraday constant
From Figure 1B, Sensor Heating voltage supplied from other circuit , When its surface temperature is high enough , the sensor equals to a cell, its two sides would output voltage signal ,and its result accord with Nernsts equation. In sensor testing, the impedance of amplifier should be within 1001000GΩ,Its testing current should be control below 1pA.
