Electrochemical Sensors:
Electrochemical sensor apply gas detection with excellent sensitivity, selectivity and low power consumption. Electrochemical sensors work by performing an electrochemical reaction at the interface between an electrode and a gas. In the case of carbon dioxide detection, the electrochemical sensor usually consists of a working electrode, a reference electrode and an electrolyte. When exposed to carbon dioxide, a chemical reaction occurs on the electrode surface, producing an electrical signal that can be measured and quantified to determine carbon dioxide concentrations.
