The electrochemical sensor is: will constitute two reactions - work of electrode and electrode electrode and a reference electrodes placed in particular electrolyte, and then in the reaction between electrode voltages, add enough metal catalysts are through the film for measuring gas REDOX reaction, then the circuit by electrolysis gas produced when measuring system, then the current by microprocessor calculate gas concentrations. Electrochemical sensor structure and working principle chart drawing shown below. The first through tiny gas hole and capillary type sensor, and then is disgusting, water barrier to the electrode surface. Through the barrier of gas sensor electrode and diffusion, sensor electrode can react by oxidation mechanism or reduction mechanism. These reactions by targeting gas and design of catalytic electrode materials. The connections between the electrodes, and electrical concentration resistor is proportional to the current will flow in the positive and negativ
