electrochemical co sensor for household gas alarm

How Do Electrochemical Sensors Work? - Analytical ...

Mar 15, 2021· To put things simply, this sensor type works by means of gas diffusion. Gas finds its way into the outlet of the membrane on top of the sensor housing. Once the gas reaches the working electrode, an electrochemical reaction occurs. This reaction is either an oxidation or a reduction, depending on the type of gas.
