Abstract

This study focuses on the development of the Electrochemical type $CO_2$ sensor Module by using solid electrolyte which was first developed in our country. The module applied the creative fundamentals that the voltage state generated from Electro-chemical reaction using new materials is converted into $CO_2$ ppm. The study verified the accurate of Electromotive Force(EMF) through the experiment using high-impedance opamp(INA332) to measure EMF which ranges from 100mV to 600mV to be outputted from $CO_2$ sensor, and the small electric current of some nano-ampere(nA)
