Sensors - Gases PRO Sensor Guide - Libelium

Gas sensors (except the combustible gases sensor and the CO2 sensor) are electrochemical cells that operate in the amperometric mode. That is, they generate a current that is linearly proportional to the fractional volume of the target gas. These sensors are composed of 3 metal strips connecting each electrode to the three pins outside of the sensor body and a cell electrolyte. Each electrode ...
