Dual Electrochemical Gas Sensor with Temperature Compensation

Electrochemical sensors work by allowing gas to diffuse into the sensor through a membrane and by interacting with the working electrode (WE). The sensor reference electrode (RE) provides feedback to Amplifier U2-A, which maintains a constant potential with the WE terminal by varying the voltage at the counter electrode (CE). The direction of the current at the WE terminal depends on whether ...

Create Your Own CO Detector - Digi-Key

There are two basic types of electrochemical gas sensors, 2-electrode and 3-electrode. They both operate with the same basic principles. A gas diffuses into the sensor and makes its way to the working electrode. There it reacts with a catalyst and creates ions (charged molecules). Those ions move through the electrolyte (sometimes similar to battery acid) and again react at the counter ...
