Electro-chemical Sensor
In essence this technology is based on the principle of electrochemical catalytic reaction. As a general rule the sensors respond to the target gases and deliver a very small current signal that is usually proportional to the gas concentration.
Usually, electrochemical sensors are using either a liquid or a gel electrolyte which leads to a couple of challenges during the operation of the sensor.
