Electrochemical Sensor - an overview | ScienceDirect Topics

In electrochemical sensors the target gas interacts with an electrolyte causing electrochemical reactions which produce a current. This current is dependent upon the concentration of the target gas (by either a linear or logarithmic relationship) and can be measured. Currently in-use models of electrochemical sensor include the Alphasense D-4 mini and the OMC-1108. In comparison to the …

2018-07-22· A nitrogen dioxide (NO 2) sensor would only detect NO 2 and a carbon monoxide (CO) sensor would only detect CO and so on. While electrochemical sensors are designed to be as specific as possible, most will respond in some manner to gasses other than the target gas. This is called “cross-sensitivity” and is a result of the interfering gas also reacting on the sensor electrode.
