Abstract
A PCB based electrochemical sensor includes a PCB having a first electrode on a first surface of the PCB, and a second electrode on a second surface. A sensing element, such as a conductive wire, is attached to the first electrode. The PCB includes one or more through holes, and the conductive wire is positioned proximate one or more of the one or more through holes. When the PCB based electrochemical sensor is positioned in a solution to be sensed, the solution fills the through holes. The ions within the solution provide a current pathway between the conductive wire and the second electrode through the through holes. A voltage potential between the two electrodes is measured. The measured voltage potential is used to determine a value associated with the solution, such as a pH value.
