An electrochemical sensor is provided that includes a housing having an outer wall, a plurality of longitudinal walls disposed within the outer wall, and a reference chamber housing a reference electrode. In accordance with the disclosure, the controller provides a controlling mechanism, such as a control algorithm, that will provide the necessary power to operate the one or more solenoids throughout the range of battery voltage in a manner that optimizes the voltage discharge from the battery and simultaneously maximizes battery life. The user is presented with the ability to traverse a two- or three-dimensional geographic terrain. Accordingly, even by setting the heating capacity of the interior heat exchanger at a maximum degree, it can restrict a windshield from being fogged in the defogging mode. In various implementations, a switch is used to select one of a plurality of LED lights, in which one light is of a color, such as red, which is suitable for preserving night vision.
