    Abstract: A frost sensor, or a frost/ice/water sensor, and systems and methods of using the same, are provided herein. The frost sensor includes a body including a measurement circuit, and a capacitance sensor including two or more co-planar plates coupled to and extending laterally from the body. The measurement circuit is configured to measure a capacitance sensed by the capacitance sensor, the measurement representing a change of material between the plates over time. The frost sensor also includes at least one mounting component coupled to and extending laterally from the body. In some instances, the frost sensor is coupled to evaporator coils of a cooling system.
