Healthy Sensing: Do you know when your proximity sensor is sick?

A proximity sensor is a sensor capable of detecting the presence of nearby metal objects without any physical contact. The proximity sensor generally functions by detecting changes in a local electromagnetic field. This field could be emitted by the proximity sensor itself, or by the metal target (magnet) being detected. When a metal object is detected by the sensor, the output of the sensor changes state.
