Abstract
A proximity detector includes a sensor providing a proximity reading. The proximity detector is capable of comparing the reading to a rising threshold level and a falling threshold level, wherein the falling threshold level is less than the rising threshold level. The proximity detector continuously stores a minimum reading value for the proximity reading. The proximity detector will report the presence of granular material only if the proximity reading remains less than the falling threshold level and within an epsilon value of the minimum reading value for a predetermined period of time.
