1. An ice machine comprising:
an ultrasonic bin sensor comprising a lens, the lens configured to face an interior cavity of a storage bin and measure a level of ice sorted inside the storage bin; and
a controller in electrical communication with the ultrasonic bin sensor and configured to control the ultrasonic bin sensor;
wherein the controller is configured to:
filter out a portion of a return signal of the ultrasonic bin sensor below a threshold voltage as part of controlling the level of ice stored inside the storage bin; and
filter out a portion of the return signal exceeding the threshold voltage for a length of time equal to or less than a predetermined time delay as part of controlling the level of ice stored inside the storage bin.
