UNIVERSAL SELF LEARNING AND ADAPTABLE LEVEL SENSORS FOR RESTROOM DISPENSERS

摘要

Self-calibrating level sensors for dispensers, receptacles and restroom systems. A restroom system includes a first product dispenser for dispensing a first product, a second product dispenser for dispensing a second product, wherein the first product is different than the second product. A first self-calibrating level sensor is located in the first dispenser and includes a housing, a transmitter, a receiver, a processor and memory. The sensor includes logic for causing transmitting and receiving level signals, logic for assigning a first level as an empty level and for assigning a second level as a full level, logic for assigning a third level as the empty level if the third level is less than the first level, and logic for assigning a fourth level as the full level if the forth level is greater than the second level. A second self-calibrating level sensor is located in the second dispenser.
