1. A monitor for augmenting a hand hygiene product dispenser that is mounted to a wall, the monitor comprising:
- a case that is separate from the hand hygiene product dispenser and configured to be mounted to the wall adjacent to the hand hygiene product dispenser;
a sensor that is mounted to the case and that is configured to extend a sensor field from the wall-mounted case to a region adjacent to a product-dispensing nozzle of a hand hygiene product;
processing components that receive communications from the sensor and that determine whether the communications from the sensor indicate use of the hand hygiene product dispenser;
communication components connected to the processing components, the communication components configured to report determined use of the hand hygiene product dispenser to a monitoring system; and
an extension configured to extend from a side of the case and along the wall to which the case and hand hygiene product dispenser are mounted;
wherein the extension comprises a leg that extends away from the wall at a location separate from the case such that the product-dispensing nozzle dispenses hand hygiene products at a location between the leg and the side of the case;
wherein the sensor comprises an infrared transmitter mounted to the leg and an infrared receiver at the side of the case;
wherein the infrared receiver communicates to the processing components when infrared light emitted by the infrared transmitter is reflected to the infrared receiver; and
wherein the processing components determine whether an object is present in the sensor field based on receipt of the infrared light by the infrared receiver.

Abstract
A monitor is located adjacent to a hand hygiene product dispenser and extends a sensor field adjacent to the hand hygiene product dispenser. The sensor senses activity adjacent to the hand hygiene product dispenser in the sensor field. The monitor determines whether sensed activity indicates a use of the hand hygiene product dispenser and reports a use of the dispenser to a monitoring system when a use is determined.
