Abstract

A hand sanitizer unit for use with a pump bottle using a user activated dispensing pump with a main body housing an electronic circuit and defining a sensor aperture for use with two passive infrared sensors separated by a mechanical lens baffle to detect movement and direction of the movement. The unit also includes a pump sensor positioned to detect dispensing or lack thereof of a hand sanitizer to sound an alarm when motion is detected and the pump sensor does not detect activation of the user activated dispensing pump. Further items include a mute control switch, communication system, and a direction of motion switch connected to the microprocessor. The programming flow and method of operation of the unit are also disclosed.

Claims

1. A hand sanitizer apparatus for use with a pump bottle using a user activated dispensing pump, the invention comprising:

a main body defining a sensor aperture;

a first infrared sensor positioned to sense movement through the sensor aperture;

a second infrared sensor positioned to sense movement through the sensor aperture;

a mechanical lens baffle positioned between and perpendicular to the first and second infrared sensor;

a microprocessor electrically connected to the first infrared sensor and second infrared sensor;

a pump sensor positioned at the user activated dispensing pump, the pump sensor connected to the microprocessor; and

an alarm connected to the microprocessor, wherein the alarm is sounded when motion is detected and the pump sensor does not detect activation of the user activated dispensing pump.

2. The apparatus of claim 1 further comprising:

a mute control switch connected to the microprocessor.

3. The apparatus of claim 1 further comprising:

communication system connected to the microprocessor.

4. The apparatus of claim 1 further comprising:

a direction of motion switch connected to the microprocessor.
