ABSTRACT:
A hand washing alert system includes a housing that is mounted on a wall above a doorway. A motion detector is mounted on the housing and is adapted for detecting motion through the doorway. A processor is mounted in the housing and is electrically coupled to the motion detector. A sound emitter is mounted on the housing and is electrically coupled to the processor. An electronic memory storage is mounted in the housing and is electrically coupled to the processor. A message indicating that a person should wash their hands is recorded on the electronic memory storage. The processor is adapted for playing the message on the sound emitter between 20 seconds and 40 seconds after the motion detector detects motion.
