This small and attractive switch detects motion and a rapid
change in temperture from body heat. As a person moves closer
to it, it switches on or off, unlocking the door from the
inside. This is done quickly and automatically and a person
walking out of a door may not even notice what is happening!
It's wall or ceiling mountable. Often the PIR (passive infrared) switch is the
only type that local fire laws will allow.
Another great way to use this detector is to protect a secure area such a museum exhibition or
painting. A relay output can be connected to an audible signal to warn the museum guards, when
triggered, of a possible vandal or thief.
