Pyroelectric proximity switches can sense temperature changes with components made of switches called pyroelectric proximity switches. This switch is mounted Pyroelectric detection surface switch LJ30A3-10-J / EJ, when the ambient temperature approaches the different objects LB-M0824LB normally closed output Pyroelectric will change the D- Y7BWSDPC, thus able to detect an object approaching. In practice, this is usually controlled by the permanent magnet is turned on or not two metal sheets, it is also called "magnetron."
