How Do Store Door Sensors Work

These garage door sensors work when electricity is transformed into an infrared beam of light.

How do store door sensors work. It sends the beam of light to a receiving unit on the other side of the garage door. Sensors are connected to an electronic drive train which is attached to the panels of the door through an auxiliary drive or cog wheel. This light is emitted from one side of your garage door from a sending unit that sits 4 inches up from the floor. There are two ways to detect a garage door opening.

These sensors are much like the motion detectors that open the doors to the grocery store or cause the sinks and toilets in the airport to activate without touch. It s surprisingly easy to do even when you ve paid for your item and had it deactivated at the checkout. When the garage door is raised it breaks the circuit and sets off the alarm. But how do they work.

Door sensors have one reed switch and one magnet creating a closed circuit. H ow many times have you walked through a store s doors and to your extreme embarrassment set off the anti theft alarm. Anti shoplifting alarms use a technology called rf radio frequency while a similar but more advanced technology called rfid radio frequency identification. There are two basic types of motion detecting systems.

With a standard door sensor or with a pitch sensor. The auxiliary drive is connected by rubber belts that regulate the opening and closing motions of the doors. We see motion sensing devices everywhere. The standard sensor works the same as on any other door.

If someone opens an armed door or window the magnet is pulled away from the switch which breaks the circuit and triggers an event. There are those with active sensors and those with passive sensors.
