How Do Automatic Doors Work?

You have likely noticed that your local grocery store has automatic entrance doors. These are a common type of commercial entrance doors, and are very popular in industrial or commercial settings.

Automatic opening doors are doors that open automatically when someone approaches, rather than opening manually using a door handle or bar. These doors are common in settings where people passing through would have their hands full, or would have a difficult time opening the door themselves. These doors have also proven a real boon to people with physical disabilities, as they ensure disabled access to public facilities. In hospitals and medical labs, automatic opening doors are very important, because they ensure that doors are kept closed at all times, which reduces the risk of cross-contamination.

Automatic door systems can be powered open and closed either by electricity, spring, or both. The automatic opening doors are triggered when a sensor detects traffic is approaching. The sensor can either be a pressure sensor under the floor mat, an infared beam shining invisible light that will trigger the automatic sliding glass door when the beam of light is broken, a motion sensor, or a remote sensor.

Automatic doors may not be a technology you spend very much time thinking about, but such a simple thing has made your life so much easier. Consider that the next time you breeze out of the grocery store with a cart full of groceries, instead of having to try to juggle several bags of groceries while trying to open the door.
