Optimal Analysis and Construction of Computerized Door Controller

Automatic doors use several automated methods to open and close depending on their use and placement. These methods usually require a sensor mechanism on both sides of the door and sometimes include a secondary sensor for safety. Doors with pressure sensor (micro switch) activators have a large pad placed in front of the opening. The pad works like a scale detecting the amount of weight placed on the pad at any given moment. When the pad senses a weight heavy enough to represent a person the door opens. Since the pad also recognizes when a person moves off the pad the same mechanism can hold the door open and close it. Pressure sensors are also used as a safety mechanism such as the ones lining the bottom of certain doors. If the door begins to close on any resistant object the sensors tell the door to open. As a result of enhanced civilization and modernization the human nature demands more comfort to his life. The man seeks ways to do things easily and which saves time. So thus the Automatic Gates are one of the examples that human nature invent to bring comfort and ease in its daily life.
