Doors & Gates - Automatic
Automatic doors and gates include all doors and gates which are microprocessor controlled and work automatically. Automatic doors and gates make use of sensors, microprocessors, actuators and hardware converters. When a person comes in front of any such door, usually an infrared sensor makes sense of the person’s presence and sends signal to the microprocessor through A to D converter. Microprocessor in response sends signal to the actuator which opens the door physically.
