Abstract
Opening and closing of doors have always been a tedious and boring job, especially inplaceslike;hotels,shoppingmalls,theaters,etcwhereapersonisalwaysrequiredtoopenand close the door for visitors. This human involvement can be avoided by automating the processusingdifferentsensorslikeinfrared,pressure,ultrasonic,laseretc.Inthispaper,automaticdoor control system using Arduino microcontroller was designed. The system combines ultrasonicsensor, servo, and Arduino to achieve the desired goal. When the ultrasonic sensor installed at theentranceofthebuildingdetectsapersonoranobjectwithintherangeofthesensor,asignal is sent to the Arduino microcontroller which controls the servo motor to automatically open the door. The door remains open until the object goes out of range of the sensor and in turn closes the door automatically. The results clearly show that the system is cheap, effective, and areliable means of opening and closing doors in places like retail stores, super markets, factoriesand the like.
