Abstract:

The study describes in detail the prototype development of an automated smart door control system that combines automated control with microprocessor logic (Arduino). In particular, the smart door system provides for the automatic opening and closing of doors upon human detection, reducing physical touching and advancing hygiene. Motion detection of humans is accomplished using ultrasonic and passive infrared (PIR) sensors, and ultimately the sensors relay their data to an Arduino Uno microcontroller. The Arduino Uno microcontroller processes the data and thereafter controls a direct current (DC) motor through a motor driver circuit. The design of the prototype was performed using the Arduino IDE and simulation software (Proteus), and the study outlined the then results. The results showed detection of human motion with accuracy, smooth operation of the doors, and reliability of functionality consequent to use in public buildings as libraries, hospitals and offices.
