IoT-based Door Automation and Smart Health Monitoring System

This project presents the design of an automated access control system that aims to enhance security through the use of an ultrasonic motion sensor and a live heartbeat check. This system makes use of an ultrasonic sensor which detects any motion within a certain radius directing a signal to the controller based on Arduino. The controller is able to communicate with a script written in Python that queries API for the pulse of the user in question. Using these parameters, the system compares the real-time heartbeat of the pulse taken against the thresholds set beforehand. When the parameters exceed the range, the control unit within the Arduino will trigger the servo to unlock the door. Another scenario the parameters are within range, the door will remain closed. Such a system is able to increase the control measures in biological information system as it enables people to open the door while maintaining their hands free. The outcome demonstrates that by combining simple hardware components with data processing techniques, a reliable and secure automated access system can be created with minimal manual intervention, improving security while ensuring ease of use.
