IoT-Based Automatic Bed Vacancy Detection in Hospital

This project presents an IoT-based automatic bed vacancy detection system for hospitals using IR sensors and a servo motor-controlled entry mechanism. The system is designed with four IR sensors representing four hospital beds, and an additional entry IR sensor at the gate. Each bed's occupancy is monitored in real time using its corresponding IR sensor. When all four IR sensors detect occupancy and the entry IR sensor is triggered, the system identifies that no beds are available and restricts access by keeping the servo motor-controlled gate closed. Conversely, if any of the bed sensors do not detect occupancy—indicating a vacancy—and the entry IR sensor is triggered, the system automatically opens the gate via the servo motor to allow patient entry. All bed occupancy data is uploaded to the cloud using ThingSpeak, enabling real-time monitoring and data analysis for hospital staff. This solution aims to improve patient management and optimize resource allocation in healthcare facilities.
