摘要

In the modern world of rising automation and safety regulations, real-time monitoring of room occupancy has become a necessity in rooms such as classrooms, Conference hall, offices,and laboratories. This project introduces a low-cost, sensor-based Real-Time Occupancy Monitoring System that accurately counts the number of people entering and leaving a room using Cx-491 compact photoelectric sensors with retroreflective reflectors. The system utilizes an Arduino Uno to interpret sensor data and refresh a 7-segment LED display of the present occupancy level. In case the number of occupants in room is above a pre-set threshold, an audible warning (buzzer) is initiated and a fault code is flashed, alerting users to a threshold violation.The system has been engineered to be direction-dependent, where an entry or an exit is recognized based on sequential sensor triggering. The system also functions satisfactorily with any change in the light, thanks to power shutdown protection being handled by a 12V–2A Mini UPS. Integrated into a handcrafted 3D-printed casing and being constructed over a PCB prototype board, the system is miniature-sized, resilient, and easily portable.This intelligent monitoring technology offers an energy-saver, scalable solution to occupancy management and is thus ideal for implementation in smart building infrastructures and guaranteeing compliance with crowd control protocols.
