Project description:
The Intelligent Infant Monitoring System using a Smart Crib was successfully designed, implemented, and validated to enhance infant safety through real-time, non-invasive monitoring. The system integrates ultrasonic sensors to measure an infant's distance from crib boundaries, a distributed pressure sensor array to monitor weight distribution and posture across the mattress surface, and an accelerometer to detect crib tilt or abnormal motion. All sensor data is processed in real time and presented on a PC-based monitoring interface, where the crib is logically divided into safe and unsafe zones, providing clear visual feedback on the infant's safety status. When unsafe conditions are detected, the system automatically triggers visual alerts, including a red LED warning, enabling caregivers to respond promptly. The completed prototype was extensively tested under multiple operating scenarios and demonstrated reliable detection of infant movement, posture changes, and safety risks. By combining multiple sensor modalities, the system delivers robust performance independent of lighting conditions and offers a practical, scalable, and cost-effective solution for intelligent infant safety monitoring in both domestic and healthcare environments.
