This paper presents a smart Baby Cradle Monitoring System designed to provide real-time surveillance and automation for infant care. The system incorporates sensors to monitor the baby's movements, crying, temperature, and humidity levels within the cradle environment. An Arduino-based microcontroller processes sensor data and automates cradle rocking, alerts parents via GSM when the baby cries, and ensures environmental comfort. This solution is aimed at enhancing baby safety and reducing caregiver workload by integrating IoT technology with traditional baby care equipment.
