Next-Generation IoT Smart Cradle System for Infant Health and Monitoring

The Next-Generation IoT Smart Cradle System is designed to provide continuous monitoring and automated care for infants. The system uses an Arduino microcontroller as the main controller to collect data from various sensors such as a heartbeat sensor, pulse sensor for SpO₂ monitoring, temperature sensor, and sound sensor. The sound sensor detects the baby's crying and automatically activates the cradle movement using a DC motor and motor driver to soothe the infant. Health parameters including heart rate, oxygen saturation level, and body temperature are continuously monitored and displayed on an LCD screen. A NodeMCU module uploads the collected data to the cloud for remote monitoring by parents or caregivers. If any abnormal condition is detected, a buzzer generates an alert notification. The proposed system enhances infant safety, reduces parental stress, and enables real-time health tracking through IoT technology.
