Child Tracking and Notification System via iBeacon

Abstract

         This study aims to develop a child monitoring and alert system using iBeacon technology to detect a child’s position within designated areas, including the home, vehicle, and classroom. The system employs an iBeacon receiver attached to the child, integrated with a NodeMCU ESP32 microcontroller and a SIM808 module to send alert notifications via phone calls, a LINE alert system, and the Baby System Alert website. The performance evaluation demonstrated that the system can accurately detect the child’s distance up to 5 meters and immediately send alerts when the child moves outside the predefined safe zone. Status messages such as “within the area” and “out of the area” are transmitted to the LINE alert system and displayed on the website. Furthermore, if the child leaves the home or school area for more than 10 minutes, the system automatically initiates a phone call to the parent. In vehicle scenarios, if a child remains inside the car for more than 5 minutes, the system triggers an emergency phone alert. The results indicate that the developed system effectively enhances child safety and enables parents to quickly and reliably receive information regarding their child’s status.
