Abstract: The issue concerning children due to abduction, disappearance and threats were of great concern to the parent. Daily surveillance of their kids would seem incredibly difficult for working parents when safeguarding their kids. Therefore, a smart beloved tracking system (BTS) is developed to protect children from emergencies whenever pressing the button. The system comprises of the Arduino-nano board and a GSM with an OLED display and then further equipped with SMS notification function to send a SMS to the parent. The goal is to build a portable device related to the safety of the child and to establish a notification system for alerting the current position and to send SMS to parents whenever the child feels unsafe. Wide communication coverage by using GSM features in comparison with Bluetooth communication and appealing compared with the current monitoring unit on the market. BTS prototyping has demonstrated the ability to manufacture the proposed design and successfully demonstrate the ability to track children.
