Abstract

This paper presents a development of an Adaptive Distance Alert Safety System (ADASS) on child tracking using Arduino microcontroller. A developed prototype of ADASS is designed to alert guardians in detecting human or children presence in a selected covered area. It comprised with a portable module called transmitter which hold by a child and a receiver hold by a guardian. The module works as guards to keep alert on the child existence if the child goes beyond the selected safety area. The system designed which provides three adaptive different signals coverage with Arduino microcontroller. Adaptive signals and different sound volumes are alert in the distance alert area are set as 50m, 70m and 100m as the adaptive signals. Buzzer sounds is created to react with frequency signal and produces different levels sound strength which are low, medium and high volume followed the set of distance of the alert area. Short Message Service (SMS) is sent to guardian if the child is outside the signal range. The Communications signal for the alert system from transmitter to receiver uses Radio Frequency (RF) signal. The RF signal is analyzed based on the adaptive distance alert. Result presents a prototype of ADASS that designed with three new parameters and alerts evaluation is successfully identified in cases of child appearance.
