Abstract

In our day-to-day lives, it is found that there are a lot of time is wasted on finding the misplace items such as the car keys, wallet, handbag and so many more. For encounter the problems, an in-depth analysis on the Bluetooth based item tracker on market with the mobile application was conducted such as the Tile and Track R. Besides, the wireless technology been used in lost item tracking device and method been use for indoor positioning to locate on our belongings has been study. In addition, the trade-off between ‘platform-independence’ and ‘energy-efficient’ solution was discussed in literature reviews. Smartphone had becoming the essential things that can bring convenient to our daily lives such as communication, social and even work. Hence, a smartphone based items tracking via Bluetooth Low energy is designed to allow more user to use the tracking system. Therefore, in this project the prototype item tracker with Bluetooth low energy is designed which allow the user to keep track on their belongings through launch the smartphone application. The mobile application design has provided the initial crude tracking of a tagged item (tracker), whereas, the exact localization can be assisted by audio-visual aids (buzzer) and RSSI to proximity the distance between mobile and the device (tracker). Lastly, an experiment on Receiver Signal Strength Indicator (RSSI) on an actual tracker was conducted to study the reliability of RSSI technique on measure the distances. From the result, it was found that the RSSI signal was not consistence and easily fluctuated by the external factor which is not suitable for accurate distances measurement. However, it can be used to approximate the distances between the tracker and the user (smartphone) in term of near or far.
