Faculty monitoring system with mobile application using received signal strength indication

Abstract:

The purpose of this study is to provide a Received Signal Strength Indication (RSSI), which is the measurement of the power present in a receiver, for the faculty monitoring system in the EECE Department using bluetooth technology and a mobile application. The system is consisting of bluetooth readers and tags, Arduino, web server and a mobile application. The bluetooth tag contains a unique MAC address that the bluetooth reader accepts if it is within the range of the threshold value of the signal strength. Using an Arduino in which it will only accept the MAC address of the tag if its signal strength is within threshold value programmed and rejects the tag if it is above the threshold value programs the bluetooth reader. The data will be now forwarded to the web server and will be displayed using the mobile application. In processing the RSSI values for the effective threshold, for this study, Gaussian Filter and Average Filter technique were applied. These techniques removes the abnormal values and rejects it. The researchers emphasize the significance of understanding and analyzing the behavior of RSS for the threshold values and with the given results, the researchers concluded that there are factors affecting the behavior of RSS depending on its placement and the interior design of a certain room. The group believed that by considering these factors before implementation will improve faculty monitoring system. Overall, the system worked properly upon on the right threshold value of RSS and the use of Bluetooth technology can be a great help in the advancement of monitoring system. Therefore, RSS can be used in contactless monitoring system.
