Rancang Bangun Sistematika Absen pada Suatu Ruangan dengan Tampilan Record Data Microsoft Excel Menggunakan Koneksi PLX-DAQ Berbasis Arduino

Abstract

This study aims to produce an Arduino-based fingerprint attendance model and to determine the performance of the device. This tool is connected to fingerprints which are interpreted with Arduino Uno and PLX-DAQ which are formatted with Microsoft Excel. This study uses an optical sensor type fingerprint to detect the fingerprint of the user. This study uses the Arduino Uno microcontroller as a data processor and can see the results of the data in the form of identity, date and time from the user through the code in the program on the Arduino which can later store and change attendance data. This tool also uses PLX-DAQ to view data results in the form of identity, date and time of the user and can be summed up in Microsoft Excel data format. In electronic attendance this is done to make it easier to see the overall level of discipline of the user with his presence when the user arrives along with fingerprint evidence of the user in question, it can also be managed more easily and increase productivity for the user which makes it easier for the microcontroller. From the results of this test, the results of the trial as a whole obtained the results of the percentage of feasibility of the tool in terms of quality characteristics Performance has an interpretation of 95% which is said to be very good or accurate. This tool has good accuracy so that it can be used in monitoring absences in an office.
