Attadance system using infrared sensors

Abstract

Abstract This study aims to design and develop a system for student counters in the room. This Attadance System is based on the Arduino Uno R3 microcontroller by using an IR sensor to detect the object. This system is expected to facilitate the work of teaching staff in conducting attendance activities in the classroom that will not cut the time of teaching and learning. The main purpose of this Attadance System is to help student counting in the room automatically. The automatic student counting attendance system that uses a microcontroller and IR sensor is designed and built through several stages, namely: (1) analysis and identification of attadance and component system requirements and other tools that support the success of system assembly; (2) designing components and mechanical design as containers and supports; (3) system implementation; (4) system testing and evaluation of the overall Attadance System. The testing of the automatic student counter attendance system shows the results in the form of performance consisting of the experiment number, IR sensor detection distance, and the state of the light and environmental conditions of the light intensity. The sensor is able to detect distances of up to 6.5 cm if in good light intensity conditions. But in conditions of poor light intensity the sensor can only detect up to 5.5 cm.
