Abstract

Morse code is a system of representation of letters, numbers, punctuation marks and signals using a code of dots and lines that are arranged to represent certain characters in the alphabet or certain signals (signs) that are agreed upon for use throughout the world was studied by nilas[1]. This code was coined by Samuel F.B. Morse and Alfred Vail in 1835 was studied by ming[2]. This research aims at how to apply the Background Subtraction method in the design of the morse sign language receiver in the invisible light. Build an Android-based application for recognition of Morse sign language by keeping messages sent using Morse sign language secret through infrared light from the sight of those who can read the message. From the results of the tests that have been carried out, it is concluded that the level of accuracy of testing using the False Match Rate (FMR) obtained a success percentage of 65% from the 26 character data tested. From the 26 character data tested, it was obtained data with the number of characters that were successfully counted correctly, namely 17 characters, while the character data that failed to be counted was 9 characters with a detection result of 26 characters.

Abstract

This study aims to implement the PIR sensor, Arduino UNO and 2 channel relay Module to automatically turn on the lights in the classroom at the STMIK Hang Tuah Pekanbaru campus, where the classes at the Hang Tuah Pekanbaru STMIK campus still use manual switches as controllers lights on. Therefore, a device is designed that can control the lights by using movements detected by the PIR sensor and processed using a computer.This system functions to turn on the lights automatically when someone enters the classroom and turn off the lights automatically when no one is in the class. The hardware used is Arduino Uno microcontroller, PIR motion sensor, 2 channel relay module, and 1.5 volt flashlight. The software for making programs is Arduino IDE where the programming language used is the C programming language. The test results show that the PIR sensor can detect the movement of people entering or leaving a room.
