Rancang Bangun Detektor Gerak Menggunakan Infra Merah Dengan Memanfaatkan Layanan Sms Pada Telepon Seluler Berbasis Mikrokontroler AT89S52

Abstract

A infrared movement detector using Short Message Service based on AT89S52 microcontroller has been designed and realized. The detector can be used for monitoring any passing object in the room. This research can use to detect up to four object in the different room. The detector consisted one control station and one receiver station. The control station using four couple of infrared transmitter and receiver. The receiver station is mobile station used to receive message from control station. This detector consists of hardware and software. The hardware designed with infrared transmitter, an 38 kHz infrared sensor, an op-amp comparator used to compare infrared sensor output voltage. The Transmitter emitting infrared ray and received by sensor. Any moving object passed between them producing the output voltage of infrared receiver change and proceed to comparator resulting high output. This high output signal used as trigger event to running sending message procedure. And the software designed for microcontroler written in C language. The research conclude that the object passed between infrared transmitter and receiver possibly detected and the SMS received by mobile station is match as the location of passing object through the infrared sensor.
