RANCANG BANGUN SISTEM MONITORING PARKIR MOBIL AREA TERTUTUP MENGGUNAKAN SENSOR INFRA MERAH BERBASIS MIKROKONTROLER AT89S51 DAN BARCODE SEBAGAI SISTEM PENGAMAN

Abstract

Have made design a monitoring system using a closed car park area-based infrared sensors and use of barcode AT89S51 microcontroller as a safety system. The design of this can be exploited for the managers of car parks to ease service and minimize the occurrence of car theft. It has worked before and after the infrared sensor is blocked. This circuit works on two conditions namely high and low. The output from IC 7408 is then used as inputs logic high or low on the microcontroller. Microcontroller sends data to a computer via serial communication. Data is sent in accordance with the microcontroller input port. On the computer displays the location of car parking is available in green and red filled in accordance with data sent from the microcontroller. Barcode is used as a parking card, reading a barcode using a barcode scanner which is then connected directly to the computer. The system has been successfully realized and can show the location of which still lies empty parking lot or have used and know the number of cars being parked. View the parking map on the computer in accordance with the location of a parked car in the parking building.
