Pengukuran Kecepatan Kendaraan Bermotor Berbasis Mikrokontroler Atmega8535 Melalui Komunikasi GSM

Abstract

Have been designed a measurement speed of vehicle device by using microcontroller ATMega8535, wich is equipped with two infrared sensors as a means of detecting vehicle speed, the distance between sensor 1 and 2 is 50 cm. Distance data the sensor 1 with sensor 2 was set to microcontroller by using the keypad that is connected to microcontroller. If a vehicle passing on the higway through sensor 1 and sensor 2, sensor will send input data to the microcontroller for calculating the time.Distance and time data obtained processed by using the program on the microcontoller speed calculation.So that speed data compared to the maximum data which be set to a microcontroller by using the keypad. After that the distance data, time and speed displayed on the LCD which has been connected to the microcontroller . If the speed exceed the maximum speed limit , the speed data will be sent by the GSM module is connected to the microcontroller in the from of SMS. Maximum speed of SMS data will be received by the GSM modem which is connected to Personal Computer and SMS data will be displayed in the form of data base on the PC. This device has been tested and obtained good results.
