Abstract

This project is about designing and development Vehicle speed sensing is one of a project that develop in gated community area to control car speed by using Radio Frequency Identification and magnetic sensor in school area. This device is developing to warn a user of speed limit in school area. The main component of this project is PIC 16F877A to program the project. The magnetic sensors will summarise the speed of the vehicle and the speed will be display in the LED. If the limit is exceeded, the buzzer will turn ON. This project also uses RF Id to identify the type of vehicle and its plat number for display to LED. For the night version, the buzzer will not operate because the circuit has consisted LDR for night uses. The output of this system can be divided into two parts which are display mode and audio mode. For display mode, liquid crystal display (LCD) is used to display the speed of the vehicle based on condition that have been set. For audio mode, a buzzer is used to warn the driver about the speed if the drivers exceed the limit. The microcontroller analyses the signal, sends the command and measure the speed of the vehicles from first magnetic sensor until the car pass thru the second magnetic sensor. The measured speed is displayed on the LCD display. Advantages of this vehicle speed sensing are low cost, easy to manage and it also provides speed measurement compare to the existing device in the market.
