Light Sensor Based Side Indicator Alert for Automobiles

Abstract

This project is developed for the purpose of side indicator alert for vehicle riders based on light sensor. The main part of the unit is light sensor, microcontroller, driver, vibration motor and LCD display. Light sensors are connected in left side indicator and right side indicator. Light sensor is used to sense the light intensity. When the side indicator is ON even after crossing the turning point, the light sensor sends the signal to the microcontroller through driver. The microcontroller sends the control signal to the vibration motor through relay driver. The vibration motor creates the vibration in the hand bar. Thus the vehicle riders can easily identify the on condition of side indicator. Further, LCD display is used to display which side indicator is ON condition. The microcontroller program is written in assembly language. This project is portable and cost effective.
