This paper focuses on to develop a system to keep the vehicle secure and protect it by the occupation of the intruders. The main purpose of this work is to develop a system automatic speed control of vehicle and accident avoidance using heart beat sensor, alcohol sensor and ultrasonic sensor, LPG sensor and LDR. Heart beat sensors are used to monitor drivers pulse rate, if there is abnormal pulse rate variations in driver the vehicle will be stopped immediately. If any obstacle is detected in running vehicle depends on distance automatically control the speed of vehicle using ultrasonic sensor. Vehicle accidents under the influence alcohol are prevented using alcohol sensor. If any accident occurs then a piezoelectric sensor uses the piezoelectric effect to measure changes in pressure, acceleration, temperature, strain or force by converting them to electrical change. And short message service using GSM along with the latitude and longitude location by using GPS will be sent to predefined numbers. LPG Sensor senses any leakages inside the vehicle and it will give the alert by glowing the LED and Buzzer will happen. The one more objective is various intensities of light. i.e., high beam or low beam of head light falling on the opposite vehicles head light and the basic general idea of manual dipping and this same idea is converted in to electronic format with these circuits using LDR.
