This paper is of great importance for monitoring and controlling the distance between the car and obstacles on the road. The objective of this paper was to monitor and control automatically the vehicle and to reduce many accidents. It is sure that this system will be able to save for human. This system mainly consists of the PIC 16F887A, temperature sensor (DHT-11), ultrasonic sensors (HC-SR04), gas sensor (MQ-2), 20x4 LCD display, motors (DC) and motor driver (L298N). The ultrasonic sensors are used to sense the distance for vehicle state information, which will continuously track for any obstacle from four sides of the car. The temperature changing from overheat of the car engine is monitored by using the temperature and humidity sensor. This system uses the gas sensor which will detect the smoke released by the heating car engine. The PIC 16F887A is used as a controller to control the direction of car. Moreover, if the vehicle detects the obstacles, this system displayed the distance between the car and obstacles on LCD and the safety alarm system contains by using a buzzer.
