A Advance Ultrasonic Anti- collusion system using 8051 microcontroller can measure distances up to  2.5 meters at an accuracy of 1 centimeter. AT89s51 microcontroller and the ultrasonic transducer module HC-SR04 form the basis of this circuit. The ultrasonic module sends a signal to the object, then picks up its echo and outputs a wave form whose time period is proportional to the distance. The microcontroller accepts this signal, performs necessary processing and displays the corresponding distance on the 2*16 LCD display. This circuit finds a lot of application in projects like automotive parking sensors, obstacle warning systems, terrain monitoring robots, industrial distance measurements etc.
     This project not only displays the distance, but also activates buzzer and deactivates relay whenever the distance is less than 10cm.
