Automatic Braking System using Ultrasonic Sensor

Vehicle technology has increased rapidly in recent years, particularly in braking and sensing system. This invention is used to develop a low cost this problem where the drivers may not apply brake manually but the vehicles can stop automatically due to obstacles. The ultrasonic sensor is used and the function is based on ultrasonic waves. The ultrasonic waves are transmitted from transmitter to the object detected. The waves are then reflected from the object and passed on to ultrasonic receiver. The signals from the receiver are used to operate microcontroller. The microcontroller, according to the distance between the objects and sensors operates the relay switches. These relay switches energize the solenoid valve and according to the pressure inside, brakes are applied.
