Distance Measurement of an Object or Obstacleby Ultrasound Sensors using P89C51RD2

Abstract: Distance measurement of an object in the path of a person, equipment, or a vehicle, stationary or moving is used in a large number of applications such as robotic movement control, vehicle control, blind man's walking stick, medical applications, etc. Measurement using ultrasonic sensors is one of the cheapest among various options. In this paper distance measurement of an obstacle by using separate ultrasonic transmitter, receiver and a microcontroller is presented. The experimental setup and results are desc… Show more

“…. The function of the braking system is deceleration and absorption deceleration by stepping brake pedal, the brake pads compress the rotor attached to the wheel, which than force the vehicle to slow down due to friction.The brake absorbs the kinetic energy of the vehicle mechanically reduce the speed [10]. In mechanical, friction converts the kinetic energy into heat [9,10].…”
