distance finder based on at89s52 and ultra sonic sensors hc sr04

Ultrasonic range finder using 8051 .
A simple ultrasonic range finder using 8051 microcontroller is presented in this article. This ultrasonic rangefinder can measure distances up to 2.5 meters at an accuracy of 1 centi meter. AT89s51 microcontroller and the ultrasonic transducer module HC-SR04 forms 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 ....etc

ABSTRACT:
Blindness is more feared by the public than any other ailment. Artificial vision for the blind was once the stuff of science fiction. But now, a limited form of artificial vision is a reality .Now we are at the beginning of the end of blindness with this type of technology. In an effort to illuminate the perpetually dark world of the blind, researchers are turning to technology. They are investigating several electron ....etc

ULTRA SONIC motor is a newly developed motor, and it has excellent performance and many useful features, e.g.: high-torque density, low speed, compactness in size, no electromagnetic interferences, and so on. USM is a kind of piezo motor. The proposed speed control scheme is assumed for these applications because they require quick and precise speed control of actuators for various load conditions. A speed control method of USM using adaptive control is proposed.
Artificial Neural Network (ANN), which follows the biological neural cells in bra ....etc

Detection of corrosion damage in aircraft wing skin structures is an ongoing NDT challenge. Ultrasonic methods are known and well-accepted techniques, which are relatively simple to carry out in terms of setup, probes and instrumentation and operator training. However, with conventional inspection from the top surface using a transducer at normal incidence (0o to the normal to the surface) producing a visual picture in the form of a C-scan, it is very tie consuming to point-by-p ....etc

ultrasonic sensor code for obstacle detection using avr

It is essential to give your robot eyes for preventing crashes. Ultrasonic sensors, also known as transducers, have a similar working system as a radar or sonar by interpreting the echoes of radio or sound waves generated by the sensor. In this way, a robot can detect obstacles and the distance to obstacles. In this article, we make an overview of most popular ultrasonic sensors used in robotic applications and tutorials to learn how to interface and programming these sensors in order to ....etc
