Jun 30, · A simple ultrasonic range finder using 8051 microcontroller is presented in this article. We have different ways to measure the distance. Ultrasonic range finder using 8051 datasheet. Output Video R I A L. One way is to use Ultra Sonic datasheet Sensor or Module for distance measurement.
This Ultrasonic Range Finder system measures the distance up to 4 meters with an accuracy of datasheet 3 mm. This article explains you how to measure the distance using 8051 microcontroller. The sensor works on 40KHz when a trigger signal of 10us is given it transmits a 40KHz wave waits for the echo. Ultrasonic Range Finder Project. Jan 02, · Ultrasonic range finder using 8051. The system consists of an 8051 microcontroller datasheet LCD Display an ultrasonic sensor. Ultrasonic range finder system consists of an ultrasonic sensor which operates like SONAR technology.
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.
ultrasonic range finder using 8051 datasheet
The microcontroller accepts this signal, performs necessary processing and displays the corresponding distance on the 3 digit seven segment display. The echo signal can be obtained from the Echo pin of the Ultrasonic module. The length of the of echo pulse is proportional to the distance of the object/ obstacle.
