Oct 31, 2017 · 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.
Oct 03, 2010 · Ultrasonic Range Finder Interfacing Sample code for AVR. To understand our code for Ultrasonic Range Finder Interface you need to have basic knowledge about timers in microcontroller. In short a timer is a register which increments it value at predefined intervals without the need of any help from CPU.
How to Interface an Ultrasonic Sensor with an LCD Using a Microcontroller Dev Kit November 02, 2017 by Nick Davis Let's interface an ultrasonic sensor and a lighting system! In this project, we'll design a sensor subsystem and then use it in a parking sensor application. EXPERIMENT NUMBER 8 Interfacing the 8051 with an External Sensor I INTRODUCTION: External sensors play an important role in embedded systems. Most digital applications require some kind of sensor. There are a wide variety of sensors available: from a simple keypad of buttons to ultrasonic sensors measuring distance.
MPX4115 a motorola pressure sensor is powered by 5V and delivers output voltage ranging from 0.25V to 4.75V corresponding to pressure 15Kpa to to 115Kpa resprctively.sensor detects pressure produces corresponding voltage which later converted into 8-bit binary number by ADC0804 and passes an accordingly scaled voltage to microcontroller which converts it into digital data to I was working with interfacing of hc sr04 ultrasonic sensor with lpc1768 so as to display the distance from an obstacle to the sensor on an LCD display in centimeters .. there were no errors in the code, but distance is not being varied its showing always as 0 cm.. i could not find the problem.. i'm sure that sensor is in good condition Jul 05, 2018 · Ultrasonic sensor interface with microcontroller 8051 by=MicroMagic.
