Ultrasonic Distance Measurement using HC-SR04 and AT89C51 Microcontroller
In Assembly And Embedded C
This project demonstrates how to interface the HC-SR04 ultrasonic sensor with the AT89C51 microcontroller to measure distance in real-time. The system generates a 10μs trigger pulse, captures the echo duration using Timer 0, calculates the distance using the time-of-flight principle, and displays the result on a 16x2 LCD.
The project is programmed in Embedded C and compiled using the Keil µVision IDE.
Project Highlights:
Trigger pulse generation for HC-SR04
Echo pulse timing using 8051 Timer 0
Distance calculation using time-to-distance conversion
Display output on LCD
Suitable for:
