Ultrasonic Distance Measurement

Our project is a low-cost, user-friendly ultrasonic distance meter. It uses sound waves to detect and calculate the distance of nearby objects, making it a handy tool for non-contact measurement.

The sensor transmits and receives ultrasonic pulses, and a microcontroller converts the analog signal into a digital format for accurate distance calculation. This information is then displayed on an LCD screen for easy viewing.

This simple and affordable system offers a reliable way to measure distance without touching the target object.

📌 Feature¶

🔰 Code¶

We used 'mikroC PRO' cooding for the distance measurement using PIC 16F877A Microcontroller and HC-SR04 Sensor.

We upload this code to PIC 16F877A Microcontroller via 'PICkit 2'.
