DIY Radar System Educational Kit – Ultrasonic Scanning Detection Project

Create your own working radar detection system with this student-friendly electronics DIY kit designed for school and engineering projects.

The radar uses an ultrasonic sensor mounted on a rotating servo motor to scan objects in front of it. The controller processes the data and displays detection results on a connected computer interface, demonstrating how real radar scanning systems operate.

This project is perfect for learning:

✔ Distance sensing technology
✔ Rotational scanning systems
✔ Automation and control logic
✔ Electronics project building
✔ STEM robotics concepts

Designed specially for students, beginners, and educational demonstrations.
