Project Description:
*****

What if you could track human movement wirelessly — in real time — using a millimeter-wave radar and an ESP32-S3 touchscreen display?

In this video, I’ll show you how I built a portable human presence detection system using the RD-03D mmWave radar sensor and the MaTouch ESP32-S3 Parallel 5-inch TFT Touch Display.

Features covered in this project:

Real-time human motion tracking
Wireless communication using UDP over WiFi
Live visualization of distance, angle, and speed
Interactive radar-style animation (just like the movies!)
No PC, no wires — 100% standalone and portable

This is not your ordinary PIR sensor or ultrasonic radar. The RD-03D mmWave radar can detect even micro-movements — like someone sitting still — and stream live data to a touchscreen device.

Whether you’re interested in home automation, security systems, smart sensing, or IoT radar applications, this project demonstrates how to decode radar data, send it wirelessly, and render it visually — all with just ESP32 and Arduino code.

I’ve also shared:

Full Arduino source code (TX + RX)
Circuit diagram
Setup instructions
All available on my website: https://www.electroniclinic.com

Use cases:

Motion-triggered alerts
Smart lighting automation
Remote human detection
Security & surveillance
Elderly care and fall monitoring
