Project Description: ***** Waveshare’s HMMD mmWave Sensor might just be the BEST motion and presence detection radar sensor you've never heard of! In this video, I’ll walk you through everything you need to know—from how to use it with an ESP32, how to control relays/lights, and how to monitor it from anywhere in the world using Blynk IoT!
Key Highlights of this Video: • What makes the HMMD mmWave Sensor different from other radar Modules like the RD-03D?
• How to send UART commands and decode raw data frames (in HEX). • Live demonstrations with cardboard, fabric, wood, glass, and even a • Ceiling fan test!
• Define custom detection ranges and control devices like bulbs. • Create a real-time security system with Blynk V2.0 – monitor from anywhere in the world. • Distance range setup, micro-motion detection explained (wall & ceiling mount). • Learn how to extract distance and energy values even when no libraries exist!
What You’ll Learn: • HMMD mmWave Sensor wiring with ESP32 • How to read UART data manually • Raw hex to real distance conversion • Controlling relays with motion detection • Integration with the Blynk App (V0 virtual pin) for mobile alerts
Safety Warning: Be cautious when working with AC power (110/220V). Use proper insulation and safety standards when controlling mains voltage with relays.
