DIY Smart Staircase and Hallway Lights That Follows You | AmbiSense v1.0 - Intelligent Lights
Published at : 23 Dec 2025
In this video, I reveal my latest innovation - AmbiSense - a revolutionary radar-powered lighting system that detects your presence and creates dynamic illumination that follows you through dark spaces. Unlike traditional motion sensors, this system uses advanced 24GHz radar technology to precisely track your movement and distance, creating a seamless lighting experience. Watch as I demonstrate how this intelligent lighting solution transforms hallways and staircases by illuminating your path exactly where and when you need it. The customizable LED patterns respond in real-time to your proximity, creating an interactive lighting environment that's both practical and visually stunning.
I'll guide you through the entire build process of the AmbiSense system:
a. Setting up the ESP32 microcontroller with the LD2410 radar module b. Connecting and configuring NeoPixel LED strips c. Installing the software and customizing settings through the intuitive web interface d. Optimizing power requirements for different LED strip lengths
Things you will need - a. LD2410 Sensor b. ESP32C3-Supermini Microcontroller c. WS2812B (+5V) LED Strip
I am working on Version 2 and then next versions to add new features and enhance functions and support. let me know which feature would you like to have in this one.
