DIY Smart Presence Sensor – Automate Your Lights Like a Pro

This is a 3D-printed enclosure designed to house an ESP32-Wroom, an LD2410C mmWave presence sensor, and a VEML7700 light sensor. The case provides a compact and secure setup for your smart presence detector, which automates lighting based on actual presence and ambient light levels.

Why This Sensor? Unlike traditional motion sensors that turn off while you're sitting still or activate unnecessarily, this smart presence detector only sends data to Home Assistant when necessary, reducing database load and improving efficiency.

📌 Features of the 3D-Printed Case: ✅ Ventilated design for accurate sensor readings ✅ Compact & secure fit for ESP32-Wroom, LD2410C, and VEML7700 ✅ Easy mounting options for walls or ceilings ✅ Modular design for future sensor upgrades

🔧 What You Need: ESP32-Wroom (e.g., Wemos D1 Mini ESP32) LD2410C mmWave sensor VEML7700 light sensor 3D-printed case (Download STL files here)
