Build a Room Occupancy Energy Saver with the ESP32 Auto Light Kit

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Move beyond simple motion‑triggered lights and into true occupancy intelligence. This kit gives you everything to build a system that reads PIR motion and door sensor data, then runs a lightweight TensorFlow Lite model directly on an ESP32‑CAM to classify the room as occupied, vacant, or in transition. The result is a custom energy‑saving controller that learns when to cut power—perfect for homes, hostel rooms, or offices trying to trim electricity waste.

What You'll Build

A fully functional auto‑light energy saver. You’ll mount two PIR sensors for wide coverage, install reed switches on doors, and wire them to the ESP32‑CAM. The pre‑loaded model fuses motion patterns with entry/exit events to decide room occupancy, triggering an active buzzer (or an external relay) when the space becomes vacant. By the end, you’ll have a compact, enclosed unit ready to deploy behind a switchboard.

What You'll Learn

• Train and deploy a TensorFlow Lite model on an ESP32 microcontroller for on‑device inference
• Interface HC‑SR501 PIR sensors and reed switches for multimodal room monitoring
• Design a sensor fusion algorithm that combines motion and door events to infer occupancy
• Build a power‑efficient embedded system using buck converters and linear regulators
