Office Occupancy Tracker Pro Kit — Build a Smart Dark-Activated Motion Light with Arduino Uno

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

Walk into a dark room and watch the light turn on automatically — only when it’s truly dark. Then see it stay on for 30 seconds after you leave, just like high-end office occupancy sensors. This kit gives you a real hands-on experience building the exact logic used in security lights, hotel corridors, and energy-saving building systems.

What You'll Build

You’ll create a compact smart light circuit that uses a passive infrared (PIR) sensor to detect human presence and a light-dependent resistor (LDR) to measure the room’s brightness. When motion is detected and the ambient light falls below a set threshold, the white LEDs illuminate for a full 30 seconds. It’s a genuine prototype you can place on a desk, mount near an entryway, or present at a school science exhibition. The build mimics real occupancy sensors found in corporate offices and hotels.

What You'll Learn

• How a PIR sensor translates body heat movement into a digital HIGH/LOW signal
• Reading analog LDR values and setting a darkness threshold in Arduino code
• Using conditional if-else logic to combine inputs from two sensors and control an output
• Prototyping circuits on a breadboard and powering an Arduino project with a 9V battery
