Shared Office Occupancy Light Kit with Arduino Uno — Know Which Desks Are in Use at a Glance

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

Turn any shared workspace into a privacy‑respecting occupancy dashboard. Instead of walking around to check who’s at their desk, you build a system where four passive infrared sensors feed a central Arduino, and an LED matrix lights up one pixel per occupied spot. No cameras, no logins — just a glance at the matrix tells the whole room how many desks are active. This kit is your complete hardware package, from PIR modules to the MAX7219 display, backed by a build companion that guides you through every connection and line of code.

What You’ll Build

You’ll wire four HC-SR501 PIR sensors to an Arduino Uno, each placed on a different desk, and connect a MAX7219 8×8 LED matrix that updates in real time. The matrix can show a simple count or a pattern, so anyone in the office can see occupancy at a glance without interrupting colleagues. The whole assembly fits on a breadboard and runs from a 9V battery, keeping it portable for demo days or temporary co‑working setups.

What You’ll Learn

• Wiring multiple PIR sensors to Arduino GPIO pins and power rails without signal cross‑talk
• Programming the Arduino to read digital inputs from HC-SR501 modules and filter out false triggers
• Driving an MAX7219 8×8 LED matrix to display real‑time occupancy counts
• Integrating capacitive decoupling and pull‑down resistors to stabilise a multi‑sensor system
