Office Occupancy Tracker – Arduino-Powered Lighting That Responds Only When Needed

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

Most office lights stay on for hours without a single person in the room. This kit flips that problem into a learning opportunity: you’ll build a working occupancy tracker that triggers a relay only when a person enters and the ambient light is low. It’s the exact principle used in modern smart buildings, stripped down so you understand every connection and line of code.

What You'll Build

An Arduino Uno reads data from a PIR motion sensor and two light‑dependent resistors. You’ll program a logic that ignores motion during bright daylight, then switches on a connected light (or any AC appliance via the relay) when the room darkens and someone walks in. A 16×2 LCD displays real‑time sensor states so you can debug and demo with clarity.

What You'll Learn

• Combine digital and analog sensor inputs into a single decision algorithm
• Calibrate LDR threshold values for different office lighting conditions
• Interface a relay module safely to control AC loads without a microcontroller damage
• Use an I2C‑backpack LCD to log events without blocking the main loop

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

CBSE Class 11–12 students looking for a standout physics or computer science project, B.Tech ECE/EEE undergraduates prototyping for Smart India Hackathon, and ATL Tinkering Lab mentors who want a ready‑to‑assemble automation module. If you’ve already worked with a basic Arduino kit and are ready to handle sensor fusion and AC control, this is the next step.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
