Office Occupancy Tracker Kit with Arduino Uno + Servo
Build an Office Occupancy Tracker with Arduino Uno & Servo – Real‑Time People Counting
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Whether you’re managing a shared conference room, monitoring lab access, or building a smart office solution for a hackathon, this kit lets you create a functional occupancy tracker that counts every person entering a space. The PIR sensor detects motion, the Arduino increments a counter, and the bright OLED displays real‑time occupancy. A servo can be programmed to swing a physical ‘Occupied/Vacant’ sign, teaching you mechanical control alongside embedded logic.
What You'll Build
A compact, battery‑powered occupancy meter that mounts at a doorframe. When someone walks past, the PIR triggers the counter, updating the count instantly on the OLED. The DS3231 real‑time clock stamps each entry, so you can later analyse peak hours. Once occupancy hits a preset limit, the servo rotates to show a red ‘Do Not Enter’ flag, then resets when the count drops.
What You'll Learn
- Integrate an HC-SR501 PIR sensor with Arduino Uno R3 and avoid false triggers through debounce logic.
- Control an SG90 servo to react to a digital threshold, moving from 0° to 180° based on occupancy count.
- Interface a 0.96‑inch OLED display over I2C and show live count, timestamp, and status messages.
- Use a DS3231 RTC module to log occupancy events with accurate time, building a foundation for data logging projects.

Who This Kit Is For
Ideal for CBSE Class 11-12 students exploring embedded systems, B.Tech ECE/EEE undergraduates working on mini‑projects, and participants in Smart India Hackathon or ATL Tinkering Labs. Even hobbyists setting up a home office will appreciate the practical introduction to occupancy sensing with immediate visual feedback.
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.
What if I get stuck during the build?
Scan the QR code inside the box to start a conversation with the AI companion, which knows every wire and line of code for this tracker. You can also message us on WhatsApp for a direct reply from our engineering team.
Can I power the tracker without the battery and use USB instead?
Yes, the Arduino’s USB port can supply power while you upload code and test. The 9V battery snap is included so you can mount the finished tracker near a door without a wall socket.
How do I avoid false triggers from the PIR sensor?
Turn the sensitivity trimpot on the HC-SR501 clockwise to reduce range, and add a 2‑second cooldown in the code. The AI companion will walk you through these adjustments with exact values.
Can I modify the kit to track people exiting as well?
The base project counts only entry events. With an additional PIR sensor and logic to detect direction, you could upgrade later. This kit provides the core skills to expand on your own.
