Office Occupancy Tracker Kit – Self-Routing LoRa Mesh Network with Arduino Nano

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

Transforms any office floor into an intelligent, wire-free surveillance zone. You assemble eight battery‑powered sensor nodes that pair PIR motion detection with reed‑switch door triggers, then network them over a self‑routing LoRa mesh. When an intrusion or occupancy event occurs, the alarm message hops from node to node until it reaches the central gateway panel—no Wi‑Fi, no cloud subscription, no single point of failure.

What You'll Build

Eight hardened sensor nodes, each enclosed in a weather‑resistant case, that detect motion and door openings in real time. The nodes talk to each other over a 433 MHz LoRa mesh: if the direct path to the gateway is blocked, the signal relays automatically through neighbouring nodes. The Arduino Nano‑based gateway displays alerts instantly and can log occupancy patterns for security audits or energy‑management dashboards.

What You'll Learn

• Configure RA‑02 LoRa modules and implement a mesh routing protocol on Arduino Nano.
• Design power‑efficient battery circuitry using 18650 Li‑ion cells and TP4056 charge management.
• Integrate HC‑SR501 PIR sensors and magnetic reed switches for dual‑mode event detection.
• Deploy a self‑healing wireless sensor network that adapts to environmental obstacles and node failures.

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Professionals designing decentralised security for corporate offices, B.Tech ECE/EEE final‑year students tackling IoT mesh capstone projects, and startups prototyping LoRa‑based building automation for Smart India Hackathon or investor demos. Equally valuable for IIT, NIT, VIT or BITS research scholars working on low‑power wireless sensor networks.

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.
