Office Occupancy Tracker Kit with ESP32 + DHT22
Office Occupancy Tracker Kit — Build a Smart Office Dashboard with ESP32 & DHT22
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
After 10 hours of soldering, coding, and assembling, you’ll have a fully functional office occupancy management system. Walk into your office, tap an RFID card, and the lights turn on, the fan spins, and the door locks behind you — all while live temperature, humidity, and motion data stream to a custom web dashboard accessible from any device on your network. This kit puts you in full control of your workspace, with web-based manual overrides for lights, fan, and door lock, plus over-the-air firmware updates for future enhancements.
What You'll Build
A network-enabled smart office console: an ESP32 brain reads DHT22 temperature/humidity, HC-SR501 motion, and MFRC522 RFID tags. A 4-channel relay module switches AC loads for office lights and fan, while a solenoid lock secures the door. The 0.96-inch OLED shows sensor readings locally; a real-time web dashboard lets you monitor and toggle every output from any phone or laptop on the same Wi‑Fi. OTA updates let you push new firmware without touching the board again.
What You'll Learn
- ESP32 embedded programming and WebSocket‑based real‑time web interfaces
- Integrating DHT22, PIR, and RFID modules with industrial-grade relay control
- Designing and deploying over-the-air (OTA) firmware updates wirelessly
- Building a durable, enclosed prototype with proper power management using buck converters and protection diodes

Who This Kit Is For
This kit is tailored for B.Tech ECE / EEE students building an advanced capstone project, tech-savvy office managers deploying IoT automation, and Smart India Hackathon participants who need a reliable, OTA-capable system. IIT, NIT, VIT, and BITS students working on home automation will also find a ready‑to‑deploy hardware and firmware stack that saves weeks of prototyping time.
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?
The AI companion walks you through every wiring step, code upload, and dashboard setup. You can also reach out via WhatsApp for quick human troubleshooting.
Does this kit include everything needed for the web dashboard?
Yes—all hardware is included and the firmware source code comes pre‑loaded with a responsive dashboard you can access on any browser. You can customize the interface after the build.
Can I integrate this with Blynk or Home Assistant later?
Absolutely. The code uses standard WebSockets and HTTP, so you can add MQTT bridges or Blynk widgets with minor modifications. It's open and extensible.
Is the enclosure suitable for permanent office installation?
The included ABS plastic box has cutouts for sensor vents, OLED, and RFID reader, plus mounting slots for wall or desk placement. It protects all components and looks professional.
Office — Web dashboard controls lights, fan, lock. DHT22 + PIR feed live sensor data. OTA update capable.
