Multi-Tenant Apartment Access System Kit with ESP32 + Relay
ESP32 Multi-Tenant Apartment Access System Kit – Build RFID Floor Control with Relay & Web Admin
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine owning a building where tenants only access their assigned floors, and every entry is logged and viewable from a browser. This kit lets you build that reality: a professional-grade multi-tenant access system powered by an ESP32. Using RFID cards, a 4-channel relay simulates per-floor elevator or door control, a real-time clock stamps logs on a microSD card, and a password-protected web admin panel lets you add users and review access history from any device on the network.
What You'll Build
A fully functional access control prototype that reads RFID card UIDs, checks floor permissions, triggers the correct relay for the tenant’s floor, logs the event with timestamp to SD, and serves an admin web panel over Wi-Fi. All components mount inside a durable enclosure, ready for demonstration or as a blueprint for a real apartment system.
What You'll Learn
- Interfacing MFRC522 RFID reader and programming card UID matching for floor-specific access
- Controlling multiple relays via ESP32 GPIOs to simulate per-floor elevator or door locks
- Implementing real-time logging to a microSD card with DS3231 RTC timestamps
- Building an ESP32 web server with admin panel to add/remove cards and view access logs

Who This Kit Is For
B.Tech ECE/EEE final-year students building IoT-based automation prototypes, professionals designing smart access solutions for apartment complexes, and Smart India Hackathon teams needing a working RFID relay system. If you manage a building and want a functional demonstration before a full-scale deployment, this kit delivers the logic and hardware you need to test floor-specific access control firsthand.
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 gives you step-by-step troubleshooting, and you can message us on WhatsApp for personal guidance.
Can I deploy this as a final product in a real apartment building?
This kit is a learning prototype; for real-world installation you would need industrial-grade relays, safety certifications, and possibly a commercial enclosure. However, the logic and firmware are fully transferable to a production system.
Does the kit include the web admin panel code?
Yes, the complete ESP32 firmware with web server and admin panel is provided. The AI companion walks you through uploading and customizing the code.
How can I expand beyond four floors?
The 4-channel relay module handles up to four floors. You can add more relay modules on the same I2C/GPIO bus, and the RFID logic supports unlimited floor assignments per card with minor code adjustments.
RFID assigns floor-specific access. Elevator relay per floor, entry log to SD, admin panel via web browser.
