Background
Secure, Low-Power Smart Access Control for Residential and Commercial Spaces
The Smart Door Unlocker was developed as a secure and flexible access control solution for modern residential and commercial environments. Traditional locking systems lack remote access, scheduling capabilities, and integration with smart ecosystems. This project aimed to create a compact, low-power smart lock system that enables seamless, secure, and convenient door access through mobile devices.
Challenges
Key Project Challenges
1
Security & Encryption
Ensuring all communication between the smart lock and mobile devices is protected through robust encrypted protocols.
2
Low Power Consumption
Designing a system capable of long-term, continuous operation without frequent battery replacements or power interruptions.
3
Reliable BLE Connectivity
Maintaining stable, low-latency wireless communication between the lock hardware and the paired mobile application at all times.
4
Multi-Platform Support
Developing a single access control application that works reliably and consistently across both Android and iOS devices.
5
Hardware Flexibility
Adapting the physical system design to function across different door types including wooden, glass, and sliding installations.
Solutions
How We Built It
Our Approach
Encrypted BLE Smart Lock with Cross-Platform Mobile Control
A smart locking system was developed using the ESP32 platform with BLE 4.0 connectivity, built on the ESP-IDF framework. The device communicates securely with a custom mobile application available on Android and iOS, allowing users to unlock doors, manage access schedules, and monitor battery status. Encrypted communication protocols were implemented to ensure secure data exchange. The hardware design supports multiple form factors, making the solution adaptable to various door types including wooden, glass, and sliding doors. The system was optimized for low power consumption and reliable performance, with scalability for future cloud integration.
Benefits
Value Delivered

Encrypted communication ensures every unlock request is authenticated and protected against unauthorized access attempts.
Remote & Scheduled Access
Users can manage entry permissions and configure access schedules directly through the mobile application with ease.
Cross-Platform Compatibility
Full support for both Android and iOS ensures all users can control access regardless of their device preference.
Flexible Installation
Adaptable hardware design supports a wide range of door types and installation environments without custom modifications.
Low-Power Efficient Design
Optimized for extended battery life, delivering continuous and dependable operation with minimal maintenance overhead.
Client Feedback
What the Client Said
"
Security was our biggest concern going in — we needed something we could actually trust, not just something that looked smart. The encryption is solid, the app works identically on both our Android and iPhone devices, and we've had zero reliability issues since installation. Being able to grant and revoke access remotely without handing out physical keys has completely changed how we manage our premises.
