IOT Smart Locker

Secure. Smart. Connected.

What is LOX?

LOX is an IoT-enabled smart locker ecosystem. Users can reserve and unlock lockers through a mobile application, while administrators can monitor and manage lockers through a connected system.

Secure

Provides safe temporary storage with electronic locking and authentication.

Smart

Uses sensors, ESP32 control and software logic to automate locker access.

Connected

Connects the mobile app, backend and hardware locker system together.

Why LOX is Needed

No Secure Storage

Many public places do not provide safe temporary storage.

Risk of Theft

Students and passengers may lose personal belongings.

Manual Management

Traditional lockers need keys and manual supervision.

Poor Convenience

Users need a faster and easier way to access lockers.

Our Solution

LOX allows users to reserve lockers, unlock them remotely, monitor locker status and securely store items using a mobile app and IoT-enabled locker hardware.

  • Mobile app reservation
  • Remote locker control
  • Real-time locker status
  • Automatic locking
  • Secure authentication
