A digital lock using WebSerial technology offers a modern, secure, and convenient access control system, primarily leveraging an ESP32 microcontroller. This system functions by hosting a web interface that is accessible via a local Wi-Fi network. Users can connect to the network and enter a pre-set password through the WebSerial interface. The microcontroller processes the input and controls a relay that activates the lock mechanism. If the entered password is correct, the relay is triggered, unlocking the door for a specific duration before automatically re-locking, thus ensuring secure and controlled access.
Key Features
- Web-Based Interface: The ESP32 microcontroller hosts a web interface that users can access through a local Wi-Fi network. This interface allows users to enter the password for unlocking the door, providing a user-friendly and easily accessible control point.
- Secure Access Control: The system enhances security by ensuring that only users with the correct password can trigger the relay to unlock the door. The password is processed directly by the microcontroller, reducing the risk of unauthorized access.
- Automatic Re-Locking: After a successful unlock, the door automatically re-locks after a specified period, further enhancing security by preventing accidental or intentional bypassing of the lock.
- Remote Control and Monitoring: The web interface enables real-time, remote access control, allowing users to manage and monitor entry points from anywhere within the network’s range.
Applications
- Residential Security: Homeowners can use the digital lock to control access to their property, providing an additional layer of security. The ability to manage entry remotely through a web interface makes it particularly useful for monitoring who enters and exits the home.
- Office Access Management: In office buildings, the digital lock can manage employee access, ensuring that only authorized personnel can enter certain areas. This system can be easily integrated into existing security protocols, enhancing overall office security.
- Smart Locker Systems: The technology is ideal for smart locker systems used in parcel delivery and storage. Users can securely access their parcels by entering a password through the web interface, reducing the risk of theft and unauthorized access.
- Hotel Room Access: Hotels can implement this system to remotely control and monitor room access, improving both guest security and operational efficiency. This system allows hotel staff to manage room access without the need for physical keys or cards, streamlining the check-in and check-out process.
