Introduction

In today's digital age, technology has become an integral part of our daily lives, influencing various aspects of our lives, including security systems. One such application is the integration of voice commands with cabinet keys, providing a convenient and secure way to access and control cupboard locks. This research presents a cabinet key system that relies on voice recognition methods to operate keys, offering comfort and safety for its users.

Background

The ESP8266 microcontroller is one of the Internet of Things (IoT) devices that has revolutionized the way we interact with our surroundings. By using this device, users can control cupboard locks from a distance via a smartphone, making it an ideal solution for households and businesses. The mechanism of action is simple: when someone wants to open the cabinet door, they simply send a predetermined sound password. The password is then processed by a microcontroller, and if the pronounced password is correct, the cabinet door will automatically open.

System Design

The ESP8266 microcontroller-based cabinet key system is designed to provide a secure and convenient way to access and control cupboard locks. The system consists of the following components:

ESP8266 Microcontroller: This is the brain of the system, responsible for processing voice commands and controlling the cabinet lock.
Solenoid Door: This acts as an actuator, opening and closing the cabinet door.
Buzzer: This serves as an indicator of key status, sounding when the cupboard lock is successfully opened or closed.
Sound Recognition Module: This module is responsible for processing voice commands and sending them to the microcontroller for processing.

System Operation

The system operates as follows:

Voice Command: The user sends a predetermined sound password to the system.
Sound Recognition: The sound recognition module processes the voice command and sends it to the microcontroller.
Microcontroller Processing: The microcontroller processes the voice command and checks if it matches the predetermined password.
Actuator Control: If the password is correct, the microcontroller sends a signal to the solenoid door to open or close the cabinet door.
Indicator Feedback: The buzzer sounds to indicate the status of the cupboard lock.

Testing and Results

The ESP8266 microcontroller-based cabinet key system was tested five times to evaluate its performance. The results showed that the system performed well, with a high accuracy rate in recognizing voice commands and controlling the cabinet lock. The integration of sound recognition and long-distance control added more value to security, making it a practical solution in the digital age.

Conclusion

The ESP8266 microcontroller-based cabinet key system is an intelligent and efficient choice for maintaining valuables in the closet. With its ease of use and efficiency, this technology is worth considering as an innovation in the field of household security. The increase in sound recognition technology also has the potential to increase the accuracy and response of the system in the future, making it more interesting to be applied in everyday life.

Future Work

Future work on this project can include:

Improving Sound Recognition Accuracy: Further research can be conducted to improve the accuracy of sound recognition, making it more robust and reliable.
Integrating with Other IoT Devices: The system can be integrated with other IoT devices, such as smart home systems, to provide a more comprehensive and secure solution.
Developing a Mobile App: A mobile app can be developed to control the cabinet lock remotely, providing users with more flexibility and convenience.
