Introduction

I. INTRODUCTION

In the current day, integrating technology into our daily lives has become critical. The demand for efficient and secure home management systems has accelerated research and development in home automation and security. GuardianPi is a unique solution that integrates home security and automation into a single platform. Unlike previous solutions which primarily provide either security or automation capabilities, Guardian pi effortlessly incorporates both, together with added smart features.

Home automation systems frequently lack effective security capabilities, while traditional security systems do not offer the convenience of managing home appliances. GuardianPi overcomes these constraints by providing a full system that incorporates remote access control, fire warnings, break-in and burglar detection, alongside real-time temperature and humidity monitoring.

The system’s core is a Raspberry Pi, which is integrated with multiple sensors and modules to effectively monitor and control the home environment. Users interact with the system through a secure web interface, which allows them to log in, view real—time data, and remotely control appliances. GuardianPi’s unique combination of functions and user-friendly design makes it an affordable and effective option for modern home management.

II. LITERATURE REVIEW

GuardianPi combines home security and automation with a Raspberry Pi to create a comprehensive system. The DHT11 sensor monitors temperature and humidity, the real time data is updated on the webpage, when temperatures exceed certain limits, a fire alert is sent by SMTP email. The RFID module provides secure entrance. A proper RFID tag triggers the solenoid lock, whilst faulty tags or if the person standing in front of the door for longer than the stipulated time, generates an email alert for the user, signifying the potential risk of break-in. Home automation is controlled via a relay module attached to the Raspberry Pi’s GPIIO pins.

GuardianPi overcomes the limitations of standalone systems by integrating security and automation. Using the Raspberry Pi, the system is both inexpensive and efficient, removing the need for additional peripherals. This research demonstrates the feasibility of merging different smart home technologies into a single platform, thereby enhancing both safety and convenience.

III. SYSTEM OVERVIEW

This section provides an overview of the system’s operational workflow, Fig 1 briefly depicts the overview of system’s working. It begins with user interaction via a web-based interface, accessible from any internet enabled device.

Upon logging in, users gain access to a dashboard real-time data on temperature and humidity levels, alongside controls foe household appliances, User commands such as toggling appliances states, are transmitted to the database for storage and processing, The Raspberry Pi acting as the central processing unit, retrieves status values from the database. Through programmed logic, it orchestrates the control of electrical appliances based on the value retrieved from the database. A ‘0 value indicates the raspberry pi to turn OFF the corresponding mapped electrical appliance and a ‘1 indicates the raspberry pi to turn ON the corresponding electrical appliance.

After processing user commands, the Raspberry Pi interfaces with various sensors deployed throughout the home, including those for fire and intrusion detection. These sensors continuously monitor environmental conditions and security parameters, sending relevant data back to the Raspberry Pi for analysis.

The system’s capacity to seamlessly integrate user interaction, sensor feedback forms the foundation of its operational efficiency and reliability.

This interface serves as the primary point of interaction, enabling seamless engagement with the GuardianPi system.
