Introduction In today’s era of intelligent living, the integration of security, automation, and energy efficiency has transitioned from a luxury to an essential aspect of modern home design. This paper presents a comprehensive Smart Home Secure System that seamlessly combines multiple technologies to enhance both safety and sustainability within a household. The proposed system incorporates facial recognition for identity verification, Bluetooth-based door access control, automated lighting triggered by Passive Infrared (PIR) motion sensors, and real-time energy consumption monitoring through Internet of Things (IoT)-enabled sensors. At the core of the system lies the Arduino Uno microcontroller, functioning as the central processing unit that orchestrates communication between various input and output components. It receives data from several sensors, including the HC-05 Bluetooth module, PIR motion sensor, and power monitoring sensors such as the ZMPT101B voltage sensor and ACS712 current sensor. These inputs allow the system to intelligently respond to user commands and environmental conditions. For access control, a 12V solenoid lock is employed to secure the entrance. This lock is operated via a relay and can be unlocked through two distinct methods: either by facial recognition using an externally connected camera system or via Bluetooth commands issued from a user’s smart phone. The integration of these technologies not only enhances the security and convenience of home access but also ensures effective energy management by monitoring and responding to occupancy and usage patterns in real-time.

In the era of advancing automation and the Internet of Things (IoT), people want smarter home setups that are easy to use and flexible. Things like fingerprint locks, remote control, motion lights, and even tracking electricity usage are becoming very common. [1]. In our project, which we named “SMART HOME SECURE,” we’re basically putting all that into one setup. We’ve used face recognition for ID, Bluetooth to open or close the door, motion sensors for switching on lights, and a smart energy meter that connects to the internet it’s meant to be low-cost and should work well in actual homes and in real world conditions.[2]. The system is mainly built around the Arduino Uno, which is the central controller and connects with different hardware parts. To detect whether someone is nearby, a PIR motion sensor has been used it only triggers the face recognition when there's movement, which helps save power and reduces unnecessary processing and load on microcontroller.[3]. For access control, we have used the HC-05 Bluetooth module, allowing the door to be locked or unlocked through a smartphone. This makes entry easier and removes the need to carry keys. To know how much electricity is being used, we added two sensors: ZMPT101B for voltage and the ACS712 for current. The readings from these are shown on a 16×2 LCD screen using an I2C interface, which also helped us reduce the number of wires needed.[4].A 12V solenoid lock is used for securing the door physically. It’s operated through a 5V dual-channel relay, which keeps the high-voltage side (lock) separate from the low-voltage control system, improving safety. Altogether, these components work as a compact and integrated smart system for home automation and security. We’ve tried to make the system more efficient and reliable by adding things like time-based checks, wireless control, and motiontriggered activation. These changes also help improve safety in daily use. The main aim was to fix common issues like the risk of unauthorized access, the need for manual operation, and high-power usage.[5]. This project shows is that it’s actually possible to build a smart home setup that’s affordable
