1. Introduction

IoT stands for the phrase Internet of Things, where all the tests taking place come from the fact that it is the way we are living, delivering, and operating not only in business but in many other industries. Instantly IoT can be an application through which a (plethora of objects) that are assigned to the internet of things are interconnected mutually, with the end result of making a smart social environment that makes living convenient and enjoyable. In consumer spheres, IoT applications include smart houses which have smart devices connected and automatically perform tasks such as turning on lights, TVs or heat in case of need, thus reducing he energy consumption and improving the security [1? ]. [ Industry sector consists of predictive maintenance systems, real-time tracking the equipment and products, and supply chain optimization, all of

ceur-ws.org ISSN1613-0073 these advances can be made by IoT. Just the phrase Internet of Things (IoT) itself demonstrates how this technical idea has hit the highest point nowadays. Hence, these connections involve millions of networked objects, devices, and systems interacting, communicating with each other, and exchanging data without any human intervention. Electronic gadgets may be in form of simple everyday items like household appliances and wearables to complicated items like industrial equipment and environmental sensors. In addition, IoT could be (tailored) to build innovations in diferent areas such as healthcare, transport, agriculture, and town planning. Organisations can derive valuable information from the device data that are connected through IoT whereby they could take better future steps and launch their new product lines and services [ 2 ]. IOT devices are commonly used in surveillance security applications and automation in agriculture also [ 3, 4, 5 ].

Existing IoT has a number of challenges, including security, power consumption, data privacy, user experience, and cost [ 6 ]. We addressed all of these issues in our work by ensuring that there are no security breaches, meaning that hackers cannot access personal information or take control of household devices, and by creating user interfaces that are simple to use and comprehend, even for those without a formal educational background. In terms of cost-efectiveness, we chose to use Node MCU rather than Arduino because it is less expensive and has Wi-Fi connectivity.The existing home automation systems address the issues related to traditional home management, such as lack of eficiency, convenience, and security. The proposed solution involves the seamless integration of NodeMCU, [ 7 ] an Android application, [ 8 ] and Firebase to create a user-friendly smart home system. This system ofers users a comprehensive platform that enables remote appliance control, energy-eficient lighting, and real-time security alerts. Where Fig 1 shows you how diferent hardware were connected to Node MCU. To achieve the above things, we need necessary components for this work that are Node MCU (ESP8266), a light-dependent resistor (LDR) for detecting ambient light levels, relay modules for managing electrical appliances, a Wi-Fi module for enabling Wi-Fi connectivity for the Node MCU, microcontroller parts for connecting sensors and controlling relays, and a suitable power source for the Node MCU and its connected components. While coming to detail of each sensor, The ESP8266 Wi-Fi module serves as the foundation for Node MCU, an open-source development board and firmware. It enables easy programming and integration of Wi-Fi capabilities into IoT applications. The Node MCU functions as the primary Internet of Things device in this work, managing and keeping an eye on household appliances.

Alight-dependent resistor (LDR) operates based on photo conductivity. Photo conductivity is an optical phenomenon in which the material’s conductivity increases. When Photons stimulate electrons in semiconductor material to conduction band. These photons in the incident light should have more energy than the semiconductor material’s band gap to cause electrons to jump from the valence band to the conduction band. As a result, when high-energy light impacts the device, an increasing number of electrons are stimulated to the conduction band, resulting in a huge number of charge carriers. The result of this process as the circuit is closed, more current lfows through the gadget, indicating a decrease in resistance [ 9 ].

Integration between hardware and software components involves numerous steps and considerations in which each role plays a great job to ensure seamless operation as a single unit. First it begins with the design of hardware components entitled to various utilities namely sensors, micro-controllers, actuators, and communication modules. These are the components carefully chosen and configured to meet requirements as per the size and cost of the work [ ? 10, 11]. Moreover, the next step in the development of IoT devices is software, where firmware is made to manage hardware parts, gather valuable data from sensors, process data, and connect with other devices. Depending on the limitations of the hardware, programming languages like C, C++, Java, C#, or Python are frequently used for this purpose [12]. Communication protocols are essential for allowing Internet of Things devices to communicate with central servers and each other. Network Infrastructure, bandwidth, dependability, security, and other considerations are taken into account when selecting protocols such as HTTP, Android Applications, and proprietary ones [ 10, 13 ]. To guarantee the integrated hardware and software components operates as intended, testing and validation are essential. This includes validating against functional requirements and user expectations as well as unit testing, integration, eficiency, and safety testing. Successful integration of software and hardware components in IoT demands necessary planning, design, implementation, and testing [ 10 ]. The Scope of IoT has a wide range of applications in home automation, providing an array of features that are intended to turn living spaces into intelligent, networked areas. Controlling light systems is a key component of IoT home automation. Users of smartphones or voice commands can remotely control lighting with IoT capabilities, such as brightness, colour, and scheduling. In addition to ease of use, these systems provide security features like energy optimization based on occupancy patterns and natural light levels in daytime. Additionally, wearable technology, smart beds, and connected health monitors are some of the ways that IoT home automation supports wellness and health monitoring by ofering insights into individual health metrics and enabling preventive care practices. The desire for smarter, more connected living spaces and technological advancements have led to an overall expansion of IoT in home automation. In section 2, we described literature review.

Adopting Bluetooth technology and a smartphone application, the system provides the users with an ability to control home appliances when away from home. The system does its job properly by adapting components like Arduino and relay switching circuits to make it fully cooperative with the given instructions. Disadvantages might be intimidating of installation and maintenance, but information technology is somehow and someway capable of standard users with little or no technical knowledge. Figure demonstrates core system structure which includes Arduino, Bluetooth modules and relay networks. The future plans include online integration for remote control and voice command features with the purpose of additional simplification of usage by both manual and voice control. Mostly speaking, the system could be seen as an appropriate remedy for home automated, which is certainly oriented at acquiring more features and upgrowth.

4. Results and Discussion

The purpose of our Seamless Smart home control is used to control the home appliances like television, lights, fans, Air conditioner, etc through the Mobile app and through the voice control commands via mobile app. Our work results in diferent unique features like Manual mode where user can hit the switches to ON/OFF switches physically, SET TIMER MODE – where in this mode the user can set the time to Of and On the specific appliance in the scheduled time that the user has set, Auto mode – where the user selects this auto mode to control lightning , based on ambient light conditions and the last feature is Voice control mode - which can be accessed through voices like Alexa. This work is eficient as anyone can, which means the user who registers in this app can control their home appliances not only in the home but can control from anywhere in the world. And here we have used node MCU model instead of Arduino board where the Node MCU is capable of handling or controlling the advance technology like home appliances that are wifi portable. While coming to Security, only the actual user of the app can control or have the access to operate these devices through app but whereas, if that user wants any other person to access then that would also be possible by making certain changes in the settings and where the main user can list the people who can access and who cannot and can also remove them accordingly.

Node MCU is going to be heart of this work. Node MCU connects all the other instruments or systems and can control the whole system. It receives commands from the user via mobile application or through the sensors. And then it will make a decision based on the command the user will give then it sends the processed command to the relay switch and then, this relay switch can operate ON and OFF any device based on the command that user gives. Fig. 4 shows the hardware set up of Seamless Smart Home Control System.

To operate the system, we created the two user interfaces that were Fig. 5 and Fig. ??. Where Fig. 5 interface was created with voice control features that had been integrated with an Alexa app. And Fig. 6 user interface was created in Arduino IoT Cloud Remote app. User can use any of the user interface to operate the system. We have tested the system and app in Realme X7, Samsung A31 and OnePlus Nord.

The comparison of cost analysis between developed system (Seamless Smart Home Control) and existing system [ 1 ] is shown in Table 2. By comparing the table data, we can say that this Wi-Fi portable Home based appliances system is much more cost efective.
