1. INTRODUCTION

   Rapid advancements in embedded systems and Internet of Things (IoT) technologies have led to the development of smart home automation systems that improve comfort, safety, and energy efficiency. Home automation enables electronic control of household appliances through wireless communication, allowing users to manage devices with minimal physical effort and increased convenience.For bedridden patients and senior citizens, operating conventional electrical switches and appliances can be difficult due to limited mobility or health conditions. Such individuals often depend on caregivers for basic daily tasks, which can reduce their independence and quality of life. Voice and remote-controlled technologies provide an effective solution by enabling hands-free and accessible interaction with home environments.This project proposes a Voice and Remote Controlled Home Automation System designed specifically to assist elderly individuals and bedridden patients. The system integrates IoT technology with voice recognition and a mobile application to allow

   easy control of household appliances. By offering a low-cost, user-friendly, and reliable solution, the proposed system promotes independent living while reducing caregiver workload in homes, hospitals, and assisted living facilities.Advancements in IoT and embedded systems have made smart home automation possible, improving comfort and accessibility. This system is specially designed to help bedridden patients and senior citizens who have difficulty operating household appliances.

   The system uses a ESP32 micro controller connected to Wi- Fi. It works in two ways: through voice commands using a voice assistant and through a mobile IoT application. When a user gives a command, it is sent to the ESP32 micro controller , which processes it and performs the required action.

   Appliances like lights, fans, TV, and AC are controlled using a relay module. A servo motor is used to adjust the bed position, and an LCD displays the system status. The system works in real time and does not require physical switches, helping users live more independently and reducing dependence on caregivers.

2. PROPOSED SYSTEM

   The proposed system is a dual-mode home automation solution that helps bedridden patients and elderly individuals control household appliances independently. It is built around a ESP32 micro controller connected to Wi-Fi and blue tooth for real-time communication.The system operates through voice commands and a mobile IoT application. Appliances such as lights, fans, TV, and AC are controlled using a relay module, while a servo motor adjusts the bed position. An LCD provides system status updates. Overall, the system is low-cost, reliable, and designed to improve

   convenience and independence for users with limited mobility The system is designed to respond quickly and reliably to user commands by continuously monitoring inputs from voice control and the mobile application. Once a command is received, the ESP32 safely processes and executes it through the connected hardware.Electrical safety is ensured using a relay module that isolates low-voltage control circuits from high-voltage appliances. Wi-Fi communication provides stable and remote access to the system. The design also supports future expansion, allowing additional features and devices to be added. Overall, the system offers a flexible, secure, and user-friendly solution that improves comfort and independence for users with limited mobility.

3. IMPLEMENTATION DIAGRAM

   The system works by capturing the users voice command through a microphone and converting it into a text instruction using a speech recognition module. This command is then processed and sent to the ESP32 micro controller, which acts as the central controller. Based on the instruction, the controller activates the required appliance such as a fan, light, TV, or air conditionerthrough a relay circuit. The system also provides feedback through an LCD or LED display to show the device status. The entire process operates in real time, enabling efficient and hands-free control of household appliances.

   5. HARDWARE MODULES

   1. ESP32 :

      The ESP32 is a low-power microcontroller designed for IoT applications, featuring built-in Wi-Fi and Bluetooth for wireless communication. It has multiple GPIO pins and supports communication protocols like UART, SPI, I2C, and PWM for easy hardware integration. In this project, the ESP32 serves as the main controller, receiving commands from a voice assistant or mobile app and controlling appliances such as lights, fans, and air conditioners through relay modules.

4. FLOW OF PROJECT

Fig.2: Flow of Project

The system uses a 9 V battery with an L7805 regulator to provide a stable 5 V supply, ensuring safe and reliable operation of the ESP32 board and relay modules.It will keep the components safe from high volatge which causes the damage to components

1. Precision motor :

   A precision motor operates using PWM signals from a micro controller to control its shaft angle. It uses a

   feedback mechanism to compare the desired and current positions, rotating until the correct angle is reached and then holding it firmly. This ensures accurate and stable movement, typically within a 0 to 180 degrees range and aslo range from 180 to 0 degrees

   1. SOFTWARE TOOLS:
      1. Arduino IDE (Tool) :

         The Arduino IDE is software that allows writing, compiling, and uploading programs to Arduino microcontrollers, providing tools like a text editor, console, and toolbar to communicate with the hardware for automation projects.

2. Load Control Module:A Load Control Module is an electronic device that manages and automates electrical appliances, allowing them to be switched ON or OFF manually, remotely, or automatically in home, industrial, or IoT systems.
