Abstract / Introduction

Home automation is the future of household management, offering convenience and control over electrical appliances and environmental factors like temperature and humidity. As technology advances, these systems are becoming smarter, more autonomous, and can significantly reduce energy consumption and electricity costs. A key application of this technology is for people with mobility challenges, such as the handicapped or elderly. Voice-controlled systems, in particular, enable users to effortlessly control appliances by simply giving a voice command, eliminating the need for physical interaction with switches.

This project proposes a voice-controlled smart home system designed specifically to enhance the independence and quality of life for handicapped individuals. The system uses a Bluetooth module for seamless data transmission from a user's smartphone to the home's electrical loads. By using a microcontroller-based design, the system receives signals from the user's device and directs them to respective relays, which then control appliances like fans, lights, and air conditioners. The system is designed to allow users to control all appliances at once or manage each one separately.

A critical and life-saving feature of this system is its ability to generate a help signal based on a voice command. This functionality is crucial for emergency situations, providing a vital safety net for the user. This project represents a practical and impactful application of digital logic design, combining hardware and software to create a highly reliable and beneficial home automation system.

Functional Requirements:

Our complete system will have:

        A Smart Dispenser Module:

        A pill dispensing mechanism capable of dispensing medication on a pre-set schedule.

        An on-device LCD/OLED display to show the time and next medication to be taken.

        A buzzer/alarm system to provide audible reminders.

        A real-time clock (RTC) for accurate scheduling.

        A pill detection sensor (e.g., IR or force-sensitive resistor) to confirm a successful dispensing event.

        A microcontroller (e.g., ESP32) to control the hardware and manage communication.

        A Mobile Application:

        A user-friendly interface for caregivers to remotely set and modify medication schedules for the dispenser.

        A dashboard to display the current status of the dispenser.

        A module that displays a historical log of all dispensing events, including timestamps.

        A real-time alert module to notify the caregiver via push notification or SMS if a dose is missed.
