Abstract
from arXiv · showhide
This paper presents a flexible standalone, low-cost smart home system, which is based on the Android app communicating with the micro-web server providing more than the switching functionalities. The Arduino Ethernet is used to eliminate the use of a personal computer (PC) keeping the cost of the overall system to a minimum while voice activation is incorporated for switching functionalities. Devices such as light switches, power plugs, temperature sensors, humidity sensors, current sensors, intrusion detection sensors, smoke/gas sensors and sirens have been integrated in the system to demonstrate the feasibility and effectiveness of the proposed smart home system. The smart home app is tested and it is able to successfully perform the smart home operations such as switching functionalities, automatic environmental control and intrusion detection, in the later case where an email is generated and the siren goes on.
1. INTRODUCTION
The paper motivates an affordable, scalable, user-friendly smart home system for ubiquitous mobile access, comfort, safety, resource savings, and support for people with special needs. It proposes an Android-controlled system using an Arduino Ethernet micro-web server, user authentication, and voice activation without a PC.
- Smart homes can increase comfort, safety, security, and rational use of energy and other resources.
- The system should be affordable, scalable for device integration, and user friendly.
- An Android app remotely accesses appliances and devices through an Arduino Ethernet micro-web server, eliminating the need for a PC.
- The proposed system requires user authentication and incorporates voice activation for switching applications, especially for elderly and disabled users.
2. RELATED LITERATURE
Prior smart home systems used Bluetooth, internet, SMS, or voice control, but commonly depended on range-limited links, PCs, web hosting, or separate voice-recognition components. The paper positions its design against these cost, power, and accessibility constraints.
- Bluetooth-based systems reduce hardware costs but limit control to the environment within Bluetooth range.
- Internet-based systems commonly use a PC, dedicated web server, database, or web page hosting for remote home control.
- Voice-activated systems may rely on radio-frequency range, PC software, or a separate voice-recognition module.
- These prior designs can increase cost and power consumption through PC servers, web hosting, or separate speech-recognition components.
3. SYSTEM DESIGN
The system combines an Android app with an Arduino Ethernet micro-web-server for remote smart-home control, monitoring, automation, and security. Its design supports authenticated internet access, voice switching, sensor-driven alerts, and standalone operation without a PC.
- System Architecture: The architecture links an Android app over the internet to an Arduino Ethernet micro-web-server that directly interfaces with sensors and actuators.The user device can connect through Wi-Fi or 3G/4G, while the Arduino controller hosts the server and performs requested actions.
- System Architecture: The system covers energy management, security surveillance, environmental regulation, voice activation, and user authentication.Supported devices and functions include lighting, power plugs, HVAC, fire and intrusion detection, sirens, email notifications, and room-temperature maintenance.
- Android Platform App: The app supports authenticated remote access, device monitoring and control, scheduling, automatic environmental control, password changes, and voice-activated switching.Authentication requires the server’s real IP address and a password before the app synchronizes device statuses.
- Micro Web-Server: REST-based web services use standard GET and POST requests to exchange messages between the smart home app and the micro-web-server.The design selects REST because it is lighter-weight than SOAP while providing similar functionality.
- Micro Web-Server: The command-processing routine authenticates users before executing requested actions, while password changes are stored in EEPROM for persistence across shutdowns.Incorrect passwords produce a response and disconnect the client; correct authentication permits the requested operation.
- Micro Web-Server: Interrupt-driven security monitoring detects smoke, fire, gas, or intrusion, activates the siren, and sends email notifications to designated users.The siren can be switched off through the app or configured to turn off automatically after a specified period.
4. RESULTS AND DISCUSSION
Testing showed that the smart home app handled authentication, switching, intrusion detection, and fire detection, with alerts delivered by email and siren activation.
- The app displayed an invalid-password message when authentication failed.
- The system was fully functional for switching, and the interface updated to show appliances’ current statuses.
- Intrusion and fire events were successfully detected, generating email alerts and turning on the siren.A kitchen fire alert was received on both an Android mobile device and a desktop PC.
- The design provides user authentication, intrusion and fire alerts, and voice activation without a dedicated PC or external voice-processing module.The paper presents these features as supporting a low-cost and affordable system.
5. CONCLUSIONS
The paper proposes and implements an internet-based smart home system controlled through an authenticated Android application communicating with a micro-web-server.
- The Android app communicates with the micro-web-server over the internet using a RESTful web service.
- Any Android-supported device can install the app to control and monitor the smart home environment remotely.
- The microcontroller handles all processing, eliminating the need for a PC and reducing system cost.
- Google speech recognition provides voice activation without an external voice-recognition module.
- Future work includes SMS and call alerts and wireless in-home networking to reduce installation wiring changes.
