Low-Cost Smart Home Automation System with Advanced Features

Abstract

The proposed system demonstrates the design and implementation of a smart automation system that can be implemented in different places such as homes, industries, hospitals, or other busy places. The proposed system is also very beneficial to handicapped people so that they can also increase their quality of life by being less dependent on others. The proposed model is an Arduino-based system and is used to control electrical devices using mobile applications along with the feature of voice commands. It runs in two modes of operations manually and Auto (as per need) using sensors and IoT. The use of two ways of controlling (i.e from mobile application and auto and manual control) makes this system advance. The system works in real time as the status of each switch and the state of load whether ON or OFF are indicated by the LED indicators present on the manual control side. This system is of low cost, and easy to troubleshoot and its code for interfacing with different sensors with Arduino is easily available. Moreover, the proposed system can be placed in connection with any supply board in the room, one just needs to match the relay connection with the load.
