DOWNLOAD ABSTRACT

AIM:

Design and Development of Bluetooth based home Automation.

PURPOSE:

In homes and offices, there is lot of loads. All these loads are in various places. Controlling switch boards are far away from loads. While operating loads it is very difficult to find out whether they are ON or not, especially if they are far away. There are various types of load control systems available in market and expensive. We want to design a low cost load control system with Bluetooth. Here we propose solution like Bluetooth based home automation.

DESCRIPTION:

This project includes Bluetooth (HC-05) module, which is connected to Arduino through UART interface. Three loads connected to Arduino digital pins which are Bulb, LEDs and fan respectively through relays.

WORKING:

User can control loads from Bluetooth Application. Here we have customized app in our mobile. It has buttons on screen. By pressing keys we can control Bulb, fan, and LEDs respectively. All these loads status displayed on 16X2 LCD and in APP screen. Here we used own customized app and we can keep our college name on top of app screen.
