Introduction

Along with the advancement of technology everything could and can be possible now a days.

Under such kind of technologies the IoT is also one. Controlling the electrical appliances through android application with the help of

Embedded system and IoT (Internet of Things) everywhere. Generally, In office’s , home’s and factories etc., everywhere we will use the electrical

appliances. To control these appliances through android application we are going for this system.

Project goal

The goal of this project is to develop a home automation system that gives the user complete control over all remotely controllable aspects of his or her home.

The automation system will have the ability to be controlled from a Android mobile based application.

Basic system

Android application

Wireless Device

Controller Appliances

Command through Android application.

Command will be received by the communicator through wireless communication and internet.

The received command will be passed towards the controller from the communicator through serial communication.

Depends on the user command, the controller will give the command to the Appliances

Different communications

Bluetooth, Zigbee, Wi-Fi, GSM, NFC are the different types of wireless communications. In other words, they allow the devices to talk to each other.

Each one of the devices are having their own advantages and disadvantages. But depends on the applications the devices has to be selected.

In these communications Bluetooth, Zigbee, Wi-Fi communications are differentiated here.

Zigbee 802.11(Wi-Fi) Bluetooth

Data Range 20,40,250 Kbits/sec 11 and 54 Mbits/sec 1 Mbits/sec

Range 10-100 meters 50-100 meters 10 meters

Control Methods

On/Off control In this module we can control the home appliances by sending command to Arduino

through android application.

Eg. Light, Serial light, Water heater, Socket control, Wireless charger, etc

On/Off control with voltage variation In this module we can control the home appliances by varying the voltage and sending the command to the

Arduino through android application.

Eg. Dimmer, Fan, Mixie, Grinder, Sound systems, Iron box, etc

Gas leakage detection In this module whenever the LPG gas leakage happened that time it should detects the leakage of LPG gas

and alerts the user through buzzer indications.
