The main objective of this project is to build a smart home device which can be used to control the home appliances via internet. The home automation device that you build can be integrated with almost all the home appliances and can be used to control them remotely from any part of the world.

To facilitate the wireless connectivity with the system, the Arduino Uno will be embedded with a WiFi module. This establishes the internet connection to the system and all the home appliances can in turn be connected and controlled by internet.

The device can also be connected to an Android App which you can develop on your own using some applications like MIT App inventor etc. By using this app, you will be able to monitor and control the home appliances from any part of the world with ease.

You can also include a PIR sensor with this project to make it switch ON automatically the appliances whenever a person enters the room and switch OFF the appliances whenever the person leaves the room.

Home Automation using IoT Project Description:

Arduino Uno: The digital and analog input/output pins are equipped in boards that may be interfaced to various expansion boards and other circuits. Serial communication interface is a feature in this board, including USB which will be used to load the programs from computer.
Voltage regulator: It is used to maintain a constant voltage level and also used for regulating AC or DC voltages. A voltage regulator contain negative feed-forward design or it may also contain negative feedback control loops.
WiFi Module: ESP8266 WiFi module is generally used to establish the wireless communication between the devices. But this module is not capable of 5-3V logic shifting and will require an external logic level converter.
PIR Sensor: It is capable of sensing motion of the human and therefore it is also called as a motion sensor. Whenever a human pass through this sensor it will automatically sense the motion through IR radiation and send the data to the microcontroller.
Relay Driver (IC ULN2803 APG): The relay driver IC that you use will have the following characteristics, 500-mA rated collector current, High voltage outputs – 50 V, Output clamp diodes, Inputs compatible with various types of logic.

Project Implementation:

Step 1: In order to establish connection between the client and the server, the Wifi option in the Smartphone is enabled
Step 2: It is connected to the Wifi module of the system
Step 3: Each electronic/electrical appliance in the system is connected to the digital pins on the Arduino Uno Board
Step 4: A Relay is used for connecting each device to the Arduino, which helps in converting high Voltage supply to low voltage
Step 5: A C-program is loaded on to the microprocessor chip on the Arduino Uno Board which specifies what action is to be performed on receiving particular inputs
Step 6: An Android Application has been developed which enables the end user to monitor and control the appliances from any remote location
Step 7: Socket Programming has been used to achieve client-server communication
Step 8: Successful controlling and monitoring of appliances

Project Brief:

You need to use USB to serial converter that allows the system operation at 3.3V. You can connect the pins of the ESP8266 module via jumper wires to the corresponding pins on the USB. The Arduino Uno connected with ESP8266 WiFi module is used to implement the micro web server for the home gateway. A conventional light switch will be integrated with the Arduino using relay driver module to demonstrate the switching capability. This hardware architecture is very flexible and allows other home appliances and devices to be seamlessly integrated with minimal changes
