Project Summary

Internet of things is a technology of the future that has already started to touch our homes. Here we propose an IOT based home automation system using raspberry pi that automates home appliances and allows user to control them easily through internet from anywhere over the world. Our proposed system consists of a microcontroller based circuit that has lights and fan connected to it along with LCD display and Wifi connector interfaced with raspberry pi. Our system interacts with out online IOT system that IOT Gecko free web interface for controlling our home appliances with ease. After linking with IOT Gecko, the user is allowed to send load switching commands over IOT to our circuit. The circuit receives the commands over IOT by connecting to internet using wifi connector and then the raspberry processor processes these commands. After this the processor now processes these instructions to get user commands. It then displays these on an LCD display. Also it operates the loads (lights and fan) for switch them on/off according to desired user commands. Thus we automate home appliances over internet using raspberry pi.Internet of things is a technology of the future that has already started to touch our homes.

Project Objectives

The objective of this project is to complement a  low  cost,  reliable  and  scalable homeautomation  system that can be used to remotely switch on or off any household appliance, using a microcontroller to  achieve hardwaresimplicity, low cost short messaging service  for feedback  and voice  dial from  any phone to toggle the switch state.

Project Implementation Method

The design project was consummated by highlighting the problems to be solved and an algorithm was spelt out to realize the solution. This was also buttressed using a flowchart thus simplifying the writing of the Arduino source codes. The inputs to the analog is never digital but analog, this allows the choice of functions to read the analog signals that changes from 0V to +5V depending on the level of illumination and voltage reference set. And if statement is copiously used, it is followed by an else statement, which executes when the expression is false  An i2C scanner was downloaded online for the determination of its address. Maximum output current for the Microcontroller is 20 mA hence there was a need to have a transistor switch to drive a relay which switches the Lighting units.

The ubiquitous application of microcontroller in automobiles, robotics and industrial system has made its studies important. An Arduino board has a microcontroller and other extras that make its programming and debugging easy. we just need to install an Arduino IDE which is downloadable online on his computer from www.arduino.cc, write the program, compile it and load it into the board No need for a separate programmer that costs extra money. Its functions are easy to understand, a gesture which makes it ideal for prototyping by inventors. An Arduino uses C programming language

The project uses the simplest Arduino board referred to as Arduino Uno It is a small microcontroller board. In this case an Atmega 328 that has 28 pins is used. Some of the components surrounding it are voltage regulator, reset button and Crystal oscillator; they allow the board to communicate with the computer without separate programmer. In order to enhance connections with the board, there are fourteen I/O pins; each pin is used as Input or Output pin depending on the specification in the codes written in the IDE. Also, there are six other analog input pins, A0 to A5, they take in Analoque quantity and convert them into a number between 0 and 1023. In the same vein, pins 3,5,6,9,10 and 11; though are digital can be programmed as analogue output pins depending on the codes written in the IDE.

Benefits of the Project

The project is designed by using Arduino uno board for the development of home automation system with Bluetooth which is remotely controlled and operated by an Android OS smart phone. Houses are becoming smarter and well developed by using such kind of advanced technologies. Modern houses are gradually increasing the way of design by shifting to centralized control system with remote controlled switches instead of conventional switches

In order to achieve this, a Application module is interfaced to the Arduino Uno board at the receiver end while on the transmitter end, a Graphical User Interface application on the cell phone sends ON/OFF commands to the receiver where loads are connected. By touching the identified location on the Graphical User Interface, lamps are used as loads in this project can be turned ON/OFF remotely by using this technology. The loads are operated by using Arduino Uno board through thyristors using triacs and OPTO-Isolators.

Technical Details of Final Deliverable

Power source and power management

Every IoT device needs to be supplied some sort of power in order for it to operate. This can include  battery, energy harvesters, or line. You need to understand the customer usage habits and product intent of your IoT device.You also need to consider power management for your ICs,wireless technology. and management for your sensors/actuators. You can save power by only transmitting data at certain intervals while the rest of the time it is in  "sleep" or low power  mode.  Also consider what type of power will your device have access to. Will your IoT device be stationary and have access to the line ? Or does your device need to be portable and need to have on board energy storage. Also consider remote applications that might need to use energy harvesters such as solar cells. You also need to consider fault protection because IoT devices commonly are under varying environmental conditions..

  Sensors/actuators

Most IoT devices either gather information of the physical world through sensors or manipulate the physical world through actuators. They can be as simple as flex sensors to as complicated as MEMS airflow sensors. Once you have a sensor(s)that you will use you need to interface it with your MCU this will require amplifiers or analog to digital converters. 

Processor and memory storage

it Processor is the heart where you process data and run your software. Depending on your node application you might have to run your RF stack and algorithms. Memory is also neccary to store local data such as, session data, user settings ect. You can also look into SoC or system on chips which integrate many functionalities such as power management, memory, wireless transceiver and processor.

 Wireless communication

You have a lot of choices when it comes to wireless communication. There are modules that integrate your RF communication which include rf shield,amplifier,oscillators and antennas.  On your board you have to determine what type of wireless transceiver  you will use. These transceivers will send and receive data wirelessly.   Determine what range your IoT device needs to communicate over as well as data rates. For example, will the user be controlling the device through their cell phone or will you have nodes part of a larger meshed network. Again determine the use case because different communication protocols  require more power,cost, and board space .  Some examples include wifi,blueooth and zigbee protocols.

 UI/UX

A lot of IoT devices can be controlled by your smart phone or web app. However, it might be necessary to have user interfaces on the product. So for example for nest the device needs to have a screen to display and control the settings. You might need to consider physical knobs or buttons as well.
