Home Automation With Arduino

HISTORY

I started this project as a school project. Actually, I wanted to create something that would benefit the society. Therefore, I started examining what are the different problems that are exiting in the world that could be solved. Then, I found out that "Misuse of Electricity" and "Shortage of electricity" are some of the problems faced by the people of India. Therefore, I designed this system for the above mentioned purpose.

Supplies:

The materials used in my project are given below along with their respective price (all price are in INR per piece);

Breadboard - INR 60

Four Channel Relay Module- INR 130

HC-SR04 Ultrasonic distance sensor - INR 80

Arduino Uno - INR 1500

Generic Jumper wire Male to Male - INR 5 (about 50-70 required)

Generic Jumper wire Male to Female - INR 5 (about 50-70 required)

9v Power Adapter - INR 100

HC - 05 BLUETOOTH MODULE - INR 250

Therefore, The total Cost of my project is around INR 4000

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: PRINCIPLE

The working principle of this whole system is that:

1)The ultrasonic sensor will detect human presence

2) Relay module will control all the appliances but it will not be connected to sockets as there may be a need to turn it on when there are no people in a room

3) Smart Edge will take various sensors values display via Brainium server since this kit has sensor with high accuracy

*The relay module will be installed between the appliances and switch so to run the appliances there will an automated switch (run by Arduino Uno) and a normal manual switch

** If there is a need to run any appliance without human presence it can be achieved for 2 hrs via a customized app.

***To run the fan ( or ac) there will be two conditions first the human presence and second the temperature should be high enough(22 degree Celsius)

****To run the light there will be two conditions first the human presence and second the light intensity should be high enough (4.5 analog value)

Step 2: BUILDING THE HOUSE

You can use any kind of model for this purpose, but the condition is that you need to have a house made of any material without any roof. I am enclosing the pictures of my (made) house.

Step 3: MAKING THE CONNECTIONS

The Smart Edge Agile needs no wiring while the remaining components may be wired AS ABOVE.

Step 4: WRITING THE CODE:

The Code for Arduino IDE is given below in the attachment part and for more details please see the comments. A detailed description of the app is given in the the video in the last video in testing part.

Step 5: MAKING APP

I used the MIT App Inventor to make the app. For detailed description please refer to the second video in the principle part. Here are the screenshots of the blocks:

Step 6: TESTING

You may proceed for testing the prototype by following the video as above.
