Introduction: Smart Home With Arduino

About: Hi, my name is Nikodem Bartnik. I live in Poland, I'm 18 years old. I like to program and create robots, devices and things. In the future, I want to start a company that creates new technology. Right now I ...

Hello.

I will show you how to build your own smart home. It shows the temperature both inside and outside, if the window is open or closed, shows when it rains and make alarm when the PIR sensor senses move. I made the application on the android to display all the data (you can also watch it on browser). You can see temperature in your home and other information from all over the world! Application is translated to english and polish. I built it because I wanted to make my own smart home and control it. If you want, you can make your own smart home, all you need is parts (listed below) and a lot of desire. So let's get started.

Explanation of acronyms for beginner:

GND - ground

VCC - power

PIR - move sensor

Step 1: Parts

All the parts cost me $90

- Arduino

- Ethernet module ENC28J60

- Thermometer DS18B20 x2

- Microphone module

- Rain sensor

- PIR sensor

- Reed switch

- Relay

-resistor 4,7k Ω

-twisted-pair cable

-ethernet cable

-tools (soldering, screwdriver)

Step 2: Connection

Above I added picture from fritzing with connection. If you have a problem with it leave a comment.

Step 3: Program

First you need to do is download, extract and import this library to arduino IDE. And download 1Wire library from here, Dallas temperature from here and import them to arduino IDE too. You can upload this program to your arduino. In the comment is an explanation of the code.

Step 4: How It Works?

When you click refresh in your app or in browser Arduino sends data to smartphone/browser. Application gets source code from each page ( /tempin, /tempout, /rain, /window, /alarm) and displays it on your phone.

Step 5: Appliaction for Android.

To instal app on your android phone you need to make this (you can see it on the picture above):

1. the firs first step is download smartHome.apk file

2.Send apk file to your phone

3.Open file manager and locate smarthHome.apk file

4.Click on it and click install (if you have enabled the option to install applications outside the google play you need to turn it on)

5.You have finished the installation, you can enable the application



Application is translated to english and polish. In browser you can turn on and off light but in app not because I can't do that, sorry.

Step 6: Application Configuration

I'll explain how the application works. It's shows all data from your home. You can click on settings icon to edit your IP address and turn on or off alarm. When you turn on alarm, app get data from PIR sensor in service and if it's detected move in your home it's make a notification. App retrieves the data from the motion sensor every minute. In IP field you must enter your IP address. You can check it here.

Step 7: Browser

Type in your browser your ip / all. There you can see all the data and turn on and off light.

You can use this instead of the application on android.

Step 8: Port Forwarding

You need to open port on your router. Open your router configuration and set arduino ip and open port 80. You can see it on image above.

Step 9: NO IP (optional)

You can set up an account at no ip but this is not necessary. In the picture above you can see how to configure it.

Step 10: Test It!

If you want to see the data on your computer you can do this by typing into your browser yourip / all (e.g. 12.345.678.901/all) or use android application.

Remember to leave a comment and click favourite if you like my project :)

Step 11: EDIT: Android App Source Code

Because many people asked me about android source code I add it below.

Hi When I try to run the program it I am getting a error saying " error compiling on Arduino leonardo"

Error.JPG

i am getting server timed out error while connecting thorugh browser also the relay is continuously connecting disconnecting. please help

Hello,

I still have an error in the compilation. Someone has an idea what to change?

Interesting but this is not smart ... its just playing with Arduino cheap modules. Also you could use a ESP8266 Arduino WiFi module instead of ENC28J60. You can find here more about what smart house should be. Thank you for your work!

can you send the video of your prototype

can i know the block of this app in appinventor?

CAn i know the code for this project on the W5100 shield?

Please can u tell spesifically which changes u have in code for the w5100 shield?

How can I send to the measure value of soil moisture to android phone with ethernet module (enc28j60)?

Is it possible?

I need your arduino code which You already write on ardunio ide

Thanks for the instructions. I made it but, I used different Ethernet shield which is W5100. It doesnt need special library, just use the libraries provided by Arduino IDE. Just need to make over the code. Fortunately, it works like a charm!

Great!

hello brother Ahmed.
am doing this same project but am stuck in ethernet module.
can u plz share the details of it. currently am using arduino mega and Ethernet shield module W5100,so if u have the sketch and connections ..plz share it ..thank u ...!
my email : mirzzz21@gmail.com

please if you find solution i need it , the same proplem ,

yassermunther2003@yahoo.com

Thank you for your sharing. I want to ask somethings:
after use "no ip" are we need to adjust port setting on router or not? For example if my dynamic "no ip" adress is "127.253.252.80" and can we use directly in our arduino code as like this ?
static char myip[127,253,252,80] ;
And second question about forwarding:
for example my arduino adress is "192.168.0.200" and after that in my router to setting this adress like this "192.168.0.200:8080 or :8181. So can ı use this adress outside of my network? For example ı want to check one of sensor situation in my home when ı am out side of home. Than ı write this 192.168.0.200:8080. Can ı see to sensor position?

Hi

I've got some problems with code. Can you help me please, because I'am new in arduino.

Hi ther. I am stuck at ethershield library. I have tried 100s new downloads. the new ethercard works. can anyone tell how can i mod to the code to ethercard library?

Hi can anybody help me with a strange problem. I am using all the same equipment. the code doesnt give any error but the module doesn't take IP from the router, I have tried 3 different routers, IPs and ports. It just happens when I am using the "ethershield" library. when i use ether card library or the UIP library the modules takes the IP and example sketches work. now I have two options.

Ether I change the code to newer "ethercard" liberary or I fix the problem. I have been struggling for weeks. any help will be much appreciated
