Arduino Uno R3

There are some problems in our country. One day me and my Friend discussd to this problems. In our streets there is little bit security because of social in equality. In or society no one is safe even not richer because the no of robbers are increase day by day they can get easily inside the homes. so we make  system for home security purpose. But this system is very expensive and in this system we use a ring alarm to scare the thieves. But they do not actually inform you in immediate time that your house is being secure. When this system being completed its very expensive.

So I have an idea to make my own ring alarm which based on arduino. For this purpose I bought a GSM shield for Arduino Uno and other part I had.

 Parts Of GSM shields Home Alarm

 For this project you will need:-

Arduino Uno (Robomart);

GSM Shield (Robomart);

PIR sensor (Robomart);

An Arduino based buzzer (Robomart);

An alarm siren horn 12V(Robomart);

12V power supply (Robomart);

Relay module (Robomart);

Keypad for the Arduino (Robomart);

A box;

 

 

 

How to make connections

Firstly we have to place the Arduino Uno below the GSM shielded, then we solder  the two wires to GND and VCC jointly from two sensors, the buzzer and relay module input. After that we can connect the two wires on the connecter from GSM shield. After that we make a connection from input/output signals to this parts. And the last remaining thing is that we connect shield below the keypad.

It will be:-

 

 ArduinoUno / GSM shield pins:

·         Pin 0: not connected

·         Pin 1: not connected

·         Pin 2: not connected (the GSM will use this pin)

·         Pin 3:  not connected (the GSM will use this pin)

·         Pin 4: last row from keypad (keypad pin 4 – from 8);

·         Pin 5: not connected;

·         Pin 6: second column from keypad (keypad pin 6 – from 8);

·         Pin 7: third column from keypad (keypad pin 7 – from 8);

·         Pin 8: not connected (the GSM will use this pin);

·         Pin 9: not connected (the GSM will use this pin);

·         Pin 10: PIR sensor number 2 data;

·         Pin 11: siren horn signal (goes to the relay module input);

·         Pin 12: PIR sensor number 1 data;

·         Pin 13: buzzer signal input;

As it is possible to see, although the keypad has 8 pins, I just connected three (one row and two columns, allowing two numbers to be read – 1×2 matrix), because this way I can make passwords using these three wires, and there is no need to use all the pins from the keypad. This is because once the movement sensor detects a person walking inside the room, the person will have just 5 seconds to deactivate the alarm, so there is not enough time for the thief to figure out the alarm code. Once the alarm is not disabled on the given time, the GSM shield will proceed to send SMS to you, or to call your phone. The Arduino was programmed to call and once you answer the phone, it will finish the call. This way it will spare the credits from the mobile operator.

Of course, it is possible to get false readings from the sensor, or even the code can be buggy, so I put an option to disable the alarm just by sending an SMS text from my phone to the Arduino. Then we can send a message to show that this system will be correct.

 Conclusion of this system

After 5 sec you get a message or call in your phone when any thieves enter in your house after you can call police because I think you have much time to call the police.

When you receive the message after that the siren horn will alert the thieves and they will run without taking whatever they can. But if we do not use the siren then the thieves will not alert and they can catch by police. So by this system we can make our hose very secure.

If you have much better idea please suggest me so that I can improve my systems.
