Application for Home Security

Project Requirements:

1. A switch that will be hooked up to the door to detect intrusion which will be connected to an 8051 microcontroller.
2. A GSM module for operation and give an update to the user about the intrusions and a buzzer installed in the home to alert other if an intrusion takes place.
3. ADK kit will be necessary that can be attached to your cell phone.
4. We will require Arduino microcontroller with ATmega2560 it has a USB host interface to connect Android phones to them so we will be requiring the Arduino Mega ADK which is derivative of Arduino Mega 2560.
5. MAX232 IC built in with the GSM modem will be required to operate the system the way we want.

Project Implementation:

The way this project will work is quite simple and so the first step will be to make a flowchart of the process to understand the flow of commands in the system based on which the system will be designed. So the working is actually quite simple when we think about it when the switch is triggered if interruption in detected it sends an update to 8051 microcontroller from which the 8051 signals the GSM modem to send the SMS to the user now the GSM modem Sends the SMS to the Android phone of the user now we have to give a delay time for 1 minute saying after receiving if the user replies in 5 minutes and will update the 8051 to either play the buzzer or not play the buzzer and if user doesn’t send the message android itself will send the SMS and sends a signal to 8051 to play the buzzer. The user if sees later it can override the command of play buzzer sent by Android.

Software requirements:

1. Arduino IDE:software used for dumping firmware that was created for the Arduino Board.
