Abstract:
To avoid cell phone theft, this indicator is used. While theft, this cell phone automatically sends SMS to our familiar cell phone number.

Description:
By our careless or unfortunately some time our cell phone thefts. It makes big problem to many ways like we are loss several contract numbers and also we are loss our money. So avoid this situation we are designed and developed this cell phone theft identification project. By using our concept, we can easily identify the theft person. Now we are developed the demo level project by using GSM module and Microcontroller. We are not able to reprogram the cell phone for that we are used GSM module and Microcontroller.

Whenever switched ON the cell phone, at the same time it will checks the SIM number with previous SIM number. If it is not matching means it will send SMS to particular cell phone (our believing person cell) and also after change the SIM the theft person can be call some cell phone. These cell numbers is also sent to our believing person cell.

3. Introduction

Brief explanation of project:
In this fast moving world, each one required cell phone. The cell phone use is unavoidable for each businessman, workers, VIPs, government employees, etc., So for the cell phone development is improving day by day. But our careless or unfortunately some time cell phone thefts. So avoid this cell phone theft we are designed and developed this cell phone theft identification project. By using our concept, we can easily identify the theft person. Now we are developed the demo level project by using GSM module and Microcontroller. We are not able to reprogram the cell phone for that we are used GSM module and Microcontroller. Here we are explaining briefly about our concept. If the cell phone is thefted means, the theft person is suddenly changed SIM card. While changing the SIM, the instrument power is restarted. Taking this advantage we are proving our concept. While restarting the Microcontroller it will first check the SIM number. If the SIM number is changed means the Microcontroller is send SMS to our peculiar person cell phone. And also it will send the incoming and outgoing calls details.Hear we are using the GSM module instead of cell phone for our demo purpose. The GSM module does all the works of which will be doing the cell phone. For interfacing, the serial port output is available in this GSM module. So we are easily interface GSM module with the Microcontroller. The communication between GSM modules to micro controller is serial port communication. The serial port output of the GSM module is in the form of RS 232 logic because it can able to communicate 20 feet’s. But the micro controller work under TTL logic. For that the serial port output RS 232 is converts into TTL logic with help of Max 232 IC. Than the converted TTL logic is given into micro controller. For activate GSM module we required 2 AT commands. They are 1. Sending massage

2. Receiving massage
And than we required some more commands they are.
1. For SIM number reading
2....
