The main aim of this Smart File Security System project is to design and development of a certificate folder tracking system. The tracking devices are GSM and GPS modules. The GSM and GPS tracking system are one of the modern accurate tracking devices. Our design comprises with the Arduino MC that controls whole the system.

These devices are used to locate the particular location of the objects such as lost certificate folder, identification of lost keys and send their coordinates to the user through an SMS. GSM digitizes and compresses the data, then sends the data to a channel in its own time slot. It operates at 1800 MHz frequency band. GPS receiver collects the information to calculate the user’s exact location.

The tracking devices are used to locate particular objects using GPS (Global Positioning System).The design consists of GSM and GPS system to track the location of the object. By arranging this tracking device in the objects like folders, briefcase etc. the user could track their location from time to time. This makes the user find his belongings within less time.

The design is done in such a way that the system could be arranged in less space and accurate in tracking locations. As there is a GSM slot in the design, the user could get coordinates of the object from time to time through SMS. The design consists of an alert system to find an object by the sound.

The size of the microcontroller can be decreased, and it can be arranged in the small objects. As this project is based on a microcontroller, GSM, and GPS. This project is developed with low cost by integrating GSM and GPS.

The system consists of different modules which are linked wirelessly with GSM modules. Cost effective SMS service of GSM network is used for transfer of data between the modules. This service provides the information about the location of the place, of the certificate folder.

Working operation of project

In this project we are using Arduino nano as microcontroller unit for reading and sending the data, We have GPS NEO 6M for getting the current location of module and this is interfaced to Arduino nano to pin 2 and pin 3, GPS NEO 6M will send the serial data in NEMA format to Arduino nano, and Arduino nano will take longitude and altitude values, whenever the GSM modem receives the message it is sent to Arduino nano and this will send the GPS location to sender (file owner).

GSM modem will be connected to Arduino nano to pin 0 and pin 1 RX and TX, Arduino nano and GSM SIM 800 and Arduino nano will communicate each other with AT Commands, GSM modem will have SIM card. We have small piezoelectric buzzer integrated into the file for easy identification of file with the sound indication.


• Certificate files.
• Property document files
• Other Important log data files etc…


This project is very useful as compared to existing file folders system which can track the file with small SMS with help of GPS system. This project can be further modified to IOT for more easy access with android application.
