Smart Personal Money Vault Monitoring System Based on IoT

Introduction

Banks and other financial industries uses modern technologies for monitoring the money vault. Vault is one type of room or big container which contains valuable items. Industrials vaults are uses several layer of security system. On the otherhand, the security level of personal vault is poor due to the huge maintenance cost. In this project, we are presenting a low cost smart personal vault monitoring system based on Internet of things. By using this system user can able to monitor the status of the (closed/opened) via cloud connected mobile apps.

In this project, we are presenting a low cost smart personal vault monitoring system based on Internet of things. By using this system user can able to monitor the status of the (closed/opened) via cloud connected mobile apps. The block diagram of the system is shown below:

Necessary Things

• Infineon 3D magnetic sensor

• IoT development board (Arduino Yun)

• Internet connectivity

• Smartphone

• Application development knowledge

Building the System

• Connected the 3D magnetic sensor with IoT development board via IIC protocol.

• Connected the indication LED with the system (optional).

• Flashing the firmware to the development board (The firmware are available on code section).

• Connect the Arduino Yun with WiFi network.(nicely describe on https://www.arduino.cc/en/Guide/ArduinoYun)

The circuit diagram of the system are also available on diagram section.

The firmware flashing process is describe bellow:

• Download the source code from Git repository.

• Download and install the necessary libraries from Git repo as well.

• Open the source code using Arduino IDE. (A little modification is needed for connecting the board to the IoT cloud. Refer the thinger.io documentation for details).

• Connect the Yun board with PC via USB cable.

• Compile and upload the code by clicking compile and upload button respectively.

Thinger.io IoT cloud platform is used here for building the project. An account is mandatory for connecting the device with thinger.io. please refer the thinger.io documentation section for more details about device connectivity and others.

We have also developed a mobile application for remotely monitoring the vault status. The application is directly connected with iot-cloud and it visualizes the real-time information of personal vault. Refer the demonstration section for more details.

***The APK file is available in my git repository.

Demo

The possible application domain of this system are, financial industries, smart home, industrial automation, etc.
