INTRODUCTION TO SMART BAG

Smart Bag is an application specific IOT based design. It is an intelligent bag with various features including :

· Device charging - Allowing you to charge your mobile devices

· GPS tracking - Weigh the bag just by picking it up and track it both by proximity and by GPS location

· Electronic Locks - Control TSA-approved locks from your smartphone

· Remote, app-enabled controls

· Bluetooth connectivity

· Wi-Fi connectivity – Portable Wi-Fi hotspots, in case you find yourself in an area where you can't get connected.

· Electronic scales

· solar recharging capabilities

· RFID-blocking liners to prevent identity theft

MOTIVATION OF THE PROJECT

Theft or loss of baggage or luggage at various public places including railway stations, airports or other areas is a unexpected circumstances which may happen with anyone at anytime. When lost , locating it is a very difficult , nearly impossible task . Therefore , involving the feature of GPS tracking with the help of an android app will be a revolution in this aspect. Also according to the directives issued by Ministry of Human Resource Development (MHRD) the weight limit for the school bags of students should not exceed to 2 kg to 3 kg. Also , in the metro stations (for example in Delhi Metro stations) or at airports the weight limit of baggage should not exceed to 15 kg of weight. Therefore , a feature to calculate the weight measurement of the bag automatically with the in front display of the measured bag will help the people to not exceed the limit and abide by the rules . Also it will prevent the time that is elapsed at the weight checking counters and also it is cumbersome for travellers at various stations to remove their belongings there so s to abide with the weight limit which they were initially unaware of the weight of their bag so that they can prevent such situation. In this todays world of Intelligence , smart technologies are at a hype . IoT is the hot topic at present in terms of smart technology including Smart City , Smart Homes , Smart Vehicles etc . IoT , Internet of Things is a network of interconnected things , people and various other electronic components with the sensors which senses the environmental conditions send to the remote controller at remote locations which accordingly make the other components operate with or without human interaction. Thus, IoT plays a key role in the technological advancement in the world.

PROPOSED SYSTEM

The proposed system for the Smart Bag project includes the IoT technology to track the bag and measure the weight. The hardware components includes a Load Cell and a HX711 module to measure the weight with a microcontroller i.e., Arduino Uno and a 16x2 LCD (Liquid Crystal Display) to display the weight measured.

For tracking the location , GPS module is used with a microcontroller i.e., Node MCU -1.0 . The location information is transferred to the server and to the android application which will get the position information from GPS module and further will display its position on a google map which will be navigable i.e., can be tracked.

ADVANTAGES--

1. Luggage Tracking - Anyone who has ever had a bag lost or stolen will appreciate the ability to track a bag as it travels through the network of airports, or any public places. (and beyond).

2. Built-In Scale -  The app tells you approximately how much it weighs. Sounds convenient (especially if, like me, you pack to the max) but if the bag’s scale is less accurate than the airline’s, you could be in trouble.

3. Integrated Screen – Bag consists of integrated screen which displays the weight measurement.

APPLICATIONS--

1. Painting/Artwork Security:  With a GPS device owners can quickly learn the location of a stolen piece and recover it immediately.

2. Police & Private Detectives: Police can benefit by attaching tracking devices to baggage during investigations, allowing them to easily track movement and come up with solid evidence.

Hiking: With a GPS device, hikers who get lost can be recovered quickly should they ever come up missing
