# Item-Tracking Backpack

# Problem

Many people use backpacks to store their belongings when going out. Since backpacks can hold many items, it can be easy to lose track of what has been put in it. The act of checking the bag to ensure nothing has been forgotten can often be inconvenient. This becomes especially time-consuming when many items have been placed in the backpack. Keeping track of where each item has been placed can also be a hassle for smaller items or when there is a large number of items in the bag.

# Solution

A system for monitoring the items present in the backpack using RFID can be implemented as a solution. Users can input the items they plan on placing in the bag using a phone application. RFID tags can be placed on these items, and once all of the items listed have been detected, a green LED will light up to indicate that nothing has been forgotten. Moreover, to assist with keeping track of the items within the bag, the user will be able to specify where a specific item will be placed. A red LED will light up to indicate that a compartment does not contain the exact items desired.

# Solution Components

## Subsystem 1: Sensors

This subsystem will deal with detecting the items present in the bag. RFID will be used to monitor each individual item present.

## Substyem 2: Microcontroller

The microcontroller will interface with the RFID sensors to determine which items are present, and whether all items have been placed. It will turn on the green LED and turn off the red LEDs when all items are present.

## Subystem 3: Indication

A 10 mm green LED will be used to indicate if all the items the user was planning on placing in the backpack are present. The LED will light up once the RFID has detected all the desired items to inform the user that nothing has been forgotten. A 10 mm red LED will be used for each compartment, and it will light up if the RFID could not detect a desired item in the compartment.

## Subsystem 4: Application

The application will allow users to create a list of items to be placed in the backpack. Items can be added and removed from the list and any items missing will be displayed. The application will also allow for the organization of the items in the bag by allowing the user to add items to a given compartment.



# Criterion for Success

Green LED lights up when all the desired items have been placed, otherwise, it is off

Red LEDs light up if items are missing from a given compartment

Two compartments capable of storing large items properly track the items contained in it

One compartment capable of storing small items properly tracks the items contained within it

The application allows for the list of items to be placed in the backpack to be changed

The application allows for the organization of the items to be placed in different compartments

The application recommends missing items or items placed in an incorrect compartment

Featured Project

There is a drastic lack of networking infrastructure in unstable or remote areas, where businesses don’t think they can reliably recoup the large initial cost of construction. Our goal is to bring the internet to these areas. We will use a network of extremely affordable (<$20, made possible by IoT technology) solar-powered nodes that communicate via Wi-Fi with one another and personal devices, donated through organizations such as OLPC, creating an intranet. Each node covers an area approximately 600-800ft in every direction with 4MB/s access and 16GB of cached data, saving valuable bandwidth. Internal communication applications will be provided, minimizing expensive and slow global internet connections. Several solutions exist, but all have failed due to costs of over $200/node or the lack of networking capability.

To connect to the internet at large, a more powerful “server” may be added. This server hooks into the network like other nodes, but contains a cellular connection to connect to the global internet. Any device on the network will be able to access the web via the server’s connection, effectively spreading the cost of a single cellular data plan (which is too expensive for individuals in rural areas). The server also contains a continually-updated several-terabyte cache of educational data and programs, such as Wikipedia and Project Gutenberg. This data gives students and educators high-speed access to resources. Working in harmony, these two components foster economic growth and education, while significantly reducing the costs of adding future infrastructure.
