Project Changes

• Some novelty or underused functions have been removed from the project:• Automatic opening

• Bluetooth capabilities

• Changes were made based on a new addition to the project:• Mesh network of trashcans, monitored and maintained via

the web

Product Description

• The AutoCan is a network-enabled trashcan system.

• Force sensors notify users that the trashcan is full.

• Web-based interface to allow user to set date & time and an alarm.

• When trash can is full, user will be notified with a red LED.

Existing Products

• Honey-Can-Do Step Trash Cano $67.99

• Found in common households

• Hands-free, but still mechanical (stepper)

Existing Products

• iTouchless Trash Cano $129.99

• Uses IR sensorso Lid stays open for 3 sec.

• Battery-poweredo 4 D-batteries sold

separately

Product Name iTouchless Trash Can Honey-Can-Do Step Trash Can

Price $129.99 $67.99

Pros Automatically opens lid upon detection of a user

Hands-free, no power required to function

Cons Battery-powered (4 D-batteries sold separately), no user interface

User must open lid manually with stepper

How the AutoCan compares Neither option has the capability to monitor a network of trashcans and wirelessly set reminders or alerts to maintain them effectively.

Product Specifications

• The AutoCan will incorporate a user interface that consists of an Android application allowing the user to set alerts, disable alerts, and input up to five e-mail addresses for notification of an alert to notify the level of fullness of a trashcan.o Red LED will be lit until trash is emptied.o Status of the AutoCan will be relayed to the web

server to be accessed by the user. It can also be programmed to send an email as a notifcation.

Product Specifications

• Onboard systems maintains date, time, and alarm.o User can set date and time via the web.o User can set alarm via the web.

Interval (e.g. every 2 days) Date and time (e.g. 04/20/13 12:00)

• When user-specified alarm is triggered, red LED is lit.o Unlike the "trash full" alarm, this alarm is to be

disabled by the user.
