  This study presents a system that combines a conventional refrigerator,
microcontrollers and a smart phone to create an inventory monitoring that can
monitor the stocks inside the refrigerator wirelessly by accessing an Android
application. The developed refrigerator uses a sensor network system that is
installed in a respective compartment inside the refrigerator. Each sensor will
transmit data to the microcontrollers, such as Arduino Yun and Arduino Uno,
which are interconnected by the I2C communications. All data and images will be
processed to provide the user an Internet of Things application through the
cloud-based website Temboo. Temboo will have access to send data to the
Dropbox. A smartphone is connected to the Dropbox where all the data and images
are stored. The user can monitor the stocks or contents of the refrigerator
wirelessly using an Android Application.
