How think about second-hand smartphone integrate to food computer?


I’m KwangHee Han. I make food computer in South Korea.

Since 2weeks ago, I tried develop android application for second-hand smartphone to our food computer.
In this time, Android application development is my first time. But I expect this smartphone take a role what take a picture and analyze image using openCV library and collect data from sensors.

In my opinion i can use some sensors like Light indensity, proximation, Gravity, GPS and gyroscope.

How think about using smartphone in the food comptuer?
