Framework

Hardware

Sensor Process

All sensors are connected to the mux which is connected to the Arduino. A string is created reading all temp sensors and accelerometer data along with the GPS lat, lon, alt, and time. The string is written to the SD card on the shield every X seconds.

Every Y minutes the position data is sent to the cell phone using AT commands to send a text message for back up tracking. This system could use something like Gumbands to process the incoming text messages and plot them. If that is used we need a webpage to handle the incoming messages and show the data, possibly with Google Maps integration.

Coding Standards

All tasks should be written as functions.

Pin assignments should be sent in the arguments of the function not hard coded. If possible, a separate "init" function should be used to set the pins once so that it is not necessary to pass the pin values to the "read" function with every call.

Functions should return either a string or numeric value.
