Our goal is to take a design for a 'smart pebble, a road-health-monitoring device embedded in concrete, and optimize it for size and power consumption. The previous design is bulky and not ideal for the application; these 'pebbles' should be an inch or smaller in diameter, last a year, and be able to survive in the harsh environment of the concrete.
The devices should be able to communicate wirelessly (through the concrete) to one of many hub units which will be on the surface. These 'hubs' will communicate to the devices, specifying when to take data samples and when to send the hub all of the pebble's data.
On top of this, we will build an Android application which will communicate with the hub to retrieve the pebbles' data and tell the hub which duty cycle to tell the pebbles to use.
