GridWatch

==========

GridWatch is a system for monitoring the state of the power grid using just

smart phones. Phones running the GridWatch application monitor their status

for power change events (when the phone goes from charging to not charging).

This transition could signal a power outage, but is likely just the user

unplugging his/her phone. To determine which, the phone checks the accelerometer

for motion (signifying the user is picking up the phone), and the microphone

for evidence of a 50/60 Hz signal emanating from the power grid. If neither

signal is detected, a power outage event is transmitted to a server. These

events are aggregated to detect a power outage.
