Arduino Seismic Activity Monitor
This Seismic Activity Monitor is built based on Arduino and Ethernet Shield. It can be used to hook up a seismic sensor to a router through the Ethernet shield. All the data for the seismic sensor is stored in a Pachube feed and then displayed on the webpage as several graphs. A Piezo Film vibra-tab sensor is used to capture seismic vibrations.
