Or do you just want some warning, a few seconds that could save your life.
This project will allow you to hook up a seismic sensor to a router through the Ethernet shield and host a webpage off of the SD card on the shield. This webpage will then display information about the seismic sensor and the history of its activity.
All the data for the seismic sensor is stored in a Pachube feed and then displayed on the webpage as several graphs.
You will need:
- Preferably an Arduino with large memory, I used the Arduino Mega 2560
- You can use one with less memory, you just might have to remove some stuff from the sketch
- Ethernet Shield
- Micro SD Card
- Pachube account:
- Piezoelectric Sensor
- Resistors, Capacitors, Diode
- Check the section on building the circuit for more details on values
- 5 x Op-Amps - Single-supply compatible
- or you can build it with dual supplies, whatever floats your boat :p
- You can get away with using only 3 - 4 op amps, the rest I use is for amplification
- Solid Wire of course!
I assume you already have:
- Would be pretty magical to surf the net without these
- Extra Ethernet cable
- USB cable for the arduino
- Un-destroyed analog pin on your arduino
