At-home Earthquake Damage Assessment

This is an at home device to assess damage done to your home while you are not there.

You will need:

1 Intel Edison board

2 Seeed Base board

3 Seeed dust sensor

4 Seeed Gas sensor

5 Seeed water sensor

6 Seeed temperature sensor

7 Seeed flame sensor

8 AT&T M2X account (Free)

Follow the instructions on this link https://software.intel.com/en-us/assembling-intel-edison-board-with-arduino-expansion-board

follow the simple instructions here https://m2x.att.com/developer/get-started

Plug dust sensor into D4

Plug gas sensor into A0

Plug temperature into A1

Plug vibration sensor into A3

Plug water sensor into D2

Plug flame sensor into D5

Copy this code into your arduino IDE, then run and you are ready to go!

Be sure to add your own wifi and api keys
