As someone who grew up in the state of Florida, the thought of earthquakes never really crossed my mind. Florida is not located near any tectonic plate boundaries so earthquakes very rarely occur… but it was a different story when I moved to Virginia. While Virginia isn’t exactly known for earthquakes, they do happen here.
Which brings me to this helpful little product on Tindie: the Earthquake sensor. The Earthquake sensor product is a breakout board based on the world’s smallest seismic sensor, the D7S. The D7S is a vibration sensor created by Omron and composed of a three-axis accelerometer. This board breaks out all of the important pins of the D7S into a 9-pin header. There are also three status LEDs on the breakout board, one for the power supply, and one for each of the INT1 and INT2 pins.
It’s an I²C device for connecting to Arduino or any other microcontroller. The SET pin can be connected to a button if you want to ability to click the the different functions of the sensor manually. The board is fully mounted, you only need to solder the pin header.
