Build the RS4D yourself with this DIY version! Just add your own Raspberry Pi computer board, ethernet and power cables. All the other hardware necessary to make your device is included.
Incorporating both velocity and acceleration sensors, the RS4D is an incredibly flexible seismograph. The multiple sensor technologies not only extends its usage applications, but also widens the range of motion it can detect.
The difference between the RS1D and the RS4D is that the RS4D has three orthogonally positioned microelectromechanical systems (MEMS) accelerometers built into the board. This is interesting for people who live in active earthquake zones where the strong motion might be enough to “saturate” the geophone velocity sensor, or in other words exceed the instrument’s measurement limit. With the incorporated accelerometer, seismic activity should remain on scale with the added benefit of being able to detect lateral motion as well.
The RS4D is a well-rounded, strong motion seismograph. With multiple sensors, more data options, and a wider range it has a multitude of applications, including those that require an accelerometer. If quakes are common where you live, keep an eye on the activity from the comfort of your own home, with your own personal RS4D earthquake monitor.
