Raspberry Pi seismograph project - Seismo Acoustic Monitor

Seismo Acoustic Monitor

The RS&BOOM combines all the features from the RS1D seismograph and the RBOOM infrasound monitor. It is a complete solution for monitoring the shakes of the Earth and the infrasonic booms in our atmosphere. Often the same source will produce both seismic signals, that resonate through the ground, and infrasonic waves, that travel through our atmosphere. With the RS&BOOM now you can record and explore the connection between these two data sets simultaneously.

The 1D, 3D, 4D and “Shake and Boom” have the same capabilities for detecting Earth motion in the vertical dimension. The 3D replicates these abilities in the horizontal dimensions, providing the user with a fuller view of earth motion in all 3 dimensions. The difference between the 1D and the 4D is that the 4D has a 3 dimensional accelerometer built into the board. This is interesting for people who live in earthquake zones where the strong motion might be enough to saturate the vertical sensor. With the accelerometer, the earth motion would remain on scale with the added benefit of being able to detect lateral motion as well.
