I will show you how to build a sensitive earthquake detection system using the RasPi as a controller that both processes and displays the signals generated by the detector.
Let us begin with a discussion of seismology and earthquakes, focusing on their makeup and how they are measured. Seismology is the term used to describe the study of earthquakes. This background section will help you understand the key concepts behind the detection-system design and what you should realistically expect from this fairly simple system.
I have also included a section on the analog-to-digital conversion that is needed to allow the RasPi to link to the earthquake, or more generally termed, seismic detector.
Some sample ...
