DIY Extremly Sensitive and cheap Geophone sensor for Earthquakes detecting
This project is sponsored by PCBWAY https://www.pcbway.com/?from=MirkoP
Only $30 for an SMT prototype order. Free shipping & free stencil.
A Geophone is a device used to detect and measure ground movement or seismic vibrations. This time I will describe to you how to make such a sensor yourself for free from parts that can be found in any workshop. However, the sensitivity does not lag behind commercial geophones at all. Even this sensor reacts to shocks in all possible directions which makes it incredibly practical, In other words, it replaces many different types of Geophones.
This sensor is conceived as part of the final project, which will actually be a stand-alone seismometer and will display the relative intensity of the earthquake at the point of detection. In the next video that I will promote soon, will be described the electronic part consisting of an amplifier, filter, A/D converter and PC software. Thus we will get a complete extremely cheap and sensitive home seismometer.
