After my first successful attempt to make a seismometer |
|
(TC1 seismometer on my previous video), I decided to make |
|
another more complex and more precise seismometer |
|
aspiring as AS1 Seismic System. |
|
|
|
I used the same electronics and processing software as my |
|
previous seismometer, but the results I received are |
|
incomparable with the previous ones. |
|
This seismometer is far more sensitive and highly |
|
resistant to unwanted noise. Since at the moment I did |
|
not have a low noise operation amplifier, the input stage |
|
after the sensor I made with LM741 IC . For D-A converter |
|
I use Arduino Nano. |
|
|
|
After several days of waiting, I registered several |
|
smaller earthquakes, one of which is with a magnitude |
|
less than 1 Richtter.As you see from the images, I |
|
compared the results of my seismometer with the results |
|
from the local seismological station in my city of Ohrid |
|
which proves that the sensitivity of my seismometer is |
|
the same and even better than professional seismometers |
|
at least when it comes to measuring local earthquakes |
|
|
|
As I said earlier, I developed this model based on the |
|
instructions given on the web site: |
|
http://www.jclahr.com/science/psn/as1/, and I made |
|
several improvements. |
|
Instead of dumping oil, I used a magnetic system from an |
|
old hard drive, from which I also used magnetics with |
|
high magnetic flux to induce a current in the coil sensor |
|
This is a seismometer with a low oscillation period in my |
|
case 1/2 second and is intended exclusively for |
|
registering local earthquakes |
|
