Welcome to The Inexpensive Seismometer Project,
an attempt reduce the cost and complexity of amateur
This page is about my project to build simpler and less expensive amateur short period seismometers by using microprocessors and other new chips, such as switched capacitor filters. Short period seismometers are useful for detecting and analyzing local seismic activity (within a few hundred miles or closer). For more general information on other types of seismometers and links to web resources, see my main seismometer page. Click here for information on my long period system.
December 2015 QM accelerometer system status:
Now shipping ADXL203 sensor based systems worldwide!
See for latest updates to this page.
The QM-ADXL203-20HZ strong-motion, single-board, single-channel accelerometer design:
OPTIONS: Options include a longer additional serial (DB9 M/F) extension cable if your PC will be a long distance from the sensor. The QM-ADXL203-20HZ has a built-in serial cable that is 15 ft long. We have some serial extension cables that are 10 ft ($10), 25 ft ($20), 50 ft ($30), and 100 ft ($50) long.
MAIL ORDERS: We are now buidling QM-ADXL203H-20HZ and QM-ADXL203V-20HZ strong motion seismometer that is ready to run with the free Amaseis computer software.
