Real Infrasound Research on a budget
I have been working on a new geophysics project for the past two years, a compact infrasound monitor based on a digital, i2c enabled differential pressure sensor. Very open-ended with lots of opportunities for students of all levels - primary to postgrad - to redesign and test replacement components. This is also real science, in a little studied area. Well suited to networking in small or large areas.
This rig capable of resolving to better than 1 3-millionth of an atmosphere will cost less than £100 and provide plenty of valuable experience in computing, physics, electronics, and signal processing to a small team for a year or so.
Infrasound is a little studied area of geophysics/environmental science ripe for further investigation. The only U.K. detector I can find reference to is possibly one at Blacknest though little information is extant. A national network of home & school infrasound detectors could potentially generate useful scientific data as well as remarkable educational benefits.
The system stores raw data in the seismology standard .mseed format permitting easy analysis via ObsPy or other seismic software. Simple day plots of the signal and acoustic power are generated every few minutes for upload to some suitable website.
