Budget Infrasound Monitor -- New for 2017
I have been working on a new geophysics project for the past few months a compact infrasound monitor based on a digital, i2c enabled diferential pressure sensor. As a taster I feel this is a beauty. 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. Oh - and cheap! see Blog (above) for current status
System currently offline pending rebuild
22/8/17 - taken offline for rebuild and photographing for write-up. Should be back online within 7 days.
One will immediately observe that the real-time feeds lack vertical scales - due to a problem with the Obspy plotting package running on a Raspberry Pi. These are generalted on the fly by the Pi used to monitor the sensor. and should be used for quick observation of output. The idea being that the data be downloaded from the PI for more detailed analysis. I have written a general analysis tool in python for this - examples below.
Presently I am testing kit before seeking university involvement. I will post more details by the summer of 2017.
