I would like a field deployable data acquisition system (preferably using something simple like arduino) that will record a fluxgate magnetometer for days in the open air.
If you want to look it up, this will be used for geophysics, one use will be to be a base magnetometer, which will remove for the magnetic changes due to solar storms and the second will be to record magnetotellurics, which can measure the conductivity of the earth, kilometres beneath the earth.
I would like someone to produce a working unit, which means, buy all of the components, assemble them, connect it all up, house it, so that its protected from weather. I’ll supply a 12v lead acid battery (12V 5Ah sealed lead acid) and the solar panel and connectors between the solar panel and battery. I’d like everything except the solar panel in one contained box. A two meter lead for both the magnetometer and temperature sensor need to run outside the box. The box doesn’t need to be to any water rating, so running the wires through a grommet on the side of the box is fine.
I don’t want any display or any functionality, no header on the file, it should just be the battery is connected and it starts acquiring and writing data. If the first couple of minutes takes a while to get in sync with the GPS that’s fine.
18 bit ADC for magnetometer, 3 channels, [login to view URL]
Note the voltage inputs for the magnetometer, I would also like you to produce the magnetometer connector please.
Recording at 1hz.
GPS timing, I would like to output the UTC date and time to the nearest second.
Temperature sensor, doesn’t need to be overly accurate, to the nearest degree, 0.1deg resolution.
Log data onto an sd card.
The output data needs to be sorted into columns (either tab or comma seperated) so that I can read it into my software.
The DAS will be deployed to really remote areas, so it needs to be dampened from vibration during the drive out there.
I would like one produced, I’ll test it and if it all works well, I’ll ask you to make another one, so please quote the cost to build both one unit only and two units.
