Acceleration and Impact Sensing with the Pi 3

Wed Sep 20, 2017 2:50 pm

I am looking at using a Raspberry Pi 3 to log data from a crash test dummy. The dummy will be launched on a bicycle at 20 km/h and then struck by a car moving at 30 km/h. My goal is to design a measurement and data logging system that can take in acceleration and force values from the crash at a very high rate so that the peak forces during the impact are recorded. I will then take this data and interpret it using MatLab.

So far I am looking at purchasing 4 tri-axial accelerometers (https://www.sparkfun.com/products/12803), and 8 flexiforce sensors (unsure on which to use right now) that will be placed inside and around the head of the dummy. I would need to convert the analog signals from these sensors to digital and I think that I could use this AD4000 chip (http://www.analog.com/en/products/analo ... d4000.html). Also, I think that I will need this clock (https://www.sparkfun.com/datasheets/Bre ... DS3234.pdf) in order to have a high enough sample rate, this should provide me with more than I need.

I have no experience with Raspberry Pi and I was curious if what I listed above would be possible? Any recommendations, or tips on what I should do would be greatly appreciated.
