I am an undergraduate student and full-time Emergency Medical Technician and I am trying to obtain a few basic measurements requiring the use of an accelerometer. What I require is a device that can measure acceleration of two directions, such as forward to rear acceleration and side to side forces as in a vehicle, or "sway". I would like a unit that is fairly simple to use, preferably one that would mount to the vehicle, where I could measure my data for a set period of time, then upload it to my laptop. I have spent quite a bit of time searching the internet, yet haven't been able to find a production unit that fits this description. Any help would be greatly appreciated!
