I would use an Arduino to read 1 sensor on 1 pin to maybe fill an array at the tap of a button with timestamps showing state change times just to see if I get useful data.
If I didn't have a laptop to save those to then maybe I'd have them go to SD or EEPROM for later retrieval. Perhaps I'd think of a way to get speedometer data in there or just write that on paper.
You could have it read a pin and light up one of a row of leds to show data within different ranges. You don't have to be exact, just look for a suitable match to what you need.
What have you tested already? Do you need more complete or better data?
What can I say? I still don't know what this is for anyway.
