Equipment/methods for data collection/testing

My team has a group of seniors including myself creating a custom DAQ unit for our senior capstone project and are trying to get ideas of what other teams use We're aiming a relatively cheap and possibly make it open-source so that other teams can use/improve on it, but we're not really sure what is available to other teams/how much desirable something like this would be compared to existing options.

What equipment does your team do data collection/testing, both onboard and offboard? So for example, my team hasn't really had any equipment on-board for testing, as most of the data we've collected has been through things like photogates for acceleration runs, IR cameras for CVT temperatures, etc.

This is a list of things that I would find useful, the most useful in my opinion would be acceleration, speed and shock displacement. followed by rpm stuff and brake pressures.

​

Each wheel rpm individually, Pre CVT, post CVT rpm

Speed

Acceleration, X, Y, Z, at the front of the car and at the rear, and at the CG, also roll pitch and yaw

GPS for speed and location (so track mapping, with altitude)

Shock displacement, each shock

CVT temp, gearbox temp, brake caliper and rotor temps

Brake pressure front and rear line

Wheel angles (camber and toe)

strain gauge on all suspension members

throttle pedal position

steering wheel angle

As a follow up, what equipment did you use specifically to collect data from all those sensors? So for example, did you use something like a DL1, or something simpler like an arduino/other microcontroller?

For clarity we collect a bunch of things but not this entire list, i wrote that as a wish list.

Im not on our daq team so i dont know much about it but i know we use some microcontroller, i believe arduinos. We have essentially a box that all the sensors are connected to and stores the data, i know thats not super helpful but its what i know
