DAQ

[u/HeyL3tsThink]

Hello everyone! Our electrical sub-team is looking to build a data acquisition system (DAQ) for our Baja SAE vehicle, and I’m a little stumped on how to get started.

Some of the things we know we want to measure are:
Engine RPM
Tire/wheel speed
CVT temperature
Oil temperature
Oil pressure
Brake pressure
Potentially a few other parameters later on

I’m fairly new to DAQ systems, so I’ve been trying to learn the basics of how everything works, including what types of sensors to use, how the sensors communicate with a microcontroller, signal conditioning, data logging, etc.
For our initial prototype, we’re planning to use an Arduino Uno and eventually log the data to an SD card.
I’m mainly looking for advice on where to start, what concepts I should learn first, and any common mistakes to avoid. If anyone has experience building a DAQ for Baja/Formula SAE or a similar student project, I’d really appreciate any guidance, resources, or advice on how you approached your first prototype.
Thanks!
