I was planning on using an esp32 to measure suspension travel via a linear potentiometer. Due to the long runs of analogue wires needed at 3.3V and the noisy environment of the race car, even if I match the lengths of the cables to all 4 tyres, how do I ensure a clean signal and reliable data in a noisy environment.
Do I use nodes at each tyre with separate microcontroller then send all the data over CAN BUS to the central logger?
The issue then becomes a stable 3V power supply and a stable 5V power supply, since buck converters use switching they will induce noise, so the tricky part with this method is the power supply being a clean constant 3.3V and 5V.
Power Over Ethernet might be an option. I have not seen this on esp32 but you can probably find off the shelf solutions to that and it would reduce the wiring required to get everything working.
Adding to my previous post:
This device looks promising
