Hi there! I am looking for a datalogging device that is small (Arduino Uno/ Nano size), automotive grade, and can store PWM input into a microSD card.
I am trying to read and store PWM data from a fuel level sensor.
Does anyone have any ideas? Any help would be greatly appreciated!

PermalinkHi Ivan, if you are trying to do it with arduino it is pretty easy. You just have to use an SD card module and interface it with Arduino. If you need time and date then you might also need a RTC module. Refer the below project for an idea

You can ignore plotting values on Excel and just store them in SD card. I am not sure what you mean by PWM data. If your sensor is providing PWM signal as output then you have to measure the frequency and duty cycle of the PWM signal and plot them. What sensor are you using do you have a datasheet on it?
Also I am not sure if Arduino is automative grade, so you might have to check on that
