In my system, I have a liquid level sensor that outputs= 5V 50 Hz PWM 0% - 1100us 100% - 1900us.
I have a rpi zero as the center of my system, and I need to feed this information to it, so it can trigger commands. I have a weight limit, so I was thinking of inputting the liquid level sensor to arduino atto, get the percentage value and send to rpi via I2C
