I'm trying to make a system that can take multiple sensor inputs from an Arduino connected through USB to a Raspberry Pi.

Is it possible to differentiate the different sensor inputs on the Pi so Serial.readline() can still be used? If not how else can I read the inputs on the Pi?

That is completely under your control.

Personally I would start each sensor message from the Arduino to the Pi with an identifier identifying the sensor.

  • So lets say i need all of the inputs at the same time, is there another way to differentiate it?
