can sensors controlled using one arduino input pin?

Hi, I was trying the parking system project and have some missing theories. Is it possible to control or sense the result of sensors (maybe 5?) with one Arduino input digital pin? Sensing in the way that whether the sensor is high or low. If do so can you explain whether it is on the coding part or the hardware part, or some brief information on it. Thanks in advance. :)

If you don't care which of the sensors was responsible for setting the pin HIGH (or LOW), yes. Assuming that the sensors are otherwise correctly wired.

If you do care which sensor set the pin HIGH or LOW, then, no, you can't.

Without knowing the electrical characteristics of the sensors, I don't see any way to answer this question.
