Two PIR sensors in One Arduino(uno), But EACH PIR sensor has it's own function.

Is it possible?

I'm a Senior Student who's doing this for my research. Sadly, I don't have enough experience to solve this problem. I'm sorry but I still dont know much about the terminologies. So the answer that i'm looking for is only Yes or No. Well if you can help, then I would really appreciate it.

Yes

If you give each PIR t's input then yes. Just alternate reading both pins ans do what you want to do when the corresponding pin changes/goes high/goes low whatever.
