I am an occupational therapy student an I need help with electronics. Can I connect an IR sensor to a buzzer without using an Arduino? If yes, can I have any suggestions? Thanks in advance.

It is a very small adjustable IR sensor. It's not for a home. It's so that someone can be notified of proximal object on their blind side if that makes sense.

So you need a proximity sensor, not an IR beam interruption sensor? Passive IR (PIR) sensors detect movement of thermal objects (like people), but they aren't necessarily used for proximity sensing. Often ultrasound echoes are used for proximity sensing in close. Can you elaborate on what kind of objects you want to sense and how close they will be?
