Can I Connect an IR Sensor to a Buzzer for Proximity Alerts Without Arduino?

[Alexander Lopes]

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.

Not directly. Try a search: https://www.google.com/search?&q=door+annunciators

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.

A search for "ir proximity sample circuit" returns several examples.

Here's one example http://www.instructables.com/id/A-very-simple-proximity-detector/

You don't need extensive electronics skills, but you need the basics if you are going to continue in that field.

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?
