IR Projector/Reflector

Hey guys,
I'm pretty new to Arduino, started working on a new project and would appreciate some help getting started.

I want to build a sensor that understands that a certain object is in it's field of view.
I thought of doing it using an IR beam on the sensor and a reflector on the object. (See picture 1)

If the object is within the sensor's field of view is, I get a TRUE message, if it's not, I get a FALSE message (See picture 2).

Any ideas/tips on how to start? Is it possible using Arduino hardware?
Thanks!

I have seen lots cool things you can do with a arduino but image recognition is not its general forte .

Now a raspberry PI seems much better suited for that.

I'm not talking about image recognition exactly, but something like recognizing if the object (with a reflector on it) enters the sensors FOV

Hi,
Welcome to the forum.

Modulated IR signal & appropriate receiver.

Most other objects will reflect IR much less than the reflector, so by setting the sensitivity of the receiver low enough you should be able to easily filter out most other reflections.

Thanks Tom and sorry for the mix up!

wvmarle - Have you heard of any similar projects that I can reference?
What type of hardware should I get for this?

Thanks

No - but I'm sure our friend Google has.
Look for break beam sensors. You're basically making a modified version of this.

What type of hardware should I get for this?

IR LED with appropriate current limiting resistor, receiver (TSOP type), reflector. Mr Google no doubt has specific suggestions.

What are planning to use as an IR reflector? A regular glass mirror will absorb the IR, not reflect it.
