RF Proximity Sensor

I need a RF proximity sensor for my graduation project of at least 18m detectable range, Are there any kits I can get? or does anyone has any schematic for any WORKING relevant circuits?

Xband is a good method for RF motion detection. Parallax has one, I have not looked to see if sparkfun has something similar.

First, Thank u for consideration and replying, the Xband I found on Parallax is only 9m+ and I didn’t find it in sparkfun. Did you know some relevant stuff that may be more than that range (18m+)?

Thank you again for replying! :slight_smile:

With RF? No. Maybe look up Kband motion detector.

By “proximity” do you mean present/absent within 18m? Would this always be line of sight?

Have you studied the inverse square law in RF propagation, and the effect of frequency on this?

For your school assignment, you want a schematic and a working circuit?

Thank you again for replying! OK, no problem if its not a RF one, are there any object detection sensors of detection range 18m+ and if yes, where can I find it?
