Is there microwave motion detector that can be a tachometer?

Hello,

I am looking for a microwave motion detector that also has to be a tachometer. Every time the movement is registered detector records it as 1 movement. The area detector covers needs to be narrowed down. In my case, I am looking for something like 2 inch by 4-5 inch area. The detection distance from the sensor should not be more than 1 meter.
Initially, I thought about using laser no contact tachometer but it does require reflective tape. Applying reflective tape will not work for what I need. Basically, microwave motion tachometer I am looking for needs to work as a laser no contact tachometer but without reflective tape. Also, the MPS (movement per second) will not be more than 20; so, laser is not necessary.

Please, let me know if it is feasible and actually exists.

Thank you.

Welcome to the forums.

A little vague on what you are doing.

microwave motion tachometer
That would mean you want to use some type of microwave sensor to measure speed ?

Are you counting product like on an assembly line ?
Are you trying to see how fast something is moving in a straight line ?

Maybe with a more precise explanation we can help you better.

I suggest you investigate infrared proximity sensors. For example: Sharp GP2Y0A02YK0F.

You would have to connect it to a counter to perform the rate calculation, but the sensor should do what you want without any reflective tape or the like.

Thank you. Will do a research on it.

Thank you.

Basically, I need a sensor that would be a tachometer counting how many times an object passes through the imaginative line (sensor line). Yes, I am trying to see how fast an an object is moving through the imaginative line; conclusively, that would be a speed. (crosses through the line/minute).
