I am a technical technician for Laser machines and we have tested some samples of sensors

I could not load the photos on the site.
The measurement of friends is completely correct and finally if you can convert the frequency to analog voltage it will probably be easier to control
The main problem in using this sensor is not reading the output, but keeping the distance constant.

Hello Masi,
Have you already created a cicruit or device to convert the frequency signal to 0-10V or 4-20mA converter? This would make it a lot easier to control the height.

Why would you not read the frequency directly,
as that would be faster and more accurate?
