I'm working on a prototype for a cheap launch monitor as a cheap alternative to the expensive ones on the market atm.


I'm looking for a sensor or sensors that can track the following

  • High-speed objects ~250mph
  • Small objects (golf ball)
  • Direction left, right, and up
  • Preferably a relatively cheap solution (100-200usd)

Which type should I use for that project?

This is what I have found until now:

I have found the OmniPreSense but I'm also looking for alternatives and there is a drawback it seems to not be able to track speeds in excess of 138mph.

Would also be amazing to get feedback from someone that has tried a similar project that I can spare with.

    The sensors you linked to can handle much higher speeds (over 300 mph) but have limited range (tens of meters), and I doubt they would be able to track something as small as a golf ball, even less at higher distances. Tracking a golf ball is a hard problem, I doubt you’ll find a cheap and effective solution, but you’ll first need to narrow down the type of sensor you want to achieve this.

  • I figured out i need a 3D doppler radar sensor i dont need full ball flight if i have direction and speed the rest can be calculated Jan 11 '21 at 0:08
  • @jsotola I updated the question :) Jan 11 '21 at 13:48
  • @SimonDragsbæk something went wrong ... the question shows no edits
