Parallax Laser Range Finder from Parallax

Picture of product

Click here for high res picture ...

the Parallax Laser Range Finder (LRF) Module is a distance-measuring instrument that uses laser technology to calculate the distance to a targeted object. The design uses a Propeller processor, CMOS camera, and laser diode to create a low-cost laser range finder. Distance to a targeted object is calculated by optical triangulation using simple trigonometry between the centroid of laser light, camera, and object.

Application Ideas:
  • Distance or liquid level measurements
  • Object detection and/or avoidance
  • Item counting
