Designed in conjunction with Grand Idea Studio, 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, a CMOS camera, and a 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.
Warning: This is a Class IIIa laser product. Maximum output 3 mW @ 635 nm. Avoid direct eye exposure.
