Parallax Laser Range Finder

Description

Designed in conjunction with Grand Idea Studio (www.grandideastudio.com), 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 multicore Propeller microcontroller, 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.

Features:

Optimal measurement range of 6–48 inches (15–122 cm) with an accuracy error <5%, average 3%

Maximum object detection distance of ~8 feet (2.54 meters)

Range finding sample rate of 5 Hz

Compact module with integrated CMOS camera and laser diode

Single row, 4-pin, 0.1” header for easy connection to a host system
