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, 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.


  • Compact module with integrated CMOS camera and laser system
  • Optimal measurement range of 6–48 inches (15–122 cm) with an accuracy error <5%, average 3%
  • Maximum object detection distance of ~8 feet (2.4 meters)
  • Range finding sample rate of 1Hz
  • Single row, 4-pin, 0.1” header for easy connection to a host system

Application Ideas:

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

Key Specifications:

  • Power requirements: 5 VDC @ 150 mA
  • Communication: Asynchronous serial; 300–115,200 baud with automatic baud rate detection
  • Dimensions: 3.95 x 1.55 x 0.67 in (10.05 x 3.95 x 1.7 cm)
  • Operating temperature: +32 to 122 °F (0 to +50 °C)
