YRNGFND1 Yocto Range Finder


USB range finder sensor based on infra-red laser time-of-flight. This device can estimate distances to objects up to 1 or 2m, depending on conditions.

SKU: YRNGFND1 Categories: ,


The Swiss-made Yocto RangeFinder is similar in size as many of our USB sensors, such as the Yocto Altimeter: 20mm wide, 58mm long and just a few millimeters high. One could hardly guess that it encompass a tiny laser rangefinder for performing Time-of-Flight (ToF) distance measurements.

The ST Microelectronics VL53L0X rangefinder sensor embedded on the Yocto RangeFinder includes a 940nm infra-red VCSEL emitter, invisible to human eye, and an array of single-photon detectors. Given its size and price, this sensor is indeed impressive. Although it looks like a simple proximity sensor, it is actually capable of detecting objects up to 1 or 2 meters, depending on the conditions, and to provide a close estimate of the nearest object distance.

This sensor is however not magic, there are a few limitations:

  • 50cm away from the sensor, the sensing zone is 20cm wide
  • the max precision is 3%, inside and for clear targets
  • outside and for dark objects, you should rather count on an accuracy of 6%
  • the max range, inside and for clear targets, is 2m
  • outside and for dark objects, the max range is typically 70cm

The sensor part can be split and moved away using a 4-wire cable, to make it easier to integrate it in a machine for instance. Be careful if you intend to protect the sensor using a cover window: the measure could be affected by the window, and that might require an extra calibration step.
