About this item:
The V5 Distance Sensor measures distance to an object, approximate object size and approach speed.  The distance measurement range is 20mm to 2,000mm.   Below 200mm the accuracy is approximately +/‐15mm, above 200mm the accuracy is approximately 5%. The approximate object size is reported as small, medium or large, and is useful for determining if the target is a wall or a game object.  Approach speed measures the approach speed of the sensor and the object.
 
The V5 Distance Sensor uses a classroom safe Class 1 Laser, similar to those used on modern cell phones for head detection.  The laser allows the sensor to have a very narrow field of view, so detection is always directly in front of the sensor.
