| Note 1: Effective range depends on object reflectivity and ambient lighting conditions. Note 2: Objects closer than the minimum distance can still be detected, but the measured distance might be inaccurate. The minimum detection distance is < 5 mm for the original (irs16a) short-range sensors and < 1 mm for everything else. |

The digital output versions just report if an object is within their detection range while the pulse width output versions report the actual measured distance to the object by encoding it as the width of a repeating digital pulse, similar to hobby servo control signals. The graphs below show some examples of the different possible output signals from the different Pololu Digital Distance Sensor versions.
