Optical Distance Sensor

The Optical Distance Sensor, or ODS, detects changes in the distance from a target surface using pulsed light.
SKU: 45-2006

The Optical Distance Sensor uses a pulsed light signal to return a value representing the distance from a target surface.  As the distance from the target changes the returned value changes indicating whether the movement is towards the target or away from the target.

The ODS operates by pulsing an LED to illuminate the target surface and measuring the strength of the reflected signal. The returned value will vary for the same distance as the reflectivity of the target surface varies.
