TCRT5000L Reflective Optical Sensor with Transistor Output.

The TCRT5000L is a reflective sensor, consisting of an infrared led and a phototransistor in a leaded package.

Functionally the device consists of two parts, The Emitter (LED ) and the Detector ( phototransistor ). Light from the Emitter is reflected, from a nearby surface, back onto the phototransistor.  The amount of light reflected back, which is a function of the location, angle and reflectivity of the surface, determines the current that flows through the detector.

These are suitable for use as sensors in Line Following Robots.
