The sensor sends a beam of radiation through the IR transmitter, then measures the intensity of the light reflected through the phototransistor. The output is a voltage signal dependent on the light intensity falling on the detector. The more light will be reflected and get to the photodetector, the higher will be the output voltage. As the light is reflected better by the bright surface (dark surface absorbs it), the voltage will be higher on white material.
The sensors are readily used by designers of Line Follower robots to detect lines, as well as in the mini-sumo construction where it is used to detect the edges of the ring. As, in these cases, detected are the extreme values (to distinguish black from white - intermediate values are not important), the sensor can be located higher above the surface than the documentation indicates. From our experience, we can tell that with an appropriate selection of resistors, sensors correctly distinguish the black insulating tape from the white background from a distance of about 1 cm.
In the industry, the systems can be used, for example, for edge detection or detection of objects at close range. The sensor has easy to install through the hole in the case. In addition, installed is the protection rim that allows you to completely squeeze the detector and transmit to the surface.
