Reflective sensors are used in industrial automation. A special application of reflective sensors are linefollower robots that follow a line painted on a given surface (e.g. the floor). The operation of reflective sensors is based on the phenomenon of interrupting the light flux that is sent from the sensor and then reflected by the reflector. Depending on the specific type of reflectance sensor, these electronic components use light that is invisible to the human eye (e.g. ultraviolet or infrared rays) or visible light. A common feature of reflective sensors is the transmitter and receiver enclosed in one housing. The state in which the light stream is interrupted changes the signal output from the sensor.

Reflective sensors are used, among others, in industrial automation. They are installed in linefollower robots, whose main task is to follow a painted line (e.g. on a warehouse floor). The principle of operation of reflectivity sensors is to emit light and reflect it using a reflector. When the light stream is interrupted, the signal changes.
