Patent attributes
A process circuit sets a plurality of light emitting elements in a state in which light is not emitted through a process circuit, and receives a signal S1 corresponding to received ambient light from each of a plurality of light receiving elements. The process circuit generates light receiving information (data DT) showing the light receiving state of the ambient light with respect to each predetermined number of light receiving elements among the plurality of light receiving elements. The process circuit transmits the data DT to the outside. The personal computer receives the data DT through a communication unit and displays it. In a sensor SNS, the amount of light received can be displayed with respect to each optical axis by the personal computer. Thus, an operator can find the light receiving state of the ambient light in more detail than the conventional sensor.
