A sensor control device and a sensor system are provided through which it is possible to automatically detect whether mutual interference occurs for a plurality of sensor units, and it is possible to automatically set periodic light projection timings for preventing mutual interference. A sensor control device includes a light projection control part configured to instruct a light projection operation for each of a plurality of sensor units and a light projection timing setting part configured to set periodic light projection timings when each of the sensor units is periodically operated based on results of light projection control for each of the sensor units and detection results of each of the sensor units.

Periodic light projecting sensor control device and sensor system ensuring mutual interference does not occur

A photosensor includes a light projection unit, a light receiving unit, a determination unit that determines a magnitude relation between a received light quantity of the light receiving unit and a threshold value set for the received light quantity; and a threshold value setting unit that sets the threshold value of the received light quantity. The threshold value setting unit calculates for each of a plurality of different wavelength regions, a contrast difference that is a difference between a received light quantity obtained when projection is performed on a detection target on a surface of a workpiece and a received light quantity obtained when projection is performed on a background on the surface of the workpiece, and updates the threshold value based on the contrast difference for a wavelength region among the plurality of wavelength regions in which the contrast difference has a maximum value.
