Light actived switch - Kitronik 2112

A set for building anintensity-activatedtransistor switch, the switch is based onDarlington's circuitand a phototransistor responsible formeasuring light intensity.The module can operate in two modes, additionally regulated by a potentiometer, when the light intensity level exceeds a certain value and when the light intensity is below the selected value. The manufacturer has prepareddidactic notes, which contain information about the construction of the module, installation and soldering instructions.
