Apply the output control circuit of the photodetector. The voltage dividing points of RI and R2 can set the threshold level. The distance between the
light- emitting diode
and the phototransistor of this circuit can be in the range of 0-5 mm, and the direct light or reflected light can be detected.
Change the state of light and no light (or light blocking ) into an electrical signal output, and add it to the load RL.
