Photoelectric detection output control circuit
Shown is the application of photoelectric detection output control circuit . The voltage dividing points of RI and Rz can be set as threshold levels.
The distance between the light-emitting diode and the phototransistor of this circuit can be in the range of 0-5 mm, and the incident 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.
