【IR Break Beam Sensor】is the abbreviation of photoelectric proximity switch, which uses the beam of light of the detected object Occlusion or reflection is controlled by a synchronous circuit to detect the presence or absence of objects. Objects are not limited to metals,All reflective objects can be detected, with high sensitivity, fast response speed and good stability Faster than PIR sensors for better control of where you want to detect motion
【Note】That is, the red wire is connected to the positive electrode, the black wire is grounded, and the yellow (white) wire is connected to the signal. Add 1K pull-up resistor between the positive electrode and the signal to directly connect to the microcontroller I0 port
