Infrared light sensor with built in pulse driver circuit
and sync detector. Useful as a short-range wide-angle
proximity detector or for non-contact bump sensing.
The pulse driver modulates the output of an external
infrared LED (not included). The LED will illuminate
the target with modulated IR; reflected IR in sync
with the output is detected by the IS471F, making
detection relatively insensitive to ambient lighting.
You can purchase a matching high-intensity infrared LED
separately in our store. See
High-Intensity Infrared LED.
