Arrange several FC-51 sensors across a hallway. When a player breaks an IR beam (by walking through), a buzzer sounds or a counter increments. It’s a family-friendly alternative to laser tag for birthday parties.
Provides a simple HIGH or LOW signal (using the LM393 Comparator IC ) indicating the presence of an object. fc 51 ir sensor datasheet hot
