Working Principle -
The IR333-3C emits infrared light when forward biased current flows through the semiconductor junction. The emitted wavelength around 940nm is invisible to the human eye but is detected by IR receivers and photodiodes. The output intensity depends on forward current and is used in sensing and signal transmission systems.
