The next section discusses interfacing configuration with
general processor including the recommended signal
conditional circuitry.
The DET_A pin of HSDL-9100 is connected to the filter
circuit then to the comparator before interfacing with
the GPIO pin. The filter circuit is implement to provide
the ambient light filter. The PWM is pulse to drive the
LED_K pin alternative the external timer 555 can also be
replaced. The detector distance can be varies with the
increase/decrease of the LED current supply.
