The sensitivity control (SC) pin allows the minimum detection irradiance
threshold of the transceiver to be lowered when set to a logic HIGH.
Lowering the irradiance threshold increases the sensitivity to IR signals
and increases transmission range up to 3 m. However, setting the Pin SC
to logic HIGH also makes the transceiver more susceptible to transmission
errors, due to an increased sensitivity to fluorescent light disturbances.
It is recommended that the pin SC be set to logic LOW or left open, if
the increased range is not required or if the system will be operating
in bright ambient light.
