hi guys,
i'm doing an eyeblink detector for our drowsy driver warning system, the project was done and very functional during night. but very sensitive at days especially at noon since the photodiode detects the light from the sun. how will i control the sensitivity of the photodiode from the sun. how will i modify the project as stable and functional even day and night and in any light situation. i already attached potentiometer at the sensor but still unstable esp at very expose places from the sun.
Attachment 70559
the led connected from rb0 represents the buzzer as the alrm indicator.
i really need ur opinions and suggestions.. thanx in advance,
