Dear All,
I'm planning to build some intelligence in my car lights and I need your advice on recognizing ambient light intensity. I've already build DLR control in my car using PIC12F683 which is Mercedes style dimming for the DRL led's when turn signal is activated. Now I'm planning to make another version which would automatically switch from DRL to low beam once it's getting darker. It could be easily done by LDR but the problem is how to make it so that it wont turn lights off when under street lights or other artificial lights? Is there light sensor which disregards artificial lights? It could eg. sense the blinking of AC current 50 or 60hz and disregard that. Only natural light (and DC light) would be registered. Ideas?
Your help is greatly appreciated.
