Hello guys
We are a couple of guys doing our final project in electronics at our school. We want to make a device for a car, that can sense light from other cars and turn down the headlights. We plan to do this by using an LDR, photodiode or photo transistor - the question is just if it'll be able to sense the light of a car more than 100 meters away.
We're also wondering how we should calculate this? I assume it has something to do with lumen and lux, but how exactly would we do?
Another problem is the rear lights. Is it possible to get a photodiode that can read only wavelengths of 600nm and above (for red light) and another one to get the light from the headlights?
Thanks in advance
