I want to install some LED stripes on my motorcycle, i.e. as brake light and indicators. I use WS2812 LED stripes which can be very bright - especially with many LEDs on at the same time.
I want to measure the ambient light so that in the bright sun I can light the LEDs with, let's say, 100%. But in the night maybe just with 30% intensity. I want to detect the ambient light to change the intensity.
I don't need high resolution and I don't need high speed. If the ambient light is measured i.e. once per second with 4 bit resolution that would be already good enough.
Which ambient light sensor (or photo diode or whatever) makes sense for this little project and how to connect it? Does it make sense to use more than one light sensor for a better average ambient light value (just in case one sensor is in the shadow, another in the sun)?
I found these sensors form a Chinese supplier:
But an I2C interface seems to be overkill for my simple project.
