I'm building a circuit to control brightness of few leds. The brightness should be proportional to ambient light, which can vary from dark night to bright day.
Could someone point me a sensor (outputs voltage), which can feed me a voltage linearly proportional to ambient light.
I have found many chips like this -> http://www.taosinc.com/productdetail.aspx?product=62 , but if I have understood right, that chip can't make a difference in irradiance when the day is very bright. Am I right?
Thanks.
