Ambient light and proximity sensors sense distances up to 10cm
With its APM-16D17-05-DF8-TR8 and APM-16D17-06-DF8-TR8 ambient light and proximity sensors, Everlight aims to save energy and reduce unwanted signals and noises when used in smartphones, tablet PCs, residential smart lighting and digital signage applications. [via]
Both series use a specially coated photo diode with an optical response similar to human eyes. They have a common I²C interface allowing them to be driven with a supply voltage of only 1.7V. They are optimized to sense the ambient brightness and adjust the backlight of a screen to the most clear and comfortable settings. For example, the screen gets brighter in shining daylight but darkens in a dark environment.
