Aimed at applications such as automatic light and LCD backlight control,
Panasonic's versatile PNJ4K01F ambient light sensor is now stocked by

The device features a built-in photodiode and current amplifier circuit. It
allows for automatic control of display luminosity relative to ambient
brightness. With a spectral response similar to that of the human eye, it's
possible to design brightness control schemes that are tuned for optimal
human sensitivity. This, along with a small package size and low power
consumption, makes the PNJ4K01F ideal for applications in mobile
electronics, says the company.
