Light sensors are most commonly present in industrial lighting, electronic
devices, and automotive systems, where they provide settings to be adjusted
automatically in response to changing ambient light conditions. By activating,
switching off, or modifying features, ambient light sensors can conserve
electric batteries and supply extra safety while eliminating the requirement for
manual adjustments. Token offers a wide variety of ambient light sensors in
leaded and surface mount packages, with photodiode or phototransistor outputs.
In portable electronic products, lowering the power consumption to supply the
consumer with elevated battery existence is among today’s critical design
factors. The liquid crystal display (LCD) which is connected backlighting are
the more power hungry loads in portable products. Consequently, using an ambient light sensor (ALS) to
optimize the whole process of the backlight LEDs under a number of ecological lighting situations is growing
while, simultaneously, the most well-liked technology choices open to designers for sensing have shifted
towards more integrated solutions.
Token chip ambient light sensors can be used in a variety of LCD-equipped portable products including PDAs,
notebook PCs, digital cameras, video players, GPS-based navigation systems, and more. Any portable product
by having an LCD is really a candidate for ALS technology to lessen power consumption.
Token taking the advantage of temperature compensation internal process on the chip, (PTA1AC3528-850)
features one times higher temperature resistance than other similar products while working on high temperature
environment. By selecting the accuracy of chips, under strict management of production process, chip visible
light sensors finished batch consistency uniform. The consistency is 3 to 5 times higher on comparison of
similar photosensitive devices. Please contact our sales or link to Token official website “Ambient-light-sensors”
for more information.
The (PTA1AC3528-850) is a sensor with near the human
eye that measures the intensity of visible light.
