XH2.54 3PIN Ambient Ligh Sensitive LDR Photo Sensor Module For Arduino Tutorial Analog Output
Description
The photosensitive sensor is sensitive to ambient light, generally
used to detect the brightness and light intensity of the
surrounding environment, and can sense the light source in a fixed
direction. It is connected with the controller and can read the
ambient light intensity, and can be made into a photoelectric
switch.
The HY-016(A) contact image sensor (CIS) module integrates a red LED light source, lens and image sensor in a compact housing. The module is designed for document scanning, mark reading, gaming and office automation equipment applications and is suitable for scanning documents up to 216 mm wide. An analog video output achieves a scanning rate of 346 sec/line. The HY-016(A) module employs proprietary CMOS image sensing technology from UCHI to achieve high−speed performance and high sensitivity.

Light Sensor Module Quickstart Guide (ref details from freetronics.com.au)
The Light Sensor Module provides a very simple analog output, so
all you need to connect it to your Arduino or compatible board such
as the Eleven is GND, 5V, and one analog input. On a 3.3V
microcontroller such as Freetronics EtherDue or Arduino Due, VCC
should be connected to 3.3V instead of 5V.
The module actually accepts any power source (VCC) between 3.0 and
5.5Vdc. Output voltage will vary between 0V and slightly less than
VCC.
You can use whichever analog input suits you best, but for this
example we'll use A0:
That's it! Couldn't be much easier.
The code is very simple as well. Just perform an "analogRead()"
call on the appropriate input to get a value between 0 and 1023
that represents the light level being detected. Copy and paste the
following code into a new sketch in the Arduino IDE, compile it,
upload it to your Arduino, and then open the serial monitor with
the baud rate set to 38,400bps:
int lightLevel;
void setup()
{
Serial.begin(38400);
}
void loop()
{
lightLevel = analogRead(A0);
Serial.println(lightLevel, DEC);
delay(200);
}The light level will be reported five times per second via the
serial console.

When you think of displays, what do you think of ?
Traditionally interpreted as a part of televisions and computers,
display technology is now everywherefrom
thermostats, handheld terminals, automotive infotainment systems,
automotive clusters, to electronic point of sale machines (EPOS)
and more. People like the display to be lit comfortably so it is
easy to see and not strain the eyes. In many of these applications,
ambient light sensors (ALS) are used to set the display rightness
based on the surrounding light conditions. Depending on the
environment a
product is designed to be used in, the problems present in
designing an ambient light sensor into these
products are trying to match human eye response,reaching the
correct IR rejection due to conditions
under dark glass, and maintaining long battery life.UCHI provides
not only the OPT3001 to
solve these problems, but also the OPT3001-Q1 that is an automotive
qualified device to be used in
infotainment systems.
A problem with display backlights in portable electronics is the
need to provide a clear picture in all
ambient light conditions while simultaneously optimizing the power
consumption to preserve battery
life. The same problem occurs with display backlights in stationary
applications, such as thermostats, but the environmental conditions
are varied. Stationary applications must provide a clear picture in
a variety of
light conditions, like florescent light, incandescent light, or no
light at all. Ambient light sensors from TI are
being designed into products such as these to provide information
to the display about the ambient light level surrounding the
display. This light level can then be used to automatically adjust
the display brightness via the backlight, providing just the right
brightness level for clear viewing, preserving power and avoiding
end user frustration that the display is too bright or too dim.
