XH2.54 3PIN Ambient Ligh Sensitive LDR Photo Sensor Module For Arduino Tutorial Analog Output
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.
Connector: XH2.54 × 3
Instructions for use: Connect the power supply and read the analog quantity of the signal pin to know the light intensity.
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:
lightLevel = analogRead(A0);
}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
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.
