I realized how nice it is to have a digital camera that has a nice white balance function early on in this project, since I had calibrate my own white balance in this circuit. Because the LED's were of different intensities and the sensor prefers red and infrared light, I tuned the intensity of each LED with different resistor values so that the sensor output the same voltage for each color when it was scanning a white sheet of paper (i.e., custom white balance). I was using a common anode Tricolor LED from [[http://www.superbrightleds.com/TriColor%20LED.htm | Super Bright LEDs]]. I used a 470-ohm resistor for the red LED, a 47-ohm resistor for green, and a 380-ohm on blue. In doing this, the sensor output approximately 925mV for each individual color on a sheet of white paper:

Using the TSL13S is straightforward - connect power and ground to the appropriate pins to turn it on. To interface with a microcontroller, simply connect the output pin to an ADC pin. The TSL13S maybe used in a comparator circuit as well, so connect the output pin to one of the inputs of the op amp in that circuit.

Supply voltage (V'_DD_') must between 2.7V and 5V, with an absolute maximum supply of 6V. The sensor requires 1.1 - 1.7mA of current to run. Both voltage and amperage requirements are well within the range of a typical voltage regulator or from sourcing a microcontroller. Output voltage will range from 0.0V to a maximum of 4.9V. Typical 'dark' voltage (when the sensor is not receiving light) will be 0.0V, but may output 0.08V. Amperage output will range from 10mA.

The TSL13S will output 246 mV per μW/cm2. As a [[http://en.wikipedia.org/wiki/Solar_power#Energy_from_the_Sun | reference]], the Sun's peak irradiance at the Earth's equator is 1,020 W/m. According to this [[http://www.medscape.com/viewarticle/551363_6 | site]] a fluorescent bulb 10 cm above a surface will "achieve irradiance of 50 W/cm2."

I used this sensor to make a very simple, low resolution scanner. I attached a cardboard tube to a wooden board and placed a TSL13S and a tricolor LED (common anode) inside that tube against the wood. I programmed the arduino to cycle through the three colors of the LED, taking a reading of the sensor value for each color. The cycle went something like this:
-> #Turn on red LED
-> #Pause
-> #Take a sensor reading of how much red light is reflected back. (The more 'red' something is, the more light will be reflected)
-> #Turn off red LED
-> #Pause
-> Repeat with green, then blue LEDs

The sensor is part of a larger light-to-voltage sensor family made by [[http://www.taosinc.com |Texas Advanced Optoelectronic Solutions]] (TAOS). It responds to light with wavelengths in the range of 320nm to 1050nm. This range translates to just above the 'Near-UV' range (which is 200 - 400nm) through about half of the 'Near-Infrared range' (750 - 1400nm) and all of the visible light in between. The bell curve of the photodiode's spectral responsivity peaks near 760-780nm (a range just above the limit that most humans would perceive as the color 'red').

Supply voltage (V'_DD_') must between 2.7V and 5V, with an absolute maximum supply of 6V. Output voltage will range from 0.0V to a maximum of 4.9V. Typical 'dark' voltage (when the sensor is not receiving light) will be 0.0V, but may output 0.08V.
Changed lines 33-34 from:
There are three pins on this sensor - Ground, V'_DD_', and OUT. Supply voltage (V'_DD_') must between 2.7V and 5V, with an absolute maximum supply of 6V. The Output pin should be connected to ground ('pulled down') through a 10K-Ohm resistor (but I didn't find this necessary). Output voltage will range from 0.0V to a maximum of 4.9V. Typical 'dark' voltage (when the sensor is in the dark) will be 0.0V, but may output 0.08V.

Initial report by [[~chris | Chris Kucinski]] - 4 April 2007

Put a paragraph or two here introducing the the sensor. You might want to add an introductory image as well.


!!!Sources

Outline here where you got your sensor, how much it cost and what your experience of getting it was like.


!!!Applications

Describe some typical applications of this sensor. You can often get this from the datasheet, but a few examples from companies or individuals who've used it would be useful as well.

!!!Electrical Characteristics
Put a link to the datasheet at the top. Also link any retail sources, for example if you're using a breakout board, or any other parts that making the sensor easier.

Give the voltage and amperage ranges, and any other relevant electrical data.

Describe the electrical changes when the sensor senses whatever physical changes it senses.

!!! Pin Descriptions
Give a list of the pins, and a pin diagram as appropriate. Detail the function of each pin in a short paragraph following the list.


!!!Microcontroller Connections
Explain how to connect the sensor to a microcontroller or computer. Include a schematic and any other necessary diagrams. Make sure to include a list of every part in the schematic.

!!!Code Sample
Give a code sample for the microcontroller you developed the example on. Link it to the Code group of the wiki, formatting the link like this:

[=[[Code.myCodeSample | Code Sample]]=]

!!!Typical Behavior
Describe the behavior of the sensor when you use it to sense something. Note any peculiarities that you had to work around, or things that might affect someone else's use. Graphs and images are useful here.

!!!Application Notes
Describe your own application of the sensor. Link to any external documentation of your project, and discuss how you got the sensor to do what you needed it to.
