Product description:

  1. On board tcs3200 chip color sensor module
  2. Input Voltage: 3v - 5v 
  3. Chip pin all decanning , pin for standard 100mil ( 2.54mm ) , convenient used for matrix board 
  4. PCB : measurement 31.6 ( mm ) x24.4 ( mm )

Use:

With modern industry to high speed ,automation development ,production process of long by predominate analysized the color identification work will more and more is correspondingly color sensor by vicarious; such as : library use color to distinguish between literature classification , greatly improve rack management and statistical etc .

In the packaging industry , produce packing use different color and decoration express their different nature or usage .Present color sensor is usually in independent photoelectric diode covered adjusted red ,esent filter ,then to output signal subsides ,can send the color signal identification ,some congregated for both ,output analog signal ,need a a/d circuit acquisition , the signal further processing ,can to identify the ,increase the circuit complexity and the large identification error ,the impact of recognition effect . taos (texas advanced optoelectronic solutions ) company new arrival launch of the color sensor tcs230 can not only the realization of color recognition and detection , with the former color sensor compared , has many excellent new feature .

Features:

TCS230 chip features- TCS230 is taos company launched programmable multicolour light to frequency converter , it can be put configuration silicon photion with current frequency converter integrated in a single cmos circuit , single chip at the same time integrative red-green-blue ( rgb ) three kinds of filter is the first digital 's compatible interface rgb multicolour sensor , tcs230 the output digital , can drive standard 's ttl or cmos logic input , therefore can directly with microprocessor or others logic circuit phase , the output is digital quantity , and can achieve each channel multicolour 10 above the accuracy , consequently in no need a/d converter , make circuit easier .

Package- TCS230 adopt 8 pin 's soic surface mount package ,on a single chip integrated 64 a photo diode , these diode divided into four type ,its 16 a photo diode band have red filter .16 a photo diode band have green filter . 16 a photo diode band have blue filter , rest 16 a without any filter , can through the light information , these photodiode chip inside is cross array 's , can minimizes radiation of impinging light inhomogeneity , thereby increase color accuracy identification . other hand , the same color of 16 a photo diode is the parallel , uniform distribution in diode array , can eliminate the color of the position error . work when , by two programmable pin dynamic select the filter , the sensor typical output frequency range from 2hz - 500khz user can also two programmable pin to choose 100 , 20 or 2 the output proportionality factor , or power supply shuldown model . output proportionality factor sensor the output can adapt to different measuring range , the adaptiveness . such as , when using low speed frequency counter when , can select small value calibration , make tcs230 the output and frequency counter match

Pin Configurations-  When incidence light to cast tcs230 when ,by photodiode control pin s2 ,s3 different combination , can choose different filter . After the current to frequency converter after the different output frequency squarewave ( dielectrics is 50 ) ,different color light for different frequency squarewave .Also can outputted through control calibration pins0 , s1 choose different output proportionality factor , output frequency range adjustment , to adapt to different demand . 

Pin Functions- Brief introduction tcs230 chip various pin functions and some combination options are shown below: 

  • S0 ,S1 used for select output power supply or proportionality factor shuldown model
  • S2 ,S3 used in selection filter type
  • OE is frequency output enable pins ,can control the output state ,when you have more chips pin microprocessor sharing the output pin when ,also can be used as chip select 
  • OUT is frequency output pin
  • GND chips ground pin
  • Vcc for chip provide work voltage

Color identification principle tcs230   

By the introduction of knowable , this programmable multicolour light to frequency converter suitable for colorieter measurement field of application , such as multicolour printing , medical diagnosis , computer multicolour monitor calibration and paint textiles , , cosmetics printing materials process control and colors with . the following tcs230 in liquid color recognition application of , it concrete use . know first some light and color knowledge . 

1. Trichroic sensor principle 

Usually what you see object color is actually the object surface absorbed the radiation to it above white light ( fluorescent ) part of non ferrous ingredient ,whereas reflected another part light in the eyes of reaction .

White is from all kinds of frequency visible light mixed in ,also is said challengoogle earthd contains a variety of color color (red r, yellow y ,green g ,green v ,blue b , purple p ) . according to the heirships helmholtz (helinholtz ) 's trichromatic theory knowable, various color of different the proportion of trichroic ( red , esent ) mixed .

2. tcs230 recognition color the principle 

Trichroic by induction principle knowable ,if you know the entire color 's trichroic value ,it can know test objects of color .For tcs230 to say ,when the selected a color filter when ,it is allowed only particular primary colors through ,prevent others primary colors through such as : when to choose red filter when, only in the impinging light red can through, blue and green block all ,access light red light strong, at the same time choice others filter, can get light blue and green light light intensity, through the three value, can be projection tcs230 sensor on the light of color. 

3. White balancing and color identification principle 

White balancing; theoretically, white is by red, equivalent of green and blue mixed issweet, but actually, white three primary colors are not completely equal and for tcs230 light sensor to say, it on the three basic color the sensitivity is not the same, led to tcs230's rgb output is not equal, therefore in testing before the white balancing adjustment, makes tcs230 for measuring " white " three primary colors are equal .Carry on white balancing is for succedent adjust the color recognition prepare in this device, white balancing adjustment concrete steps and as follows null test tube placed in sensor above, test tube above to place a white light, optical to pass test tube irradiate tcs230, according to the front of the introduction to method, sequentially, strobe red and green and blue filter, separately, measured red green and blue 's value, then 's calculations 3 adjustment arguments. 

Color Recognition Methods- When tcs230 color recognition when , just use this 3 a sample of color 's determination r , g and b adjust, there are two method to calculate : setting 1 a seriatim , strobe three color filter , and then tcs230 the output pulse in turn for counting . when to 255ceased when the counting , calculated separately each channel used in time , these time corresponds to actual tests tcs230every kind of filter used in time base , in this time measuring pulse number is corresponds to r , g and b value . 2 , set timer for a fitted time ( such as 10ms ) , then strobe three kinds of color filter , calculation of this time tcs230 the output pulse number , compute a proportionality factor , through this can put proportionality factor these pulse number to length-1 255 . in the actual tests , outdoor same time for counting , put the measured pulse , times 's proportionality factor eular , then you can get the corresponding r , g and b value . 

Problems in Color identification:

  1. Color for identification to avoid light outside interference , the effect of color will otherwise result of recognition , best sensor , light source such as placed in a tight , lockages none reflection tested .
  2. Light source no special requirement of , but the light source light to try concentrated , otherwise sensor between each other distractions.
  3. When the 1 times use tcs230 when or tcs230 identification module restart, change the lamps so on, need a white balancing readjustment .
