We found the best color sensor on the market, the TCS34725, which has RGB and Clear light sensing elements. An IR blocking filter, integrated on-chip and localized to the color sensing photodiodes, minimizes the IR spectral component of the incoming light and allows color measurements to be made accurately. The filter means you'll get much truer color than most sensors, since humans don't see IR. The sensor also has an incredible 3,800,000:1 dynamic range with adjustable integration time and gain so it is suited for use behind darkened glass.

Color issue with the TDS34725

Hello, I have a color issue with the TCS34725. I used the code given with it :

#include <Wire.h>

include "Adafruit_TCS34725.h"

/* Example code for the Adafruit TCS34725 breakout library */

/* Connect SCL to analog 5
Connect SDA to analog 4
Connect VDD to 3.3V DC
Connect GROUND to common ground */

/* Initialise with default values (int time = 2.4ms, gain = 1x) */
// Adafruit_TCS34725 tcs = Adafruit_TCS34725();

/* Initialise with specific int time and gain values */
Adafruit_TCS34725 tcs = Adafruit_TCS34725(TCS34725_INTEGRATIONTIME_700MS, TCS34725_GAIN_1X);

void setup(void) {
Serial.begin(9600);

if (tcs.begin()) {
Serial.println("Found sensor");
} else {
Serial.println("No TCS34725 found ... check your connections");
while (1);
}

// Now we're ready to get readings!
}

void loop(void) {
uint16_t r, g, b, c, colorTemp, lux;
int Teinte;
String Couleur;
tcs.getRawData(&r, &g, &b, &c);
colorTemp = tcs.calculateColorTemperature(r, g, b);
lux = tcs.calculateLux(r, g, b);

Teinte=getTeinte(r, g, b);
Serial.print("H : "); Serial.print(Teinte, DEC); Serial.print(" ");
Serial.println("");
AfficheCouleur(Teinte);

/Serial.print("Color Temp: "); Serial.print(colorTemp, DEC); Serial.print(" K - ");
Serial.print("Lux: "); Serial.print(lux, DEC); Serial.print(" - ");
Serial.print("R: "); Serial.print(r, DEC); Serial.print(" ");
Serial.print("G: "); Serial.print(g, DEC); Serial.print(" ");

Serial.print("Teinte: "); Serial.print(Teinte, DEC); Serial.print(" ");
Serial.println(" ");/
delay(5000);
}

float getTeinte(uint16_t pr, uint16_t pg, uint16_t pb)
{
int H;
float r= (float)pr/255;
float g= (float)pg/255;
float b= (float)pb/255;
float Cmax = Max(r, g, b);

Serial.print("r: "); Serial.print(r,2); Serial.print(" ");
Serial.print("g: "); Serial.print(g,2); Serial.print(" ");
Serial.print("b: "); Serial.print(b,2); Serial.print(" ");
Serial.print("Cmax: "); Serial.print(Cmax,2); Serial.print(" ");
float Cmin = Min(r, g, b);
Serial.print("Cmin: "); Serial.print(Cmin,2); Serial.print(" ");
float Delta = Cmax - Cmin;
Serial.print("Delta: "); Serial.print(Delta,2); Serial.print(" ");
Serial.println("");

H= getH(r, g, b, Cmax, Delta);
return H;
}

float Min(float pr, float pg, float pb)
{
if(pr<pg && pr<pb)
return pr ;
else if(pg<pb && pg<pr)
return pg ;
else
return pb ;
}

float Max(float pr, float pg, float pb)
{
if(pr>pg && pr>pb)
return pr ;
else if(pg>pb && pg>pr)
return pg ;
else
return pb ;
}

int getH(float pr, float pg, float pb, float pCmax, float pDelta)
{
int Temp;
if(pDelta==0)
return 0;
else if(pCmax==pr)
{
Temp= 60_((pg-pb)/pDelta);
Temp= Temp%6;
}
else if(pCmax==pg)
Temp= 60_(((pb-pr)/pDelta)+2);
else
Temp= 60*(((pr-pg)/pDelta)+4);
return Temp;
}

void AfficheCouleur(int pH)
{
String Couleur;
if( (pH<=15 && pH>=0))
Serial.print("Couleur: Rouge ");
else if(pH<=45 && pH>15)
Serial.print("Couleur: Orange ");
else if(pH<=75 && pH>45)
Serial.print("Couleur: Jaune ");
else if(pH<=135 && pH>75)
Serial.print("Couleur: Vert ");
if(pH<=255 && pH>135)
Serial.print("Couleur: Bleu ");
else if(pH<=345 && pH>255|| pH>345)
Serial.print("Couleur: Violet ");
Serial.println("");
Serial.println("");
}

But the pH is always below what it need to be, if I put yellow on the captor, the pH will be between 1 and 5. If I put black, the pH is green. I have this problem on 2 drivers.
