Data String Problem

Hi, I am working with an Arduino sensor that gives out a series of three strings data that I want to visualize in the serial monitor. The problem I have is that as first printout at the SM the system returns a number (44 actually) that has nothing to do with the sensor readouts but is messes up the serial communication with another app I am writing in Python. How can I prevent that number 44 for being returned/printed, either from the Arduino or Python side ?. Thanks, Alejandro.

Are you missing some of your setup code?

Here it goes, thanks

#include <Wire.h>
#include "Adafruit_TCS34725.h"
Adafruit_TCS34725 tcs = Adafruit_TCS34725(TCS34725_INTEGRATIONTIME_101MS, TCS34725_GAIN_4X);
const int activationPin=13;
const int sensorLEDpin= 3;
const int lightpin=11;

void setup(void) {
      pinMode(activationPin, OUTPUT);
      pinMode(sensorLEDpin, OUTPUT);
      pinMode(lightpin, OUTPUT);
      Serial.begin(9600);

void loop(void)
{
    digitalWrite(activationPin, HIGH);
    analogWrite(sensorLEDpin, 1);
    analogWrite(lightpin, 15);
    uint16_t r, g, b, c, colorTemp, lux;
    tcs.getRawData(&r, &g, &b, &c);
    Serial.print(r,DEC); Serial.print(","); Serial.print(g,DEC); Serial.print(","); Serial.print(b,DEC);
}

So from reading Adafruit library examples

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

have you tried the Adafruit samples provided with the library and do they work ok

hi, thank you, finally I got it working, the issue was at the sensor library.

No Data

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