The TCS34725 is a high-precision digital RGB color sensor perfect for IoT, smart devices, and embedded applications that need reliable color detection. It integrates red, green, and blue filters with a 16-bit ADC for each channel, providing accurate color measurement in reflected or transmitted light.
With built-in IR suppression, I²C communication, and configurable gain and sampling time, this sensor is developer-friendly and ideal for projects where color accuracy and low power consumption matter.

Industrial automation for color sorting or quality control
🧩 Arduino Integration Example
Easily connect via I²C:
include
include "Adafruit_TCS34725.h"
Adafruit_TCS34725 tcs = Adafruit_TCS34725(TCS34725_INTEGRATIONTIME_700MS, TCS34725_GAIN_1X);
void setup() {
Serial.begin(9600);
if (tcs.begin()) {
Serial.println("TCS34725 sensor detected!");
} else {
Serial.println("No TCS34725 found ... check connections.");
}
}
void loop() {
uint16_t r, g, b, c;
tcs.getRawData(&r, &g, &b, &c);
Serial.print("R: "); Serial.print(r);
Serial.print(" G: "); Serial.print(g);
Serial.print(" B: "); Serial.println(b);
delay(1000);
}
