Color Sensor TCS34725 Pinout Diagram and Connection with Arduino

Hi, in this article, we are going to see the Color Sensor TCS34725 Pinout Diagram and Connection Diagram for interfacing it with Arduino. The TCS34725 is a popular RGB color sensor that can detect red, green, and blue light intensity and it has an IR filter for accurate color measurements. This Color Sensor Module uses an I2C Interface that simplifies communication with microcontrollers like Arduino or Raspberry Pi. The Color Sensor TCS34725 has an On-chip ADC(Analog-to-Digital Converter) that converts analog signals from photodiodes into 16-bit digital values. This color sensor can work well in low-light conditions.

Interfacing Color Sensor TCS34725 with Arduino

Here, you can see the connection diagram of Color Sensor TCS34725 and Arduino.

Connection Description

• The Vin and GND terminals of the Color sensor are connected to the 5V and GND terminals of the Arduino.
• The SDA terminal of the color sensor is connected to the Analog input A4 terminal of the Arduino.
• The SCL terminal of the color sensor is connected to the Analog input A5 terminal of the Arduino.
• The LED Control terminal of the color sensor is connected to the Digital Output Pin no. 5 of the Arduino.

Working Principle

The TCS34725 color sensor detects color and ambient light using its photodiodes and an integrated IR filter. It measures the intensity of Red (R), Green (G), Blue (B), and Clear (C) light and converts these into digital values for further processing.

The TCS34725 basically has four photodiodes that detect red, green, blue, and clear (non-filtered) light intensities. These photodiodes measure the light reflected from an object. The built-in IR blocks, filters, and eliminates interference from infrared light, which can distort the color readings.

The sensor converts the detected light intensities into 16-bit digital values using an on-chip analog-to-digital converter (ADC). 

When the color sensor is connected to the Arduino, the digital values for red, green, blue, and clear light are sent to the Arduino via the I2C communication.
