Color sensor Arduino expansion board Joy-IT TCS3200 — sen-color module for color detection

The Joy-IT TCS3200 Arduino expansion board sen-color is a compact interface module that integrates the TCS3200 color sensor with Arduino-compatible development boards. It is designed to detect and measure color by converting light intensity from red, green and blue filters into frequency output. The board provides standardized connections for power and signal lines so the TCS3200 sensor can be used in prototypes and educational projects such as color sorting, ambient light color measurement and simple optical sensing tasks.

Advantages

This expansion board offers an easy-to-use hardware interface that simplifies connecting the TCS3200 color sensor to Arduino systems. The module exposes the sensor’s control and output pins in a compact layout, reducing wiring complexity and accelerating prototyping. It is suitable for learning and development environments where quick integration of color detection functionality is required. The board preserves the TCS3200’s ability to select different photodiode filters and output frequency ranges for adaptable measurements.

Suitable for

• Color sorting and classification projects with Arduino
• Measuring light color and basic colorimetry experiments
• Educational electronics and microcontroller training
• Prototyping sensors for robotics or automation tasks

Key specifications

• Sensor type: TCS3200 color sensor module (RGB photodiode array with frequency output)
• Interface: Arduino-compatible signal and control pins exposed for digital input/output
• Output: Frequency signal proportional to detected color intensity
• Control: Pins for filter selection and output scaling to adjust sensitivity
• Form factor: Compact expansion board suitable for breadboard or shield-style connections

How to use

Connect the expansion board to an Arduino-compatible board using the exposed power (VCC, GND) and signal pins. Use the control pins to select the desired photodiode filter (red, green, blue, or clear) and to set the output scaling where available. Read the sensor’s frequency output on a digital input pin and convert frequency to intensity in software, using example libraries or routines for the TCS3200. Calibrate the sensor for ambient lighting and target colors by measuring reference samples and adjusting thresholds in your sketch.

Usage recommendations

For reliable measurements, perform calibration under the same lighting conditions as intended operation, avoid strong direct reflections, and use consistent distance and orientation between the sensor and the target. When integrating with Arduino projects, use existing TCS3200 libraries and sample code to speed development and ensure correct frequency-to-color conversion.
