TCS3200 Color Sensor Module

TCS3200 Color Sensor Module – Light & Color Sensors

The TCS3200 is a compact, programmable color‑to‑frequency sensor that detects red, green, blue, and clear light and outputs a square‑wave frequency proportional to the intensity of each hue. Plug‑and‑play ready for Arduino, Raspberry Pi, and micro:bit, the module lets students turn raw light data into meaningful colour values with just a few lines of code. By building projects such as a color‑sorting robot, a smart LED lamp, or a fruit‑ripeness detector, learners explore optics, signal processing, and the mathematics of hue, saturation, and brightness.

What students will learn:

• Fundamentals of photodiodes and light‑frequency conversion
• How to calibrate sensors and handle ambient‑light interference
• Programming concepts for reading, scaling, and interpreting frequency data
• Real‑world applications of color detection in robotics, environmental monitoring, and art

Key features:

• Four photodiodes (R, G, B, and clear) with built‑in IR filter
• Adjustable scaling (2 %–100 %) for precise control of output frequency
• Simple 5‑pin interface (VCC, GND, OUT, S0‑S1) compatible with most development boards
• On‑board white LED for consistent illumination in low‑light conditions
• Robust PCB, solder‑pads, and clear documentation for quick prototyping

Why it’s perfect for STEAM education: The TCS3200 bridges science (optics, wavelengths), technology (sensor integration), engineering (circuit design, calibration), art (color theory, interactive installations), and mathematics (frequency‑to‑color conversion). Its hands‑on, visual feedback engages students of all ages, fostering curiosity and problem‑solving skills while providing a versatile platform for interdisciplinary projects that span classrooms, makerspaces, and robotics clubs.
