TCS3200 Color Recognition Sensor Module

The TCS3200 color recognition sensor module reads surface colour by measuring the intensity of red, green, and blue light reflected from an object. It is an RGB (red-green-blue) colour sensor that converts light intensity into a frequency output (a signal whose rate changes with brightness), which your microcontroller counts to determine colour. The tcs3200 color sensor works at 2.7V to 5.5V so it suits both 3.3V and 5V systems without any level shifting.

One non-obvious technical detail is that the output is a square wave frequency and not a voltage level, so you read it using pulseIn() or interrupt counting in your code rather than analogRead(). This surprises most beginners the first time. The honest limitation is that ambient lighting changes the reading noticeably, so always shield the sensor close to the target surface for reliable colour detection sensor results.

Robotics developers and learners use the color sensor arduino setup for sorting machines and colour-based robot navigation. Connect the four digital output pins and S0–S3 filter selection pins to Arduino Uno or ESP32. Set the filter pins, then count the output frequency to identify colours. StemVolt provides this sensor with trusted quality, ensuring reliable performance and easy usability.
