How the GY-31 TCS230 Color Sensor Works

The TCS230 color sensor uses a matrix of photodiodes covered with different color filters. By selecting the filter type using control pins (S2 and S3), the sensor measures the intensity of red, green, blue, or clear light. The sensed light intensity is then converted into a proportional frequency output, which can be read by a microcontroller using timers or interrupt-based counting.

This digital frequency-based output makes the GY-31 sensor less susceptible to electrical noise compared to analog color sensors, ensuring stable operation even in electrically noisy environments.
