Fangrui Product Details 1. Waveshare Color Sensor 9520 Board Module 2. Overview 3. Sensor Chip: Tcs3200 (rgb Color Detector) 4. Detects Static Color, The Output Is A Square Wave With Frequency Directly Proportional To Incident Light Intensity 5. Supports Fill-light By Onboard Leds 6. Specifications 7. Power: 2.7v ~ 5.5v 8. Ideal Detection Distance: 10mm 9. Dimension: 36.0mm * 20.6mm 10. Mounting Holes Size: 2.0mm 11. Applications 12. Sorting By Color 13. Ambient Light Sensing And Calibration 14. Test Strip Reading 15. Color Matching 16. How To Use 17. In The Case Of Working With A Mcu: 18. Vcc: 2.7v ~ 5.5v 19. Gnd: Power Supply Ground 20. Led: Mcu.io (controlling The 4 White Leds) 21. Out: Mcu.io (rgb Color Output Frequency) 22. S0s1: Mcu.io (output Frequency Scaling Selection Inputs) 23. S2s3: Mcu.io (photodiode Type Selection Inputs) 24. S0s1 Selects The Output Frequency Scaling Factor, S2s3 Selects The Color Filter Of Red, Green, Blue, Then Out Outputs A Square Wave With Frequency Proportional To The Selected Color Intensity. The Detected Color Can Be Determined By The Ratio Of The Intensity Of Red, Green And Blue. 25. Note: 26. Avoids Environment Light Noise 27. White Balance Is Required When The First Time Using The Module, Reseting The Module, Or Changing The Light Source
