Waveshare Color Sensor 9520 Board Module

Overview 1. Sensor Chip: TCS3200 (RGB color detector) 2. Detects static color, the output is a square wave with frequency directly proportional to incident light intensity 3. Supports fill-light by onboard LEDs Specifications 1. Power: 2.7V ~ 5.5V 2. Ideal detection distance: 10mm 3. Dimension: 36.0mm * 20.6mm 4. Mounting holes size: 2.0mm Applications 1. Sorting by color 2. Ambient light sensing and calibration 3. Test strip reading 4. Color matching How to Use In the case of working with a MCU: 1. VCC: 2.7V ~ 5.5V 2. GND: Power supply ground 3. LED: MCU.IO (controlling the 4 white LEDs) 4. OUT: MCU.IO (RGB color output frequency) 5. S0/S1: MCU.IO (Output frequency scaling selection inputs) 6. S2/S3: MCU.IO (Photodiode type selection inputs) 7. S0/S1 selects the output frequency scaling factor, S2/S3 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. Note: 1. Avoids environment light noise 2. White balance is required when the first time using the module, reseting the module, or changing the light source
