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
