Color Sensor TCS3472

This specific color sensor is configured via properties on the MBLPhotometerTCS3472 class. This section shows how to use its advanced features.

Configuration

The color sensor has 2 configurable parameters that affect the data range, resultion, and sensitivity.

Parameter	Description
Gain	Analog signal scale
Integration Time	Amount of time spent to aggregate adc values

There is also a white illuminator LED next to the sensor that can be used to provide additional light if the surrounding area is too dark.

// set gain to 4x, integration time to 4.8ms,
// keep illuminator led off
photometerTCS3472.gain = .gain4X
photometerTCS3472.integrationTime = 4.8

ADC Values

The red, green, blue, and clear ADC values measured by the TCS3472 device are represented by the MBLRGBData class.

    print("color adc = \(result)")
}
