Color sensor, light transducer - frequency TCS3200D - module Iduino ME069

Description

The module with TCS3200D sensor allows the measurement of the color (RGB - Red, Green, Blue), the output of which is frequency dependent on the intensity of light of the selected color. It is supported by any commissioning set with a microcontroller equipped with a counter, for example,STM32DiscoveryorArduino.

 

Specification

Service and output

The module is powered with the voltage in the range of 2.7 V to 5.5 V, thanks to it, it is reliable in the systems of 3.3 V and 5 V. The sensor can be connected to any commissioning set with a microcontroller that has a timer with the frequency input, for example,STM32DiscoveryorArduino.

The output is a signal with a frequency that depends on the light intensity of the color selected by the pins S2 and S3.

Detailed description of the pins is available in the arrays in the further part of the description. Pins are the popular goldpin connectors, allowing for the connection of the sensor with the main module using theconnecting cables.

Setting

Using the configuration inputsS0andS1, selected is prescaler (divider) of the output frequency signal thanks to which we can adjust the frequency range for the used microcontroller. InputsS2andS3are used to selectthe type of measuring photodiode: red, green, blue or clear options, that is without filtering (all RGB components will be measured simultaneously).
