TCS3200 Description

The TCS3200 programmable colour light-to-frequency converters combine configurable silicon photodiodes and a current-to-frequency converter on a single monolithic CMOS integrated circuit. The output is a square wave (50% duty cycle) with frequency directly proportional to light intensity (irradiance).

In the TCS3200, the light-to-frequency converter reads an 8 x 8 array of photodiodes. Sixteen photodiodes have blue filters, 16 photodiodes have green filters, 16 photodiodes have red filters, and 16 photodiodes are clear with no filters.

The four types (colours) of photodiodes are interdigitated to minimize the effect of non-uniformity of incident irradiance. All photodiodes of the same colour are connected in parallel. Pins S2 and S3 are used to select which group of photodiodes (red, green, blue, clear) are active. Photodiodes are 110 μm x 110 μm in size and are in 134-μm centres.

How to use TCS3200 Color Sensor Module?

This Arduino compatible TCS3200 colour sensor module consists of a TAOS TCS3200 RGB sensor chip and 4 white LEDs. The main part of the module is the TCS3200 chip which is a Color Light-to-Frequency Converter.

With the help of a microprocessor, the TCS3200 colour sensor module can detect colours. The output frequency from the 6th pin is really measured by the microcontroller.

When each filter is activated, we must measure the frequency from the 6th pin to determine the colour of an object.

Set both S2 and S3 to LOW and take a frequency reading. Now we get the object's RED component's intensity.

To get the intensity of the BLUE component in the object, set S2 to LOW and S3 to HIGH.

Set both S2 and S3 to HIGH to determine the object's GREEN component's intensity.

To determine the true colour of the object, compare the frequencies of the three components.

TIP: In Arduino, we can use the ‘pulseIn’ command to get the frequency variations.

e.g.: 
digitalWrite(S2, LOW);digitalWrite(S3, LOW);   //Activating photodiode with red filter
red = pulseIn(outpin, LOW);

The value corresponding to the red color component of the object color is obtained here.

Similarly, we must change the S2 and S3 states of each photodiode and read the appropriate values of the green and blue color components of the object color.

We get an estimated value of red=16, green=53, and blue=45 for a Red item. Ambient light and experiment setting may influence this. It is preferable to shield the item and sensor from ambient light for the best results.

Frequently Asked Questions

How does TCS3200 Color Sensor work?

The TCS3200 senses color light with the help of an 8 x 8 array of photodiodes. Then using a Current-to-Frequency Converter the readings from the photodiodes are converted into a square wave with a frequency directly proportional to the light intensity. Finally, using the Arduino Board we can read the square wave output and get the results for the color.

What is the benifit of TCS3200?

Enables high-resolution conversion of light intensity to frequency
Disables the output into a Hi-Impedance state when the OE input pin is Low
Enables output range to be optimized for a variety of low-cost measurement techniques
Reduces board space requirements while simplifying designs

How to program color sensor tcs3200?

First set the input pins as input and output pins as output. No need to use analogue pins.

Set S0 and S1 to high or low to set desired frequency scaling.

In a loop, activate each filter by setting S2 and S3 to HIGH or LOW and measure frequency ‘fo’ from the 6th pin to get corresponding colour intensity. Compare frequencies of each colour to determine the colour of the object.
