TCS3200 color sensor module

In summary, a TCS3200 is a programmable color light-to-frequency converter. It has a configurable silicon photodiode and a current-to-frequency converter on a single CMOS.

The following are some key points;

1. High-Resolution Conversion of Light
2. Intensity to Frequency
3. Programmable Color and Full-Scale Output
4. Frequency
5. Communicates Directly With a Microcontroller
6. Single-Supply Operation (2.7 V to 5.5 V)
7. Power Down Feature

It generates the square wave output with a 50% duty cycle with frequency directly proportional to light intensity. You can scale the output frequency to three preset values by two control input pins.

You can easily integrate it into any Arduino board or microcontroller board using Digital input and output pins. Output Enable (OE) pin places the output in the high-impedance state for multiple-unit sharing of a microcontroller input line.

The TCS3200 has an 8 x 8 photodiodes array in which every 16 photodiodes group has blue, green, red, and clear filters. That allows it to convert light to frequency.
