Can someone please post the datasheet for the colour sensor mentioned above. All i can find is for TCS3200
One thing I find helpful for minimal or missing datasheets is to look for Arduino/PIC or other code examples and discussions on the module. The basic datasheet has wiring - but no actual usage help, where as forum discussions and code examples will get you some actual results from it. This one looks promising.
Are you looking for the TCS230 or the TCS3200? If its the TCS3200 GY-31 (which is the upgraded module from the TCS230), you can try this.
Its not the most informative, but it does cover the basics for the GY-31.
