TCS230 Color Detector Module

Description:
TCS230 Color Detector Module is a tool to detect the color of the light emitting from objects, anti-light interference, which can detect the color of non-illuminating objects. This color sensor is a programmable color light-to-frequency converter, which combines configurable silicon photodiodes and a current-to-frequency converter on a single monolithic CMOS IC. The base of its working is an 8-lead SOIC surface mount package with 64 photodiodes integrated on a single chip. These diodes are divided into four types,  16 photodiodes with red filters, 16 photodiodes with green filters, 16 photodiodes with blue filters and the remaining 16 without any filters, so all optical information can be transmitted by these photodiodes. These photodiodes are cross-arranged within the chip to minimize the unevenness of incident light radiation which result in increase the accuracy of color recognition. On the other hand, 16 photodiodes of the same color are connected in parallel and evenly distributed. In the diode array, the positional error of the color can be eliminated. Photodiodes are 120 µm x 120 µm in size and are 144-µm centers.
The full-scale output frequency of this color sensor can be scaled by one of three preset values via two control input pins. In operation, the required filters are dynamically selected by two programmable pins. The sensor can produce a typical output frequency ranges from 2 Hz to 500 kHz. Users can also select 100%, 20% or 2% output scaling factor or power-down mode via two programmable pins. The output scaling factor allows the sensor's output to adapt to different measurement ranges and improves its adaptability. For example, when using a low-speed frequency counter, a small scaling value can be selected to match the output frequency of the TCS 230 to the counter. 
The color recognition sensor TCS3200 is upgraded version of the  TCS230, that the effect is better.
