Yancolor transfersensorprinciple

TCS230Using an 8-pin SOIC surface-mount package, 64 photodiodes are integrated on a single chip. These diodes are divided into four types. 16 of the photodiodes are equipped withRed filter16 photodiodes withgreen filter16 photodiodes withBlue filterThe remaining 16 do not have any filters, which can transmit all the light information. These photodiodes are cross-arranged in the chip, which can minimize the inhomogeneity of incident ray radiation, thereby increasing the degree of color recognition; On the other hand, the 16 photodiodes of the same color are connected in parallel and evenly distributed in the diode array, which can eliminate the position error of the color. When working, the required filter is dynamically selected through two programmable pins. The typical output frequency of this sensor ranges from 2 Hz to 500 kHz, and the user can also choose from two programmable pins, a 20% or 2% output scaling factor, or a power-off mode. The output scaling factor allows the output of the sensor to adapt to different measurement ranges, improving its adaptability. For example, when using a low-speed frequency counter, a small calibration value can be selected to match the output frequency of the TCS230 to the counter.

Product introduction:

3, power supply 3-5v
4, anti-light interference
5, white LED, can control the light, off.
6, can detect the color of non-luminous objects

7, PCB size: (L) 33mm * (W) 25mm

Select the channel of the color type through the serial port, and then determine the different colors because different colors correspond to different times (the same count value).
