GY-33 TCS34725 Color Recognition sensor Replace alternative TCS230 TCS3200 - RS1124

The GY-33 is a low-cost colour recognition sensor module. Working voltage 3-5v, low power consumption, small size, easy to install. The working principle is that the illumination LED emits light, and after illuminating the object to be measured, the return light detects the RGB ratio value through the filter, and the colour is recognized according to the RGB proportional value. This module has two ways to read data, namely serial UART (TTL level) or IIC (2 lines). The baud rate of the serial port is 9600bps and 115200bps, which can be configured. There are two modes of continuous and inquiry output, and the settings can be saved after power down. There are 7 simple colour recognitions, no need to calculate RGB values. Can adapt to different working environments, and connect with single-chip computers and computers. The module can also set a separate sensor chip operating mode. As a simple sensor module, the MCU does not participate in the data processing.
