Color Recognition Sensor Module GY-33 TCS34725

Description:

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.

TCS347525

The TCS3472 device provides a digital return of red, green, blue (RGB), and clear light sensing values. An IR blocking filter, integrated on-chip and localized to the color sensing photodiodes, minimizes the IR spectral component of the incoming light and allows color measurements to be made accurately. The high sensitivity, wide dynamic range, and IR blocking filter make the TCS3472 an ideal color sensor solution for use under varying lighting conditions and through attenuating materials.

Introduction of Pins

Principle

LED lights up and illuminates the detected objects. The reflected lights detect the ratio of RGB via the filter and recognize the colors according to the RGB ratio. TCS347525 The TcS34725 light-to-digital converter contains a 3 X 4 photodiode array, four analog-to-digital converters (ADC) that integrate the photodiode current, data registers, a state machine, and an I2C interface. THE 3 X 4photodiode array is composed of red-filtered, green-filtered, blue-filtered, and clear (unfiltered) photodiodes. In addition, the photodiodes currents use a 16-bit digital value. Upon completion of a conversion cycle, the results are transferred to the data registers, which are double-buffered to ensure the integrity of the data. All of the internal timing, as well as the low-power wait state, is controlled by the state machine.

• Intelligent robot
• Teaching and laboratory instruments
