Colour Sensor

A colour sensor is a device that detects and measures an object's or surface's colour. Color sensors measure the amount of light reflected or transmitted by an object in various wavelength bands. RGB (red, green, blue) sensors detect the intensity of light in the red, green, and blue areas of the spectrum, whereas CMYK (cyan, magenta, yellow, black) sensors measure the intensity of light in the cyan, magenta, yellow, and black regions of the spectrum.

White light is a mixture of three basic colors known as primary colors. They are red, blue and green. These colors have different wavelengths. Combinations of these colors at different proportions create different types of colors. When the white light falls on any surface, some of the wavelengths of the light are absorbed by the surface while some are reflected back based on the properties of the surface material. Colour of the material is detected when these reflected wavelengths fall on the human eye. A material reflecting wavelengths of red light appears as red. The component used to detect colors is the Color sensor.

What is a Color Sensor?

A color sensor detects the color of the material. This sensor usually detects color in RBG scale. This sensor can categorize the color as red, blue or green. These sensors are also equipped with filters to reject the unwanted IR light and UV light. 

Working Principle of Color Sensor

To detect the color of material three main types of equipment are required. A light source to illuminate the material surface, a surface whose color has to be detected and the receivers which can measure the reflected wavelengths.

Colour sensors contain a white light emitter to illuminate the surface. Three filters with wavelength sensitivities at 580nm, 540nm, 450nm to measure the wavelengths of red, green and blue colors respectively.

1.What is a color sensor?

  • A colour sensor is a device capable of detecting and measuring various colours in the visible spectrum. It can be used to detect the presence of a specific colour or to measure the colour of an object. Color sensors analyse the light reflected or emitted by an item and use this information to identify the colour of the object.

2.How does a color sensor work?

  • A colour sensor generally measures the quantity of light in different sections of the visible spectrum using one or more sensors. The sensor then compares these data to a pre-defined set of colours and outputs the closest match. Some colour sensors employ numerous sensors to detect light in various sections of the spectrum, whilst others employ a single sensor plus a filter to measure various colours.

3.What are some common applications of color sensors?

  • Color sensors are used in a variety of applications, including quality control in manufacturing, colour matching in printing and textiles, colour measurement in paint and ink, colour recognition in robots, and many more. They are also used in consumer electronics products such as smartphones and tablets to alter colour temperature and white balance, as well as cameras for colour balance and metering.
