Color is one of the utmost significant characteristics of light which can be used to identify various aspects of the object. Color sensors are classified under the photoelectric sensors and these sensors are capable of analyzing the color of the surface by analyzing the wavelength of the light reflected from the surface. A typical color sensor uses a high-intensity white LED to project modulated light on the target. The reflection of this light from the target is subsequently analyzed for red, green and blue color constituents and their intensities.
These sensors are programmed by holding a sample in front of the sensors and fine-tuning it to match for that specific color. After multiple trials the sensor is re-adjusted considering high and low values to establish an acceptable color range. In the case of a multiple channel sensor, the sensor is programmed to identify one color in each channel.
The color sensors find use in many end user industries that include consumer and commercial printing, health and wellness, fluid and gas analysis, lighting and digital signage, consumer electronics and industrial automation.
Among the multiple uses of color sensors the most interesting is in assembly lines; they are widely used on assembly lines to detect various components based on their colors. However, the major challenge was to detect the subtle difference among very similar and highly reflective colors and also in detecting small round objects. These challenges grow multi-fold when the components use metallic paints or mirrors. However, this drawback has been reduced considerably by advancements in technology.
The color detection systems have many advantages over the other systems that have similar functionality. Few of the advantages of color sensors include- they are cost effective and easily replaceable. They can be easily reprogrammed depending on the requirement. Moreover, they can also differentiate luminescence surfaces and also transparent objects.
The wide spectrum of application of color sensors make it a perfect match for many industries including food & beverage, pharmaceutical, automotive and textile among many others. As per a latest study by an Indian based Market Research Firm IndustryARC, the market for color detection sensors
is estimated to reach $3.1 billion by 2021.Browse Related Reports:
