Technical Field

The application relates to the technical field of sensors, in particular to a color code sensor and an assembly method thereof.

Background

Currently, a color scale sensor is a sensor for detecting, discriminating, and measuring the color of an object. The working principle of the color code sensor mainly comprises the processes of light source emission, object reflection, photosensitive element receiving, signal processing and the like. It can realize the identification and measurement of different colors through different optical filters, color spaces and algorithms. Color code sensors are widely used in the automation field, such as object recognition, quality control, and sequencing tasks on industrial production lines. The color recognition method can quickly and accurately recognize the color of the object and perform corresponding operation according to the color information.

The color scale sensor is generally composed of a light emitter, a photodiode, a photosensitive element, a signal processing circuit, an output interface and the like. The light emitter is typically a light source, such as an LED, for illuminating the object under test. The photosensitive element may be a photodiode, a photoresistor, a phototransistor, or the like, for receiving a light signal reflected or transmitted by the object under test. The optical signals received by the photosensitive element are processed by the signal processing circuit, converted into electric signals, and output to external equipment for analysis and processing through the output interface.
