The photoelectric sensor realizes control by converting changes in light intensity into changes in electrical signals.

The photoelectric sensor is generally composed of three parts: light source, optical path and photoelectric element. The measured change is converted into a change in an optical signal, and then the optical signal is further converted into an electrical signal with the help of a photoelectric element.
The four major areas of photoelectric sensor application are industrial and automotive electronics, communication electronics, and special equipment for consumer electronics. Among them, the sensor market in the industrial and automotive electronics fields accounts for about 42%. With the development and popularization of Internet of Things technology in the future, the application of photoelectric sensor will penetrate into all aspects of human life.
The future development direction of photoelectric sensor will have the following points:
Highly integrated
The photoelectric sensor manufacturer tells you that due to the increasingly tight design space, cost and power budget, integrating multiple sensitive components on the same substrate and making a multi-functional combined MEMS sensor that can detect multiple parameters has become an important solution.
Low power consumption
The photoelectric sensor manufacturer tells you to reduce the power consumption of the sensor, use environmental energy harvesting to realize self-supply energy, and the demand for enhanced endurance will accompany the development of the sensor, and it will become stronger day by day.
miniaturization
The photoelectric sensor manufacturer tells you that the miniaturization of the sensor means that the characteristic size of the sensitive element is "millimeter (mm)-micrometer (um)-nanometer (nm)" type sensor. This type of sensor has the advantages of miniaturization in size and performance, integration of elements and diversity of uses, functional system and structural complexity. The photoelectric sensor manufacturer tells you that the miniaturization of the sensor is not only the miniaturization or reduction of the feature size, but a high-tech micro-system with new mechanisms, new structures, new functions and new functions. The preparation process involves MEMS technology, 1C technology, laser technology, precision ultra-fine processing technology, etc.
Intelligent
Technological development shows: photoelectric sensor manufacturers tell you that the digital signal processor (DSP) will promote the development of many new and next-generation sensor products. With the development of 5G communication, big data, AR, VR, cloud computing, etc., as well as the application of new technologies such as robot internal driving and artificial intelligence, the world has entered the era of intelligence from the original electric era, and sensors have also ushered in a new era. The era of intelligence.
High sensitivity
Photoelectric sensor When a person or object enters the sensing range (reflection point, small angle) directly in front of the sensor, the sensor immediately outputs, and the sensor immediately turns off the output after the person or object leaves. For example, in the intelligent lighting, the lights can be turned on when people come and the lights are off when people go, thereby effectively ensuring the quietness of the living space in the building.
