with the development of science and technology, all industries are inseparable from intelligent industry, intelligent agriculture, intelligent transportation, to intelligent logistics, intelligent security and other fields. the demand for intelligence in various fields, in essence, is the increasing demand for information. sensor has become one of the most important electronic devices, especially the intelligent sensor which can collect, process, analyze and transmit information.
in information consumption, accurate and timely information sources, large coverage density and wide area are the basis, and sensor is one of the most important media. traditional sensors can meet this demand, but the previous sensors can not analyze and process the information, which is fatal to the electronic components requiring intensive performance, so intelligent sensors emerge as the times require.
the intelligent sensor combines the sensor and the microprocessor closely by means of technology. the sensor and its signal conditioning circuit are integrated with the microprocessor on a chip, which can be called a sensor with preliminary intelligence. intelligent sensor combines asic circuit, microprocessor, communication interface and software protocol with sensitive chip to make full use of sensing information of sensitive chip. integration, miniaturization, multi-function, intelligence and networking are the development trend of sensors, but integration and miniaturization are the basis of this trend. only by integrating and miniaturizing technology can we realize low cost, low power consumption, high performance, multi-function, intelligence and networking.
at present, intelligent sensor is the hotspot and frontier of sensor research in the world. the main bottleneck of the development of domestic sensor industry towards miniaturization and integration is the lack of capacity of china's ic and mems technology industry chain. there is a big gap between china's ic and mems technology industry chain in terms of technical quality, production capacity and production scale. to vigorously carry out the research on intelligent sensors is a leap forward development idea that china should adopt, a key measure to occupy the commanding heights of information technology in the future, and also for the development trend of sensors.
