集成度更高、更加智能化、体积更小是未来传感器发展的必然趋势,这也就意味着其将满足更多行业、领域和场景的应用要求,安装也更为方便。同时,为适应智能制造的发展,智能化也更加成为传感器发展的重要方向。智能化就是传统传感器的“感知”能力被重新定义,并赋予“分析”和“发出指令”。
Higher integration, intelligence, and smaller size are inevitable trends in the development of sensors in the future, which means they will meet the application requirements of more industries, fields, and scenarios, and installation will also be more convenient. At the same time, in order to adapt to the development of intelligent manufacturing, intelligence has also become an important direction for the development of sensors. Intelligentization refers to the redefinition of the "perception" ability of traditional sensors, and the empowerment of "analysis" and "issuing instructions"。
