The origins of sensor processors can be traced back to early scientific research and technological developments. The perception and observation of the external environment have long been fundamental requirements for human survival and progress; consequently, people began to experiment with various methods and tools to sense and measure external physical quantities and parameters.
The earliest forms of sensor processors can be traced back to antiquity-specifically to ancient measuring instruments such as spirit levels and compasses-which perceived information about the external environment by observing the position and orientation of objects. As science and technology advanced, people began to develop a wide array of new types of sensors.
The development of modern sensor processors began in the 19th century, when scientists started applying electrical principles to achieve sensing and measurement capabilities. For instance, devices such as resistive sensors and potentiometers are examples of sensors that utilize electrical principles for perception. Driven by advancements in electronics and materials science, both the variety and performance of sensors have continuously improved.
In tandem with the evolution of computer technology, sensor processors have gradually integrated with computing and communication technologies to form intelligent sensing and control systems. Modern sensors encompass a diverse range of types-including optical sensors, pressure sensors, temperature sensors, and accelerometers-and are now widely deployed across various fields, such as industry, agriculture, healthcare, and transportation.
