Sensors are at the forefront of all industrial products, providing the first checkpoint to perceive the physical world. These sensors provide real-time monitoring, including the detection and reporting required for the process. Data monitored and collected by sensors is sent for control and analysis, and electrical signals are sent from the sensors to report any anomalies in a particular property. In this way, sensors can improve process efficiency and product quality while ensuring that processes are in line with best practices. Therefore, without a large number of excellent sensors, modern production will lose its foundation.

Key features of the sensor include: increased sensitivity for data capture, virtually lossless transmission, and continuous, real-time analysis. Real-time feedback and data analysis services ensure that processes are active and executed optimally.

Advances in sensing technology have given rise to today's smart sensors. Unlike traditional analog sensors, which have no active components, smart sensors contain circuitry that allows them to take measurements and output values as digital data. These sensors have an embedded microprocessor unit and a number of sensing devices are mounted on the signal converter. Smart sensors are capable of performing many intrinsic intelligent functions, such as the ability to self-test, self-validate, self-adapt, and self-identify. They understand process requirements, manage conditions, and can detect conditions to support real-time decision-making. These smart sensors are programmed for a wide range of process conditions, allowing performers to get the most bang for their buck.

China, United States, Germany and other countries have listed sensors as major scientific and technological projects in the future, and want to achieve technological breakthroughs in sensors, which is enough to show its importance.

The United World Chamber of Commerce has even made an evaluation: whoever dominates the sensor will dominate the new era.
