Smart sensor is a new type of sensor that can sense and detect certain information of the measured object; can learn, reason, judge and process signals; and have communication and management functions. Smart sensors have the ability to automatically zero, calibrate, compensate, and collect data. Its ability determines that the intelligent sensor also has higher accuracy and resolution, higher stability and reliability, better adaptability, and is also very cost-effective compared to traditional sensors. So, what are the characteristics of smart sensors:

High precision

The smart sensor can eliminate the zero point through automatic zero calibration, and compare with the standard reference in real time to automatically calibrate the overall system and correct the system errors such as nonlinearity. Collect a large amount of data in real time for analysis and processing, eliminate the impact of accidental errors, and ensure the high precision of the smart sensor.

High reliability and high stability

Smart sensors can automatically compensate for the drift of system characteristics caused by changes in working conditions and environmental parameters, such as the drift of zero and sensitivity caused by fluctuations in ambient temperature and system power supply voltage; the range can be automatically changed after the measured parameter changes, real-time Carry out system self-inspection, analysis, and judge the rationality of the collected data, and automatically carry out emergency treatment of abnormal situations.

High signal-to-noise ratio and high resolution

Because the smart sensor has data storage, memory and information processing functions, through digital filtering and other related analysis processing, it can remove the noise in the input data and automatically extract useful data; through data fusion and neural network technology, it can eliminate cross sensitivity under multi-parameter states Impact.

Strong adaptability

The intelligent sensor has the functions of judgment, analysis and processing. It can decide the power supply of each part according to the working condition of the system, and the data transmission rate with the high/host computer, so that the system works in the optimal low power consumption state and optimizes the transmission efficiency.

Higher cost performance ratio

The high performance of the smart sensor is not obtained by pursuing the perfection of the sensor itself, carefully designing and debugging each link of the sensor, and performing "handicraft"-style craftsmanship like traditional sensor technology. The combination of microprocessor/microcomputer adopts cheap integrated circuit technology and chips and powerful software to realize it, so it has a higher cost performance.
