Intelligent sensor is to replace and biological sense organs and expand its function and design of a kind of device. And the feeling of organisms, there are two basic functions: one is the test object or object detection transformation of signal; Another kind is to judgment and reasoning, appraise the state of an object. The former is called “awareness”, while the latter is called the “cognitive”. General sensor only “sense” an object accurately, and don’t have the ability to “know” (wisdom). Smart sensors can be “perception” and “cognitive”, have the effect of man’s “five senses” function.
Smart sensor to meet the following conditions:
1, containing specific algorithm can be used according to need to change;
2, random setting and adaptive;
3, a signal processing (such as temperature compensation, linearization, etc.);
4, with a certain amount of storage, recognition and the diagnostic function;
5, eliminating outliers and exceptional value by sensor itself, provide more comprehensive, more real than traditional sensors information;
No matter what kind of definition illustrates the main characteristics of intelligent sensor is sensitive to the combination of technology and information processing technology. That is to say, the intelligent sensor must have the ability of “perception” and “cognitive”. If you want to have information processing ability, must want to use computer technology, intelligent sensor volume into consideration, nature can only use the microprocessor, etc.

In today’s highly developed information technology, intelligent sensor and muti_function change will become the important direction of the sensor. Compared with the traditional sensor, intelligent sensor has the following advantages:
1, with functions of configuration. Can realize multiple sensors, multi-parameter composite measure, expanding the scope of the test and use.
2, has the memory and storage function. Testing data access at any time, to speed up the information processing.
3, with adaptive, self adjustment function. According to the numerical size of physical quantities under test and the choice of automatic detection range and measuring the changes of way, improve the detection of applicability.
4, with functions of logic judgment, statistical processing. To analyze the test data, statistics and correction, but also can be linear, nonlinear, temperature, noise, response time, cross induction and slow drift error compensation, to improve the measurement accuracy. Best ability net belongs to the work group, is a leading domestic electronic industry service platform, online provide components, customized procurement, PCB, BOM with single sensor, the electronic industry, such as material selection, supply chain solutions of a complete set of, meet the demands of electronic industry of small and medium-sized customers comprehensive one-stop.
5, with functions of self-diagnosis, self calibration. Can be boot self-checking, in switching power supply can be run at work self-inspection, and can be real-time diagnostic test to determine which of its own component failure, improving the working reliability.
6, with functions of data communication. Intelligent sensor having interface of data communication, can with the computer directly online, mutual exchange of information, improve the quality of the information processing. Computer software plays an important role in smart sensors. Because of the addition of “computer”, smart sensors can be information through all kinds of software testing process management and adjustment, to make it work in the best condition, so as to enhance the function of sensor, improve the performance of the sensor. In addition, the use of computer software to achieve the realization of hardware function, because by replacing parts of the hardware and software can reduce the production difficulty of sensors.
