7. Model sensor

Model sensor, as its name implies, is able to use a model to describe the actual sensor characteristics and the process of the sensor. It is also called a sensor that can build a model. Many circuits or physical products are verified or expressed by models with special properties or special shapes before production. The model can be a circuit model, a network model, a mathematical model, a data model, a physical model, or a program model.

The use of mathematical models can make it easier for developers to use mathematical analysis methods to analyze and understand the performance of sensors and the construction of sensor systems, and provide a solid foundation for the optimal design of sensor performance. For example, the mathematical methods of differentiation and differentiation can analyze the sensitivity and stability of the sensor test, which is helpful for the R & D personnel to find the structural parameter values. The use of network models is conducive to R & D personnel's simulation experiments and analysis, and is conducive to improving sensor design and system performance characteristics. The program model is convenient for R & D personnel to use computer to analyze performance indicators and simulation design. The data model is helpful for developers to verify the authenticity of the parameters. The inverse model can compensate for sensor performance defects and signal distortion caused by the external environment in actual testing. The ultimate purpose of compensation is to improve the accuracy of the sensor and expand the dynamic range and frequency response range of the sensor.

8. Network Sensor

A network sensor is a sensor that is equipped with a network interface when the sensor is designed. The network interface uses a microprocessor to implement its functions, so it is also called an intelligent network sensor.

网络传感器

This sensor can be used as a terminal of a metropolitan area network (MAN), a local area network (LAN), a wide area network (WAN), and the Internet. It accesses network node computers, other instruments, and sensors and other terminal equipment through a network interface, and directly exchanges and shares data with it. . Network sensors are suitable for remotely distributing measurement data and controlling equipment. For this type of network sensor, manufacturers do not need to build a variety of custom interfaces that support specific network protocols. Standard wired and wireless connection methods are also used between the sensor interface and the network interface. Since the interface module and the network interface module of the sensor produced by the manufacturer are all in accordance with the standard supporting parts, the sensor system and the network can be plug and play.

9. Biosensor

Biosensors are sensors designed using specific bio-sensitive components. Bio-sensitive elements mainly include active biological materials such as antigens and antibodies, enzymes, nucleic acids, cells, tissues, and microorganisms. It is based on the chemical reaction of substances in the body to convert the measured parameter into a non-electrical physical quantity, and then uses a general physical sensor to The electrical signal is converted into an electrical signal suitable for remote transmission and convenient for subsequent processing to complete its measurement.
