Overview
Sensors are essential devices in the information age and are widely used. They provide a primary means of obtaining information from the external environment. Human sensory organs alone are insufficient for studying natural phenomena and supporting many production activities, so sensors extend human senses and are sometimes referred to as "electronic senses".
With the arrival of the information era, obtaining accurate and reliable data is a primary concern. Sensors are the main means of acquiring information from natural and industrial environments. In modern industrial production, especially automated processes, various sensors are used to monitor and control parameters so equipment operates correctly and product quality meets requirements. High-quality sensors are therefore a fundamental element of modern production.
Key Features
Typical sensor characteristics include miniaturization, digitization, intelligence, multifunctionality, system integration, and network connectivity. These features not only support upgrades in traditional industries but also enable new types of industrial applications. Miniaturization is largely based on microelectromechanical systems (MEMS) technology, which has been successfully applied to silicon devices such as silicon pressure sensors.
Common Classifications

Trends
There are many sensor types, and specific applications often require specialized sensors. Third-generation sensors combine microcomputer technology with detection techniques, giving sensors a degree of embedded intelligence. A significant increase in intelligent sensors is expected in the coming years.
