The sensor is the source of the information collection and transmission system. From a professional perspective, the sensor is often a key component related to system performance and performance indicators. The sensor is a component that can convert the content of the object detected by it from a non-electrical signal to an electrical signal and display it visually.
The sensor is a combination of science and engineering. It depends not only on the injection of new scientific phenomena and new laws, but also on the inheritance of new technologies and processes. Today, with the advanced technology, the classification of sensors is becoming more and more detailed. The following editors will take you to an overview of new types of sensors around the world.
Fiber optic sensor Fiber optic sensor, as its name implies, is a type of sensor manufactured using fiber optic components. Compared with traditional sensors, fiber optic sensors have the advantages of high sensitivity, strong anti-interference ability, corrosion resistance, good insulation, small size, light weight, simple structure, and low power consumption. Optical fiber sensors are suitable for toxic and harmful, fire and explosion-proof environments and remote distribution applications.
Optical fiber sensors can be divided into: functional optical fiber sensors, non-functional optical fiber sensors, optical fiber temperature sensors , optical fiber displacement sensors, optical fiber concentration sensors, optical fiber current sensors, optical fiber flow rate sensors, light-emphasized optical fiber sensors, phase modulation optical fiber sensors, Frequency modulation fiber optic sensors, polarization modulation fiber optic sensors, and wavelength (color) modulation fiber optic sensors.
Integrated sensors are sensors that use integrated circuit technology to integrate semiconductor components and information measurement processing circuits on a chip through integrated circuit technology. The main features of the integrated sensor are good function targeting, small measurement error, fast response speed, low price, long transmission distance, small size, and micro power consumption. The integrated sensor is suitable for long-distance measurement and long-distance control. Non-linear calibration is not required, and the peripheral circuit is simple.
Integrated circuit sensors are divided into: integrated temperature and humidity sensors , integrated carbon dioxide sensors , integrated ammonia detection sensors, integrated H2S gas detection sensors, integrated soil humidity sensors, and so on.
MEMS is the English acronym for Microelectro Mechanical Systems, and is generally referred to as MEMS. It is a popular field of multidisciplinary development based on microelectronic technology. MEMS sensor is a new type of advanced sensor developed and manufactured using microelectronic technology and micromachining technology. It has the characteristics of small size (micron level), high reliability, light weight, low power consumption, suitable for mass production, easy integration and intelligentization. Due to the special properties of MEMS sensors, we mainly use them in the medical, automotive, and motion tracking industries.
MEMS sensors are currently our first technology to be developed. Today's research directions are roughly: MEMS pressure sensors, MEMS acceleration sensors, micromechanical gyros, MEMS gas sensors, MEMS temperature sensors , resonant fluid density sensors, vacuum sensors, etc .
