Sensors their applications

A sensor is a device device that can sense a prescribed measurement value convert it into a usable sensor output signal according to the law. Its input is a certain amount, it may be biomass, it can be a physical quantity a chemical quantity, its output is a certain physical quantity, which can be light electricity. The gas is equal. Due to its easy transmission, conversion processing characteristics, the output of the sensor is generally electricity, including voltage resistance current. Capacitance other forms. Sensor: The device usually consists of sensitive components, conversion components signal conversion circuits. Sensitive components can directly feel react to the tested person, output a certain physical relationship with the tested person. The conversion element can convert the sensing response of the sensitive element into an electrical signal; the signal conversion circuit can convert inappropriate power into a suitable power. The sensor only completes the basic conversion of measuring electricity. Then input the measurement control circuit for signal amplification, calculation, processing so on. Further conversion. Sensors are knowledge-intensive technology-intensive electronic components. There are many types. Several commonly used classification methods.

1) According to different working principles. Sensors can be divided into: vibration sensor, humidity sensor, magnetic sensor

Sensitive sensors, gas sensors, biological sensors, vacuum sensors, etc.

2) According to the measurement results. Sensors can be divided into: mechanical quantity sensor, thermal sensor, optical transmission sensor

Sensors, radiation sensors, gas sensors, gas composition sensors, liquid composition sensors,

Speed sensor, position sensor, liquid level sensor, etc.

3) Depending on the sensitive materials used. Sensors can be divided into: semiconductor sensing fiber

Sensor ceramic sensor. Metal sensors, etc.

4) Press to sense external information. Sensors can be divided into three categories: physical, chemical biological. based on

Physical effects such as light, electricity sound. Physical sensors that use magnetism, heat, etc.; based on chemical reactions

For example, chemical adsorption, chemical sensors using ion chemical effects; based on enzymes, antibodies, hormones

Biosensor with molecular recognition function.

5) Depending on the output signal. Sensors can be divided into: analog sensors. Digital sensor.

The sensor can convert all kinds of non-electricity into electric energy to realize non-electricity measurement technology,

Complex measurements cannot be achieved without sensors. Realize automatic detection automatic control in the system

The controlled part. Without the detection of the accused object, it is impossible to achieve control.

system.

With the continuous progress of science technology, sensors have been widely used in the defense industry, agriculture people's daily lives. It plays an increasingly important role in daily life, people's requirements for sensors are getting higher higher. This requires people to continue to develop new sensitive component materials. New processing techniques are used to improve

The measurement accuracy sensitivity of the sensor. The simple functions of traditional sensors are far being able to meet the needs of the development of modern society. The combination of sensor technology large-scale integrated circuit technology is required. The sensor has functions such as information storage, processing, self-diagnosis, self-detection, communication. Information control functions are becoming intelligent The direction of development. Traditional sensors are large in size high in power consumption. In order to meet the needs of modern automatic control systems, this requires sensors to develop in the direction of miniaturization integration. In today's information society, sensors have been widely used in various fields in national defense construction national economy.
