Use much, see less: What happens to the world without sensors?
When you lift the sensor, you usually hear more about it and see less. In fact, with the development of sensor technology, its application scene has penetrated into the military, energy, robotics, automatic control, environmental protection, transportation, medical and chemical, household appliances and remote sensing technology, playing the human senses, nerves, and brain. Character.
1. Application of sensors in the aerospace field
In addition to the use of sensors for speed, acceleration and flight distance measurements, the spacecraft's direction of flight, flight attitude, flight environment, state of the aircraft itself, and monitoring of internal equipment are also detected by sensors, as well as the internal environment of the spacecraft (eg Humidity, temperature, air content, etc. are all detected by sensors.

In addition, remote sensing technology is used for large-scale detection of measured objects and their states in a large area over long distances from aircraft, satellites, spacecraft and ships.

2. Application of sensor in robot
In places with high labor intensity or dangerous work and some high-speed, high-precision work, robots have been gradually used to replace people's work. However, in order to make the functions of robots and people closer, it is necessary to install visual sensors and tactile sensors for the robots, so that the robot can visually recognize and detect objects, and generate tactile, force, sliding feeling and weight through the sense of touch. feel.

3. Application of sensor in industrial automatic control system
The sensor is the primary part of automatic detection and automatic control. If there is no accurate and reliable measurement of the original information (signal or parameter) by the sensor, it is impossible to automate the extraction, conversion and processing of the signal to the production or control process. It can be seen that the sensor is essential in the automatic control system.

4. Application of sensors in environmental protection
Global air pollution, water pollution and noise have seriously damaged the earth's ecological balance and the environment we rely on. In order to protect the environment, various environmental monitoring instruments made of sensors are playing an active role. If the water quality is monitored by a biosensor, the detection of the amount of sewage in the sewage monitoring system, and the identification of the sewage component are all monitored using sensors.

5, the application of sensors in medicine
The sensor can be used medically to perform difficult diagnosis on the surface and internal temperature of the human body, blood pressure, intracavitary pressure, blood and respiratory flow, tumor, blood analysis, pulse and heart sound, and heart and brain waves. It plays a wide-ranging role in early diagnosis, early treatment, long-distance diagnosis, and development of artificial organs.

6, the application of sensors in transportation
Sensors are also widely used in transportation. Sensors are used to detect axle number, wheelbase, vehicle speed monitoring, vehicle classification, dynamic weighing, toll booth scale, red light photography, parking area monitoring, traffic information collection (road monitoring). ) and the airport taxiway. In the vehicle, it is not only limited to the monitoring of driving speed, driving distance and engine rotation speed, but also for safety monitoring, such as car airbag system, anti-theft device, anti-skid control system, anti-lock device, electronic shift control device, Exhaust circulation devices, electronic fuel injection devices, and automotive "black boxes" have all been put into practical use.

7, the application of sensors in daily life
Sensors are everywhere in our daily lives, such as sensors used in household appliances: refrigerators, temperature sensors in rice cookers, temperature and humidity sensors in air conditioners, liquid level sensors in washing machines, gas leak sensors in gas stoves. , infrared remote control in water meters, electricity meters, televisions and DVD players, light sensors in cameras, fuel gauges and speedometers in automobiles, etc.
▲ sensor application in smart home
According to statistics, the overall market size of China's Internet of Things will reach 750 billion yuan by 2016, and the sensor industry will directly benefit from it. At present, there are more than 1,700 companies engaged in the production and research and development of sensors in China, among which Senba is a minority in China. Mastering the production formula and process of pyroelectric infrared sensor core materials, and having one of the independent intellectual property rights, it has a significant competitive advantage in the industry and will become a leader in the photoelectric sensor industry.
