[ Focus on Chemical Machinery Equipment Network ] On March 23, the Innovative Integrated Circuit and Smart Sensor Technology Forum and Joint Laboratory Signing Ceremony was held in Beijing.
The participating experts conducted in-depth discussions on issues related to the development of innovative integrated circuits and smart sensor technology.
Both integrated circuits and sensors are cross-disciplines, featuring high integration, high precision, and high innovation.
The domestic alternative road is bound to gather national strategic scientific and technological forces, focus on major core technical issues, build a multi-disciplinary and in-depth research highland for scientific research, and strengthen the sincere cooperation and collaborative innovation between scientific research teams and enterprises.

 

Some commonly used smart sensors can greatly improve the convenience and safety of life.
The following editor will give you an inventory of how these sensors help smart homes provide services for everyone.

 

Smart home application of sensors
 

Sensors are the main ways and means to obtain information in the fields of nature and production, and their role cannot be underestimated.
Then the sensors to ensure people's health and home safety have become the most powerful weapon.

 

1.
Motion sensor
 

For users who are familiar with home security systems, the motion sensor is not unfamiliar.
It allows you to know every move in or around your home at any time.
Once there is some "turbulence", it will send warning information to the owner's mobile phone.
When the motion sensor senses the moving object, it can trigger the monitoring device to take photos and videos of the moving object, and send the video or picture to the user's mobile phone; it can also cooperate with the light to automatically turn on the lighting equipment when it senses the arrival of someone Wait.

 

2.
Temperature and humidity sensor
 

Appropriate temperature and humidity can also bring users a comfortable living environment.
Although some electrical equipment also has built-in temperature and humidity probes, after all, the monitoring range is limited and it is difficult to monitor every corner of the home.
Therefore, temperature and humidity sensors can make up for this lack.
Bring environmental feedback to the home and create a comfortable living environment.

 

3.
The air sensor protects healthy air
 

　　The air problem has always attracted much attention.
People will live at home for a long time, and the quality of the air environment will also affect the health of their families.
The air sensor can monitor the monitored environment in real time for the user.
Once the safety index is exceeded, the air purification equipment in the home can be triggered to purify the air and create a healthy air environment for the family.

 

　　Real home intelligence is far from enough to rely on smart phones and smart routers, and a large number of sensors are needed as support.
Therefore, basic research and technological innovation of sensors are very important.
At present, smart sensors are developing from the separation of sensing, storing and computing to the integration of sensing, storing and computing.
Because the integrated smart sensors of sensing, storing and computing have the advantages of small size and high energy efficiency, they will be deployed in a large number of intelligent networking and artificial intelligence applications in the future.

 

　　The new trend of sensors in the field of smart home
 

　　In the IoT era, sensors are the core of the perception layer of the Internet of Things and a key element that constitutes the Internet of Things.
At present, there are about 22,000 kinds of sensors.
China already has about 7,000 conventional types and varieties.
More than 90% of sensors still rely heavily on imports, and digital, intelligent, and miniaturized sensors are seriously lacking.
Compared with the * level, my country's sensor basic technology is weak, and the production technology of related sensitive components cannot be broken through, which has become an obstacle to technological upgrading.

 

　　There are two major problems with IoT smart sensors.
*It is interconnection and interoperability.
For smart homes to achieve real intelligence, interconnection and interoperability must be the leading factor; the second is the existence of unprofessional sensors.
Many companies that enter smart homes have not touched sensors before, so they produce The sensor that comes out only realizes some epidermal functions, and puts on the market if many intractable diseases of the sensor cannot be solved.

 

　　With the rise of interconnection, the popularization of smart phones, wearables, virtual reality (VR), smart hardware, video interaction and security monitoring, robots, and 5G communication technologies, as well as their interconnection with homes, has opened up the development of smart homes.
With a brand-new space and a brand-new user experience, the above-mentioned fields are also hotspots of current sensors and applications.

 

　　For smart homes, sensors play the equivalent of human eyes, ears, noses, etc.
, and are the entrance to all analysis data.
A smart home system without a sensor system is undoubtedly a "disabled" system.
Sensors and their solutions can continuously judge the user’s body and life status, deep-learn the user’s preferences, continuously monitor the user’s vital signs, monitor the status of home equipment, and the environment and weather indoors and outdoors, which is truly humanized for smart homes Created the foundation.
In the future, sensor technology will be more precise, precise and rapid.
The so-called precision is to provide the system with corresponding and effective data, that is, there will be no false positives, false negatives, etc.
; precision is to provide data with higher precision and smaller error range to ensure that the data will not be distorted; rapid means high response sensitivity, Respond quickly to meet the needs of smart home application scenarios.

 

　　With the development of science and technology, sensors are developing in the direction of intelligence, networking, integration, and miniaturization.
Especially the maturity of MEMS technology is constantly promoting the progress of sensor technology.
The sensor chip, processor chip, communication chip, and circuit are integrated through MEMS technology to realize the intelligentization, networking, integration and miniaturization of sensors.

 

　　Summary
 

　　The progress of sensors has promoted the progress of smart homes.
For example, networked sensors have self-organizing network functions to solve the cumbersome problems of smart home networking; smart sensors enable products to have functions such as self-learning, self-calibration, and self-testing, and improve the intelligence of the system Degree; integrated sensors enable products with multi-parameter collection capabilities, reduce installation costs, and improve overall aesthetics; miniaturized sensors make the design of terminal products more flexible and easier to integrate into traditional home appliances, promoting the intelligent transformation of traditional home appliances .

 

　　In the era of the Internet of Things, sensor technology is both an opportunity and a challenge.
The Internet of Things era provides a broader application space for sensors, but also puts forward more requirements for sensors, such as smarter, smaller size, higher integration, lower system power consumption, and segmentation for various industries solution.
