Application and new trends of sensor technology 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 in the world, and China already has about 7,000 kinds of conventional types and varieties. More than 90% of high-end sensors still rely heavily on imports, and digital, intelligent, and miniaturized sensors are seriously lacking. Compared with the international advanced level, my country's sensor basic technology is weak, and the production technology of related sensitive components cannot be broken, which has become an obstacle to technological upgrading. 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.

There are currently two major problems with IoT smart sensors. The first is interoperability. For smart homes to achieve real intelligence, there must be a good development, which must be dominated by interoperability, but now many in the market are still dominated by RF, which limits the development of smart homes; second It is the existence of unprofessional sensors. Many companies entering the smart home have not touched the sensor before. Therefore, the sensors produced only realize some epidermal functions, and many intractable diseases of the sensors cannot be solved. Target market.
With the rise of interconnection, the popularization of smart phones, wearables, virtual reality (VR), smart hardware, video interaction and security monitoring, robots, 4G/5G communication technologies, and their interconnection and intercommunication with homes are the development of smart homes. Opened up a brand-new space and brand-new user experience, the above-mentioned fields are also the hot areas of current sensors and applications.
With the development of high and new technology, smart home will experience three major development stages of "behind humans", "humanoids" and "surpass humans", and smart home applications will have a very broad space. At present, smart home control has been transformed from "manual operation + machine execution" semi-automation to "human-like" full automation, such as voice interaction, biometric recognition, brain wave recognition and other emerging technologies. In the not-too-distant future, smart homes will enter the era of full intelligence, through the precise collection of data, self-learning, precise analysis, intelligent judgment and other processes, so as to have wisdom beyond humans and realize true smart application scenarios.
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. It has no self-perception. Ability, unable to achieve true intelligence. 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 indoor and outdoor environment and weather. This achieves true humanity for smart homes. The foundation is created by chemistry. 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 into one through MEMS technology to realize the intelligentization, networking, integration and miniaturization of sensors. Networked sensors have the function of self-organizing networks to solve the cumbersome problems of smart home networking; intelligent sensors enable products with self-learning, self-calibration, self-testing and other functions to improve the degree of intelligence of the system; integrated sensors enable products with multi-parameter collection capabilities , To achieve fewer points to collect more information, 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.
