In the IoT era, sensors are at the heart of the Internet of Things perception layer and form the key element of the Internet of Things. At present, there are about 22,000 kinds of sensors in the world. China already has about 7,000 types and varieties of conventional products. Over 90% of high-end sensors are still heavily dependent on imports. Digitization, intelligent and miniaturized sensors are seriously lacking. Compared with the international advanced level, China's sensor technology is weak and the related sensitive components manufacturing technology can not be broken, which has become an obstacle to technological upgrading. BoschSensortec Asia market and business development director Yan really think that in the Internet of things, sensor technology is both an opportunity and a challenge. The IoT era offers a lot of room for sensor applications, but also places additional demands on sensors such as smarter, smaller form factors, higher integration, lower system power consumption, and industry-specific segmentation solution. The Internet of Things sensor technology is both an opportunity and a challenge Liu Hai, general manager of Shenzhen Haiman Technology Co., Ltd. said in an interview that IoT smart sensors now exist two major issues. The first is interoperability, smart home to achieve true intelligence, there is a good development, must be based on interoperability as the dominant, but now on the market or a lot of RF-led, limiting the development of smart home; the second Is not professional sensors exist, many companies into the smart home, many have not touched the sensor, so the sensor is produced only to achieve some of the functions of the epidermis, for the sensor there are many incurable diseases can not be solved Target market. In the Consumer Security Sensor (Shenzhen) Co., Ltd. product manager Wang Jia view, IoT era, the application scene more and more things, for some areas, such as sports, aerospace and other sophisticated areas , Their requirements for the sensor products are extremely strict, which will guide the performance of certain sensor products such as the performance of the ultimate trend of development. Sensor is the sensor of smart home With the advent of the Internet, smartphones, wearables, VR, smart hardware, video interaction and security monitoring, the popularity of robots, 4G / 5G communications technology, and their interoperability with home, for the development of smart home Opened up a new space and a new user experience, the above-mentioned areas are also the current sensor and application of hot areas. With the development of high and new technology, smart home will experience three major development stages of "falling behind people," "people being like," and "surpassing people". The smart home application will have a vast space. At present, smart home control has shifted from semi-automatic "manual operation + machine execution" to fully automated "humanoid" such as emerging technologies such as voice interaction, biometrics, and brainwave identification. In the near future, smart home will enter the era of all-intelligence, through the precise data collection, self-learning, accurate analysis, intelligent judgment and other processes, which have surpassed the wisdom of people to achieve a real smart scenarios. For the smart home, the sensor plays a role equivalent to the human eye, ears, nose, etc., is the entrance of all the analysis of data, without the sensor system smart home system is undoubtedly the "disability" system, it does not have the self-perception Ability to achieve true intelligence. Sensors and solutions can continuously determine the user's body and state of life, learning the depth of user preferences, continuous monitoring of the user's vital signs, monitoring the status of household equipment and indoor and outdoor environment and weather, this smart home real humanity To create a foundation. In the future, sensor technology will be more accurate, accurate and rapid. The so-called precision is to provide the system counterparts, valid data, that is, not false positives, omissions and other cases; accurate is to provide higher accuracy, smaller error range of data to ensure that the data will not be distorted; rapid is the reaction of high sensitivity, Fast response to meet the needs of smart home application scenarios. Taking gas detection as an example, under the development of smart air technology, smart home will move towards the direction of smart interconnection. The premise of smart interconnection is to perceive various information such as people, environment and equipment. Then, the smart home system, based on the acquired information and people Experience, automatically make the most reasonable adjustments to achieve intelligent interconnection of all things. The role of sensors in the smart home system is the acquisition of a variety of information, the smart home system is the key to the correct implementation of linkage. Formaldehyde gas concentration measured by the gas sensor, PM2.5 concentration measured by the PM2.5 sensor, and intelligent home air purifier by the smart home system based on the collected formaldehyde concentration and PM2.5 concentration. After Hyman Technology's visit to customers that the current smart home system, security, fire sensor is just need smart home. Sensor technology is the key to miniaturization and sensitivity With the development of science and technology, sensors are moving in the direction of intelligence, networking, integration and miniaturization. In particular, the maturity of MEMS technology is driving the advancement of sensor technology. The sensor chip, the processor chip, the communication chip, and the circuit are integrated by the MEMS technology to realize the intellectualization, networking, integration and miniaturization of the sensor. Network sensors with self-organizing network capabilities to solve the tedious problems of intelligent home networking; intelligent sensors make products with self-learning, self-calibration, self-test and other functions to improve the system's intelligence; integrated sensor makes the product with multi-parameter acquisition capability , To achieve less cloth collection more information, reduce installation costs and improve overall aesthetics; miniaturization of the terminal design allows more flexible products, but also easier to integrate into traditional home appliances, to promote the intelligent transformation of traditional home appliances. In the development of sensing technology, Hayman Liu Ya believes that the main breakthrough from the two aspects of technology. First, the power consumption of the sensor, the current sensor to use more battery-powered, if the frequent replacement of the battery will affect the user experience, to solve the problem of power consumption, so that the sensor 10 years battery will greatly enhance the user experience; Is the distance of wireless communication. At present, the mainstream wireless technologies transmit relatively short distances in the indoor area. In the case of larger houses, the communication distance needs to be extended through the relay, and increasing the relay inevitably increases the cost. The development of the sensor should be toward the direction of increasing the sensitivity, because the smart home product application scenario has its particularity compared with other fields, so the sensitivity of the sensor is a key measurement factor. If you want to create a better user experience, this aspect must There is a big leap. In addition, the accuracy and accuracy of the sensor is an inevitable requirement for the development of smart home for the realization of all-intelligent applications such as cloud computing and big data analysis. In the future, the collection of sensor data volume will be more complicated, more diverse and more large Therefore, we must ensure the accuracy and reliability of the data. In addition, Bosch strictly says that with the popularity of environmental sensors in smartphones, wearable devices, and home appliances, environmental sensors will be breakthroughs in smart home automation and user-friendly applications as well as in environmental monitoring applications. With the sport and fitness The health sensor application will popularize and interact with smart phones, wearable and home health fitness equipment, and the family health and medical experience will further improve. With the popularization of VR applications, the home entertainment experience will also be rebuilt. Environmental sensors and smart home automation and user-friendly applications will be a breakthrough.
