As one of the three major sensor exhibitions in the world, the China (Shanghai) International Sensor Technology and Application Exhibition is known as the wind vane for the development of the global sensor industry. Each exhibition will display tens of thousands of industry-leading sensing new technologies and new technologies. product. This year, the 8th China (Shanghai) International Sensor Technology and Application Exhibition set sail from September 13th to 15th at the Shanghai Transnational Procurement Convention and Exhibition Center. At this exhibition, new products in the field of intelligent sensing such as vehicle-mounted sensing, laser and flexible sensing attracted attention.
In recent years, the automobile industry has accelerated its development. my country has successively introduced a series of policies to strongly support the development of smart cars and new energy vehicles. The number of smart cars and new energy cars has increased significantly. On the one hand, consumers demand a more comfortable, healthier and safer driving experience, so functions such as in-car air quality detection and battery pack thermal runaway monitoring have become standard features for smart cars and new energy vehicles. On the other hand, the safety protection capabilities of automobiles need to continue to be improved, which brings new opportunities for the development of related automobile sensors.
Among the comfort automotive sensor products, vehicle-mounted sensors can monitor the air quality in the environment inside and outside the vehicle in real time, including monitoring the carbon dioxide concentration and PM2.5 concentration in the cockpit. Among safety automotive sensor products, it is possible to monitor the CO2, CO, VOC gases and temperatures released before thermal runaway triggering of lithium batteries, and transmit the measurement signals to the battery management system in real time to achieve early warning and effectively improve improve the safety of new energy batteries. It is understood that many well-known car companies have already applied these on-board smart sensors in some new energy models.
How to ensure the safety of household gas is a topic that the whole society is always paying attention to. Timely monitoring of gas leakage through technical means is an important measure to ensure the safe use of gas. Laser sensors were once used in military, medical, and high-end industrial fields due to their characteristics such as accurate detection and fast response speed. Nowadays, laser technology is accelerating its penetration into the civilian field. High-end household gas alarms have already used advanced laser technology. Due to its strong anti-interference ability, low power consumption, long life, and high reliability, laser methane household gas alarms have been recognized by the market not long after they were launched.
At this exhibition, we also saw the laser methane household gas alarm. Its biggest highlight is that the core component of the household laser methane sensor module adopts advanced laser detection technology. This product has strong anti-interference ability and is not afraid of water vapor and temperature and humidity changes in the kitchen. It responds quickly and detects accurately with zero false alarms. When necessary, the linkage device can be activated to ventilate or close the gas source to eliminate dangers and effectively avoid fire, explosion, poisoning and other vicious accidents caused by natural gas leakage.
The continuous emergence of black technology products in the fields of consumer electronics, medical health, human-computer interaction and other fields has brought flexible sensors into front of people. For example, many Bluetooth headsets have begun to abandon the traditional touch-sensitive mode and instead adopt the most advanced pressure-sensitive control mode. Users only need to lightly press or slide up and down on the headphone handle to easily switch modes, pause, and adjust the volume. To accomplish such an operation, flexible sensors must be used.
It is worth noting that the car sensors, laser gas sensors, household combustible gas alarms, and flexible sensors just mentioned all come from Hanwei Technology. Hanwei Technology is known as a leading gas sensor company, and from the multiple series of sensor products and solutions at its booth, we can find that in recent years Hanwei Technology has made efforts in the fields of cutting-edge sensor technologies such as automobiles, home appliances, and MEMS, lasers, and flexibility. Obviously, many products have reached the international leading level and are moving towards the leading comprehensive sensor company. During the Shanghai Sensor Exhibition, many visitors stopped to communicate and learn about related sensor products.
Sensors are the foundation of perception in the era of intelligence and the Internet of Things. With the increasing demand for various intelligent sensing in my country's 3C electronics, new energy vehicles and other fields, as well as the rapid development of downstream markets in the future, the size of the sensor market has grown significantly. According to the forecast of the Qianzhan Industry Research Institute, the compound annual growth rate of the sensor manufacturing industry will reach 19% in the next five years. It is expected that the market size of China's sensor industry will reach 708.2 billion yuan in 2026. The sensor industry has a very broad prospect.
At the same time, the development of the sensor industry has attracted more and more attention from the country. On July 14, 2023, the official website of the National Development and Reform Commission issued an announcement to publicly solicit opinions on the "Guidance Catalog for Industrial Structural Adjustment (2023 version, draft for comments)". The catalog consists of three categories: encouragement, restriction, and elimination. It is important for guiding my country's industries. development is of great significance. Among them, in the sensor industry, the encouraged category covers more than 20 types of sensor products in 10 industries. In the future, with the strong support of national policies, domestic sensor companies represented by Hanwei Technology will continue to help my country's sensor industry continue to develop in the direction of comprehensive localization, independent control, and lay the foundation for the intelligent transformation of my country's various industries. A solid digital base.
