The new MEMS pressure and micro-differential pressure sensors constitute one of the most cutting-edge and crucial sub-sectors within the pressure sensor domain. Duwei's intelligent research team has successfully tackled the technical challenges associated with micro-pressure sensors, overcoming the technical bottlenecks caused by temperature-induced zero drift and high-precision resolution issues, and redefining a novel micro-differential pressure sensor structure. Leveraging this technological principle, we have broken through the critical technology bottleneck that has previously blocked China's access to high-end sensor chip technology. This innovation finds extensive applications in the fields of semiconductors, chip manufacturing, industry, healthcare, aviation, automotive, and consumer electronics.

Although the current three-constant and five-constant systems have significant advantages in terms of comfort and health, they still have obvious shortcomings, such as high initial cost, stringent requirements for building insulation and construction precision, slow response speed to temperature and humidity, limited usage behavior, technical contradictions between dehumidification and fresh air, complex and costly maintenance in the later stages, and low system fault tolerance. Coupled with the proliferation of industry concepts, a large number of products are merely equipment assemblies rather than genuine system integration, leading to inconsistent actual experiences. These issues collectively restrict the large-scale popularization of three-constant and five-constant systems from high-end mansions to the general residential market. Dewei's "AI Environmental Conditioner" is the core product of Dewei in the field of smart home. Relying on self-developed intelligent sensors and large model AI algorithms, it organically integrates air conditioning and fresh air systems to create a new generation of AI air conditioning technology. Based on the industry standard for human comfort, the "AI Environmental Conditioner" product senses indoor and outdoor environmental data and human physiological indicators in real time through intelligent sensors. With the help of AI algorithms, it autonomously makes decisions and drives the automatic operation of the environmental control system. It can precisely control indoor air pressure and airflow direction, intelligently adjust temperature and humidity, increase oxygen content in enclosed spaces, effectively reduce the occurrence of respiratory diseases, improve sleep quality, and bring users a healthier and more comfortable indoor living experience.
