Covered by Economic Daily | GalaxyX-Chip: Homegrown Sensor Chips Fuel Smart Home Industrial Upgrade

Recently, Economic Daily published an in-depth survey on the smart home industry, outlining the opportunities, pain points and development direction of the trillion-yuan smart home market, with GXCAS featured in this industry report.

The report notes that sensors serve as the perceptual nerve endings of smart homes. Temperature, humidity and air quality sensing are indispensable for home appliances; inaccurate sensor data will render upper-layer AI decisions and scene linkage invalid. Beijing GXCAS Technology Co., Ltd. is a high-tech enterprise specializing in high-end environmental sensor chip design, providing reliable, cost-effective "China Chips" for smart home applications.

Our newly developed generation of temperature and humidity sensors adopts CMOS+MEMS technology, integrating temperature and humidity measurement on a single silicon-based CMOS die. It delivers temperature accuracy up to ±0.2°C and humidity accuracy up to ±2% RH via an integrated high-sensitivity MEMS humidity-sensing element. At 16-bit resolution, its fastest temperature conversion rate reaches 2.5 ms. The chip features excellent precision, reliability, consistency and anti-interference performance. It supports applications such as anti-condensation control for refrigerators, drying judgment for dryers and comfort humidity adjustment for air conditioners, delivering stable and accurate environmental sensing signals. White goods require chips that can maintain stable performance for 5–10 years. We adopt full in-house R&D throughout the technical chain, with performance comparable to leading overseas solutions. Supported by local fast delivery and on-site technical service, our chips are continuously adopted by mainstream home appliance supply chains to advance the localization of core components.

The smart home industry is undergoing profound transformation: mandatory interconnection standards are being rolled out, and AI is shifting devices from passive response to active service. Lightweight retrofitting unlocks inclusive market potential. Meanwhile, industry fragmentation and shortages of high-end components remain major challenges calling for cross-industry collaboration. Reliable and precise sensing is the foundation for interconnection and AI in whole-home smart systems. Localization of sensor chips is critical for the high-quality development of China’s smart home sector.

This coverage by Economic Daily recognizes our long-term dedication to environmental sensor chips and independent innovation. Going forward, GXCAS will keep investing in sensor chip R&D, uphold indigenous innovation, and deliver robust domestic sensing chips for diversified IoT scenarios. We will work with industrial partners to drive high-quality growth of the smart home industry.
