Applied sensing solutions
Smart home appliances
HMNST delivers high-quality, cost-effective gas sensor solutions for the appliance market, helping brands build safer and smarter user experiences. MEMS gas sensors accurately detect natural gas leaks, kitchen VOC, and indoor formaldehyde, and are widely integrated into smart gas alarms, range hoods, air purifiers, and fresh-air systems for real-time sensing and intelligent linkage control.
Safe driving
Building on MEMS gas sensing technology, HMNST provides accurate and reliable sensor solutions for automotive electronics — covering cabin air quality monitoring, new-energy battery safety early warning, and cockpit environmental sensing. Vehicle sensors detect harmful gases such as CO, TVOC, and hydrogen in real time, and issue early warnings before thermal runaway.
Consumer products
As IoT and smart hardware proliferate, consumers demand ever more accurate health and environmental awareness. HMNST uses ultra-low-power MEMS sensors to bring precise sensing into consumer electronics and wearables — covering smart watches, portable gas detectors, non-contact temperature devices, and more.
Industrial environmental protection
HMNST provides MEMS sensing systems and instruments for industrial environmental scenarios, helping customers fulfill commitments to environmental safety and occupational health — from utility tunnel gas monitoring and chemical plant protection to emission monitoring and hazardous chemical safety control.
