About Shenzhen YYS Technology · Since 2012
A specialist sensor module
manufacturer — not a trader.
YYS designs, calibrates and produces air-quality, gas and temperature-humidity sensor modules in our Shenzhen facility. We support OEM equipment programs from sample evaluation through long-term bulk supply.
- National High-Tech Enterprise
- 12+ Years in Sensing
- OEM & ODM Ready
Company Profile
Focused on air quality, gas detection and environmental sensing.
YYS serves OEM equipment programs across IAQ monitors, appliances, fresh-air systems, instruments, industrial monitoring and environmental control. Our engineers cover NDIR, electrochemical, MOS, laser particulate and capacitive humidity in one facility — which is why we can ship single-purpose modules and multi-parameter modules from the same supplier.
Explore our sensing technologies →Capabilities
R&D, calibration and production under one roof.
In-house R&D
Analog front-end, firmware, calibration algorithms and protocol stack developed by our own engineering team — no black-box from upstream.
Calibration line
Each module is calibrated against reference instruments before shipment. Calibration curves and unit-level records traceable on request.
SMT & assembly
SMT, conformal coating, ageing and final QA all completed locally — short feedback loop when an OEM batch needs adjustment.
Long-term supply
Stable BOM, traceable batches, multi-year lifecycle commitments for OEM programs that ship across multiple production cycles.
Patents & copyrights
Multiple utility-model patents and software copyrights covering sensing-element design, calibration methodology and module integration.
Documentation discipline
Datasheets, test reports, RoHS / REACH declarations and SOP documents prepared per customer program, not on-the-fly.
Company Timeline
From sensing R&D to OEM-grade module supply.
Shenzhen YYS Technology founded.
