Explore our top-tier CE-certified environmental monitoring sensors engineered for high reliability in remote industrial, outdoor, and smart-building architectures.
Designing electronic equipment destined for decades-long outdoor exposures presents severe challenges. Outdoor humidity sensors operate in dynamic and violent temperature oscillations, relative humidity (RH) saturation phases, UV radiation, and severe electromagnetic interference (EMI). CE Certification is not merely an administrative credential; it represents an intensive manufacturing commitment to electrical safety, low electromagnetic radiation profiles, and resilient resistance to ambient environmental noise.
By complying strictly with European Standards (EN IEC 61000 and dynamic EMC testing procedures), our CE-marked transmitters utilize cutting-edge protective architectures. These safeguard sensitive microchip controllers against massive grid fluctuations, atmospheric static discharges, and transient industrial currents common in factory setups, substation monitors, and telecommunication cell towers.
To assure persistent calibration linearity and prevent sensor drift over long cycles, our outdoor telemetry stations incorporate automated moisture purging and micro-heating element routines. This ensures that even when relative atmospheric humidity approaches 100% condensation, the active capacitive polymer element dries efficiently, resuming accurate monitoring in minutes without permanent drift.
To deliver uncompromising instrumentation-grade precision, we partner with Swiss and German semiconductor innovators. By integrating world-class MEMS-based polymer capacitive humidity chips directly into our transmitters, we assure:
This premium silicon core is augmented with integrated dual analog-to-digital converters (ADC) and high-density EEPROM, storing unique calibration curves on-chip for absolute sensor exchangeability without field recalibration.

Access advanced manufacturing, precise calibration, and robust testing at scale.
Located in Beijing's advanced industrial district, our state-of-the-art facility features a 1,500m² manufacturing footprint housing five automated SMT lines, automated sensor calibration equipment, and environmental test chambers. By operating entirely in-house, we eliminate quality bottlenecks and maintain direct oversight of every component from the raw PCB assembly to final IP-rated sensor encapsulation.
Every single outdoor sensor manufactured in our Beijing facility passes through automated multi-point thermal and humidity calibration tunnels. We generate unique calibration certificates traceably linked to international standards. This precise calibration assures that when our sensors arrive at your remote field location, their drift profiles remain flat and they deliver stable telemetry from day one.

Our dedicated R&D engineering department responds to customer inquiries within 8 hours, delivering fully optimized custom PCB layouts, personalized 3D-printed housing prototypes, and firmware alterations to ensure seamless hardware integration.
Beijing Yingchuanglihe Electronic Technology Co., Ltd. has stood at the forefront of the environmental monitoring sector for nearly two decades. Founded with a vision to deliver robust, industrial-grade data interfaces, we have consistently evolved alongside the internet of things (IoT) revolution.
From early-generation protective Ethernet transmitters deployed in the high-speed rail lines of China to high-density smart data centers with Baidu, our products serve as the sensory nervous system for mission-critical digital infrastructures.
Today, with a robust network of domestic and international industry partners, we continue to engineer new standards in multi-gas integration, wireless LoRaWAN technology, and autonomous high-accuracy environmental telemetry systems.
Our operational scale demonstrates why international engineering firms specify our telemetry probes in their master designs.
How our multi-parameter transmitters deliver high performance across diverse mission-critical application domains.
Sudden changes in relative atmospheric humidity can trigger dense regional fog, creating extreme road hazards on modern high-speed transportation corridors. By pairing our APEM-5930P Ethernet atmospheric pressure and humidity sensors within roadside telemetry hubs, regional traffic operators can calculate atmospheric dew points instantly. This enables them to trigger automated dynamic digital signage warning drivers of sudden microclimatic changes.
Modern high-density data infrastructures require strict micro-climate regulation to prevent static electricity discharges from low moisture states, or galvanic corrosion from high relative humidity. Deploying our Power over Ethernet (PoE) APEM-5930 sensors throughout cooling aisles provides infrastructure servers with granular real-time environmental data. This optimizes active cooling output, lowering overall facility energy consumption (PUE).
Underground water infrastructures and remote oil/gas valve chambers are prone to severe condensation and hazardous gas accumulation. By deploying our custom APEM-5930G multi-gas telemetry nodes (sensing Oxygen, Hydrogen Sulfide, and Dew-point), engineering departments can monitor hazardous confined space conditions. This helps protect repair crews, preventing catastrophic pipeline corrosion through proactive maintenance cycles.

Outdoor humidity sensors are prone to progressive drift caused by volatile organic compound (VOC) exposure, chemical outgassing, and prolonged moisture saturation. Our CE-certified outdoor transmitters prevent drift by utilizing high-precision polymer capacitive elements featuring active temperature-drift compensation. By utilizing hydrophobic membrane filters, the internal sensing element remains protected from dust and liquid water, keeping annual drift under 0.25% RH.
CE Certification is vital for ensuring high-performance electrical safety and electromagnetic compatibility (EMC). In outdoor industrial environments, transient power spikes and heavy machinery noise can disrupt sensor telemetry. Our CE-certified transmitters are fully tested to survive static discharge and magnetic fields without losing connection or delivering corrupted data packet arrays.
By utilizing standard IEEE 802.3 PoE, a single RJ45 cable transmits both reliable low-voltage power and high-speed bidirectional telemetry. This removes the need for expensive high-voltage electrical routing to remote sensor boxes. Additionally, it minimizes thermal heating within the sensor box, ensuring accurate ambient measurements without internal heat contamination.
