Real-time thermodynamic calculation of dew point temperatures based on the Arden Buck equation. Prevents active condensation hazards on critical high-voltage assets, structural server enclosures, and manufacturing equipment pipelines.
By employing direct-wafer bonding capacitive humidity sensors coupled with band-gap temperature sensors, our modules boast exceptional recovery profiles from saturated moisture states, maintaining dynamic precision.
To resist volatile organic chemical contamination, dust ingress, and acid gas interference, we offer stainless steel sintered metal, porous PTFE, and copper dust caps that safeguard internal sensing substrates.
Beijing Yingchuanglihe Electronic Technology Co., Ltd. is a premier, high-tech industrial environmental monitoring enterprise. Established in 2007, we operate a cutting-edge 1,500+ square meter manufacturing facility in Beijing with over 100 dedicated technical staff. Over the past 18 years, our engineering team has integrated state-of-the-art sensor arrays, developing embedded electronics that power intelligent automated monitoring frameworks globally.
Our research and development division handles intensive digital signal processing, multi-hop mesh networking protocols (like LoRaWAN), high-efficiency Ethernet Power Delivery (PoE), and custom sensor micro-calibration. By sourcing the finest raw sensor chips from market leaders in Germany and Switzerland, we ensure that every unit rolling off our five automated calibration pipelines delivers highly repeatable results across complex thermal shifts.
Every single device under our brand is fully compliant with CE, FCC, and RoHS international standards, ensuring seamless integration into foreign automation panels and structural telecom architectures.
Our journey is characterized by continuous technical innovations, system integrations, and collaborative joint ventures with global enterprise leaders. Here is how Yingchuanglihe became an industry benchmark:

Sourcing your industrial-grade sensors from our Beijing facility provides unique technological and commercial benefits. Unlike typical distributors or simple assembly houses, Yingchuanglihe's complete supply vertical ensures that custom product revisions move from design to final execution seamlessly.
We operate micro-climate chambers capable of precise calibration over dynamic humidity sweeps (10% to 95% RH) and extensive thermal profiles (-40°C to +85°C). Utilizing multi-point dynamic fitting algorithms, we program correction registers in each sensor's firmware to guarantee optimal accuracy.
Our location in Beijing's technology manufacturing cluster allows us to secure raw semiconductor components, premium sub-assemblies, and specialized micro-machined parts rapidly. This enables us to maintain shorter lead times and adapt easily to changing component specifications.
Whether you require a custom plastic housing color, localized Ethernet connector configurations (RJ45, M12), specialized firmware registers (Modbus map customization), or additional atmospheric sensors, our design team can prototype, test, and deliver specialized batches within weeks.
Modern operations require more than simple temperature and humidity readouts. They require robust industrial endpoints that integrate seamlessly with advanced networking protocols and building automation systems.
High-density AI server structures demand responsive environmental controls to prevent moisture buildup and electrostatic hazards. Our POE APEM series provides rapid dew point calculation, allowing chillers and cooling loops to dynamically adjust before dew point condensation occurs. Trusted across massive multi-megawatt hyperscale campuses like Baidu's Yangquan site.
Maintaining precise environmental parameters is essential for pharmaceutical formulation and semiconductor lithography. Our high-precision custom sensors provide ±1.5% RH accuracy, while supporting additional cleanroom parameters like atmospheric pressure differentials and TVOC/ozone levels, all monitored over a centralized Ethernet interface.
Highway monitoring units, edge computing cabinets, and cellular base stations are exposed to harsh weather conditions. Our custom external probe options (like the APEM-5930E) feature robust enclosures with IP-rated protection, allowing the sensitive core electronics to be safely contained within insulated housings.
From automated vertical farms to refrigerated cargo holds, maintaining stable microclimates is critical for preserving quality. Using our low-power LoRaWAN or robust Wi-Fi capabilities, global agricultural facilities can deploy distributed sensor arrays that send real-time data back to automated control centers.
Providing clear, detailed answers to technical questions helps procurement managers and engineers select the optimal equipment for their applications.
Humidity sensor drift is typically caused by chemical contamination, particulate accumulation, or exposure to prolonged high humidity. Our APEM series addresses this by using premium Swiss and German MEMS sensing elements with protective hydrophobic membranes. For harsh industrial environments, we also offer sintered stainless steel filters and chemical mitigation coatings to shield the sensor core.
Yes, our environmental sensors calculate dew point dynamically using internal calculation routines. This dew point value is available directly over Modbus registers, SNMP outputs, and raw TCP packets, eliminating the need for post-processing calculations on host systems.
PoE (Power over Ethernet) combines power delivery and high-speed data transmission over a single standard RJ45 cable. This significantly reduces installation costs by eliminating the need for separate power runs, simplifies cable management, and allows for clean, centralized backup power delivery from PoE-enabled network switches.
For clients requiring specialized integration, our engineering team can custom-program the internal microcontroller firmware to match your existing register maps, SNMP MIB files, or proprietary communication protocols, ensuring smooth integration with legacy software platforms.
Our entire manufacturing process and custom product catalog comply with major international certifications, including CE, FCC, and RoHS, making them suitable for use in demanding markets across North America, Europe, and Asia.
