Explore our highly integrated APEM network sensors, custom-built for server rooms, smart buildings, laboratories, and cleanroom networks.
The critical transition from legacy serial logs to real-time, PoE-enabled environmental architectures.
In modern industrial automation, data center facilities management, and pharmaceutical storage sectors, environmental control is no longer a matter of periodic manual logs. Legacies systems relied heavily on RS-485 Modbus RTU loops or unreliable consumer-grade Wi-Fi routers. These networks often introduced communication lag, vulnerability to EMF noise, and required complex secondary power cabling architectures.
As a leading Custom Ethernet Thermo-Hygrometer Data Logger Manufacturer, Beijing Yingchuanglihe has pioneered the deployment of Power over Ethernet (PoE) 802.3af/at standard telemetry units. The modern industrial factory floor, deep cleanroom, or edge compute gateway demands direct-to-cloud/on-premise networking protocols, high resolution Swiss-imported humidity sensors, and multi-gas array compatibility within a single physical hub. By deploying Modbus TCP, SNMP, and MQTT over structured CAT6 cabling, enterprise operators bypass the need for power adapters at each drop while securing a stable, hack-resistant telemetry system aligned with strict corporate IT security protocols.
Industrial excellence in environmental sensor technology since 2007.
Beijing Yingchuanglihe Electronic Technology Co., Ltd. is a high-tech environmental monitoring manufacturer integrating dynamic R&D, sophisticated ISO9001-certified manufacturing, and global commercial sales. For nearly two decades, we have provided comprehensive atmospheric, temperature, humidity, and multi-parameter air quality arrays to global enterprise infrastructures. Operating a modern 1,500+ m² facility in Beijing housing five high-throughput automated production lines, our team of engineers maintains close joint labs and development projects with top-tier firms like Foxconn, Baidu, and Mocha Software.
Our engineering methodology balances absolute measurement accuracy with high networking flexibility. Every Ethernet thermo-hygrometer leaving our line undergoes multi-point calibration in custom micro-chambers, referencing traceable chilled-mirror dew point hygrometers. We deploy high-grade imported chips from Switzerland and Germany, ensuring that our systems exhibit minimum drift (<0.1°C / <1.5%RH annually), guaranteeing stable long-term operations inside intelligent data center hot aisles or sterile pharmaceutical cleanrooms.

Providing mission-critical environmental intelligence to diverse commercial and infrastructural systems.
Ethernet environmental logging plays a key role in the optimization of modern industrial plants. Rather than acting as standalone gauges, our monitors serve as critical nodes in broader network control setups. Below is how our global clients deploy Yingchuanglihe technology across specialized fields:
To achieve optimal Power Usage Effectiveness (PUE) without risking thermal runaways, server room racks require continuous micro-climate monitoring. Using the APEM-5930, operators place multi-point nodes at the hot-aisle containment zones and cold-aisle supply lines, reporting live data via SNMP to DCIM systems (e.g., Baidu Yangquan Data Center) for automated fan and chiller adjustments.
Regulated facilities must strictly comply with FDA 21 CFR Part 11 and GAMP 5 data validation guidelines. By integrating our APEM-5930P (incorporating high-resolution differential barometric pressure sensors) cleanroom engineers ensure that positive pressure levels prevent cross-contamination while logging temp/RH values directly to a secure, audit-ready Modbus TCP database.
Modern smart highways utilize outdoor Cabinet Control units containing edge servers. In projects such as Huawei's ETC highway systems, our ruggedized outdoor monitor chassis protect delicate electronics by dynamically reporting water-ingress (via secondary leakage ropes), overheating, and dew point condensation risks to centralized road management stations.
Preserving valuable perishables, historic artifacts in archives, or electronics raw materials demands precise, uninterrupted environmental monitoring. Our multi-probe sensor gateways allow remote placement of active probes inside deep storage lockers while keeping the network processing unit outside the cold zone for reliable operation and easy maintenance.

Detailed documentation addressing common questions from global engineering, procurement, and IT operations teams.
We exclusively integrate premium imported sensor elements. Typically, Switzerland Sensirion CMOSens technology cores are used for temperature, humidity, and dew point measurements, while Germany Bosch components are used for barometric pressure calculations. This ensures exceptional precision and low calibration drift over long term operations.
Our firmware natively supports standard industry communication protocols, including Modbus TCP/IP, SNMP (v1/v2c/v3), MQTT, JSON over HTTP, and traditional RS-485 Modbus RTU pass-through. This allows seamless integration into systems like Zabbix, PRTG, Ignition SCADA, Baidu Cloud IoT, and custom BMS frameworks.
Yes. APEM-5930, APEM-5930E, APEM-5930P, and the APEM-5930G range support the IEEE 802.3af PoE standard. Power and data transmission share a single CAT5e/CAT6 network line. We also provide DC 12V-48V auxiliary power inputs as redundant back-ups for setups requiring continuous uptime.
The APEM-5930E isolates the main network controller from the active sensor element via a durable 1 to 3-meter cable. This setup is ideal for measuring inside incubation chambers, refrigeration units, HVAC ducts, or vacuum environments where high temperatures, vibration, or metal shields would degrade standard wireless signals or damage the main processing unit.
The APEM-5930G supports interchangeable, pre-calibrated sensor boards for TVOC, HCHO, CO, O₃, SO₂, and NO₂. Each channel features automatic zero-point drift compensation algorithms. When a chemical sensor element reaches the end of its life, operators can swap the internal cartridge without having to replace or rewire the main Ethernet network transmitter box.
We provide comprehensive custom engineering services. This includes private-label enclosure designs, custom cable lengths for external probes, custom communication interfaces, alternative firmware with unique protocol requirements, custom measurement ranges, and pre-configured IP network parameters tailored for mass site roll-outs.
