Industry-proven wired and wireless sensors designed for remote ambient diagnostics, micro-climate stabilization, and equipment protection.
Modern compute infrastructure operates under extreme performance thresholds. High-density server deployments, GPU clusters for artificial intelligence (AI), and hyperscale cloud processing generate massive thermal output that challenges traditional cooling systems. Uncontrolled ambient parameters lead to catastrophic consequences: thermal runaway, localized hotspots, dry air static discharges, and corrosive condensation. Data Center Environmental Monitoring Tools (DCEMTs) provide the essential telemetry required to maintain continuous equipment availability.
As global power usage effectiveness (PUE) requirements become increasingly strict under modern environmental regulations, data centers must shift from static cooling regimes to dynamic, sensor-driven HVAC control. Monitoring systems must capture high-resolution temperature and relative humidity data, and also analyze barometric differential pressures, gaseous contaminant thresholds, volatile organic compounds (VOCs), and liquid leaks. By deploying multi-parameter sensor arrays at key cabinet intake zones and hot aisles, engineers can execute real-time ASHRAE TC 9.9 thermal management strategies.

At the core of the APEM series design is high reliability. Standard commercial-grade sensors often drift over time when exposed to the high wind velocities and dry conditions of data center aisles. Our instruments utilize internal micro-heating elements that prevent moisture buildup during high humidity states, reducing drift to less than 0.1°C per year.
The hardware integration leverages high-reliability circuitry designed to protect against electromagnetic interference (EMI) generated by surrounding high-density server power supplies. Dual-power redundancy is standard: devices operate on 12-48V DC auxiliary power alongside standard Power over Ethernet (PoE 802.3af), ensuring that environmental telemetry continues even during power phase changes or network switch maintenance.
Eliminate complex power infrastructure layouts at the rack level. Yingchuanglihe's APEM-5930 utilizes a single RJ45 Cat5e/Cat6 cable to carry both operational power and telemetry data. This design minimizes cabling bulk, reduces installation points of failure, and allows centralized power backup via UPS-supported network switch ports.
For larger physical layouts where ethernet deployment is not cost-effective, the APEM-5736 series utilizes LoRaWAN wireless technology. Operating across regional sub-GHz bands, these sensors penetrate metal server cages and concrete partitions, reporting stable telemetry over hundreds of meters without interfering with existing Wi-Fi networks.
Data center components can degrade when exposed to corrosive airborne chemicals. Our multi-parameter gas monitors (APEM-5930G series) track TVOC, Ozone (O₃), Carbon Monoxide (CO), Sulfur Dioxide (SO₂), Nitrogen Dioxide (NO₂), and Hydrogen Sulfide (H₂S) levels, protecting PCB copper traces against silver migration and galvanic corrosion.

We actively showcase our latest sensor innovations at global electronic, computing, and smart infrastructure expos. By engaging directly with system integrators and site managers, we continue to refine our technical designs to meet real-world operational challenges.
The rapid expansion of artificial intelligence (AI) computing centers, characterized by dense GPU server clusters, is changing thermal management in data centers. Standard rack power densities are shifting from 5kW–10kW up to 40kW–100kW per cabinet. At these high densities, traditional air cooling is often replaced by liquid cooling systems, such as rear-door heat exchangers or direct-to-chip liquid loops.
In liquid-cooled environments, micro-leak detection and local relative humidity monitoring are critical. The presence of water or coolant near high-voltage lines can cause short circuits and equipment damage. Yingchuanglihe is addressing these changes by developing integrated liquid leak detection cables and spot sensors that link with our PoE and LoRaWAN gateways. This ensures early warning capabilities for hybrid-cooled and fully liquid-cooled compute halls.
We are also integrating Beidou high-precision satellite positioning modules into our outdoor monitoring arrays. For large infrastructure projects, such as pipeline networks and data centers in geologically active regions, monitoring structural shift and physical deformation is just as important as tracking thermal metrics. Integrating environmental telemetry with spatial deformation analysis allows operators to manage both data security and physical building integrity under a single dashboard.
