View DetailsBeijing Yingchuanglihe Electronic Technology Co., Ltd. (YCLI) is a premier manufacturer of environmental monitoring sensors, instrumentation, and centralized cloud telemetry software systems. Founded in 2007, we have dedicated over 18 years to engineering temperature, humidity, gas analysis, and barometric telemetry devices that serve as the backbone of modern IoT infrastructure.
Operating from our headquarters in Beijing's advanced high-tech corridor, we control a state-of-the-art production base exceeding 1,500 square meters. Our workforce of over 100 engineering, R&D, and manufacturing specialists works to guarantee that our products exceed international quality, reliability, and precision standards.
YCLI production facility features automated surface mount assembly lines and custom environmental calibration rooms.
Our commitment to rigorous testing, premium component sourcing, and international compliance guarantees system stability.
We source primary sensors directly from market-leading fabricators (such as Sensirion and Bosch), ensuring raw accuracy thresholds of ±0.2°C for temperature and ±1.5% RH for humidity with long-term stability.
Every APEM-5930 model undergoes extensive electromagnetic compatibility, RF emission, and hazardous substances validation, matching European and American regulatory import rules.
Native engineering integrations for TCP/IP, Modbus TCP, SNMP (v1, v2c, v3), MQTT, and custom API layers allow our sensors to drop directly into existing building management systems (BMS) and SCADA platforms.
The APEM-5930 series represents the pinnacle of modern micro-environmental monitoring. Utilizing an internal high-speed ARM Cortex-M4 processing unit, each transmitter samples dry-bulb temperature, absolute pressure, and relative capacitive humidity at millisecond intervals. Advanced firmware algorithms execute a physical dew-point conversion using the Arden Buck equations, yielding real-time outputs of dew-point values without requiring external processor calculations.
Unlike conventional serial sensors (RS485/Modbus RTU) which require localized master PLCs, the APEM-5930 operates natively on Ethernet backbones (RJ45 10/100 Mbps auto-negotiation). It implements an isolated Power over Ethernet (PoE) circuit compliant with the IEEE 802.3af standard, protecting internal instrumentation from transient electrical spikes and ground loops up to 1500V AC.
| Telemetry Parameter | Sensing Range | Accuracy (Raw Chipset Output) | Long-Term Annual Drift |
|---|---|---|---|
| Dry Bulb Temperature | -40°C to +85°C (Extended probe configs) | ±0.2°C (between 0°C and 60°C) | < 0.03°C / Year |
| Relative Humidity (RH) | 0% to 100% RH (Non-condensing) | ±1.5% RH (between 10% and 90% RH) | < 0.25% RH / Year |
| Atmospheric Pressure | 300 hPa to 1100 hPa | ±1.0 hPa | < 1.0 hPa / Year |
| Gas Detection (O₃, CO, SO₂, H₂S) | Configurable per model (ppm thresholds) | ±5% Full Scale | < 2% Full Scale / Year |
At Yingchuanglihe, we are constantly pushing the boundaries of environmental monitoring. Our 3-year technical roadmap is centered on three core pillars:
Translating raw telemetry parameters into enterprise security, compliance, and operating efficiency.
Continuous relative humidity monitoring within cold/hot aisle containment structures. The APEM-5930 prevents dry static discharges and high moisture condensation on critical blade server motherboards, following ASHRAE requirements.
Maintains pressure differential tracking alongside precise temperature and humidity logging. Essential for meeting GAMP 5 and FDA 21 CFR Part 11 requirements in sterile biological product processing.
Integrated pipeline and underground vault tracking. Built to withstand continuous high moisture conditions, providing consistent telemetry parameters to prevent critical corrosion points in utility lines.
Yingchuanglihe leverages the advanced electronic supply chains of Beijing and the surrounding regions. Our production plant features SMT (Surface Mount Technology) assembly lines and computerized calibration equipment, drastically minimizing human assembly variations.
Every sensor goes through a multi-point testing loop inside closed environmental chambers, cross-referencing our hardware outputs against certified secondary reference meters. This ensures our inventory remains calibration-stable before shipping to overseas distributors.
Our established inventory networks protect clients from raw materials constraints, guaranteeing consistent lead times on orders ranging from low-volume custom batches to thousands of telemetry endpoints.
