Established in 2007, Beijing Yingchuanglihe Electronic Technology Co., Ltd. stands as a premier high-tech enterprise dedicated to the R&D, production, and worldwide sales of high-precision environmental sensors and multi-parameter transmitters. Operating from our state-of-the-art 1,500m² manufacturing facility in Beijing, we empower modern infrastructure with robust, real-time data collection pipelines.
Our sensor systems rely on top-tier components imported from market leaders in Germany and Switzerland, delivering unmatched temporal stability and drift resistance under stressful industrial conditions.
An authoritative breakdown of industrial transmission protocols, sensor technologies, and edge deployments.
Modern industrial sites face diverse hardware environments, necessitating dual support for RS485 serial communication and Ethernet TCP/IP network interfaces. Modbus RTU over RS485 remains the bedrock for legacy SCADA systems and programmable logic controllers (PLCs) due to its high noise immunity over long distances (up to 1200 meters) and daisy-chain capability.
Conversely, our Ethernet-enabled data loggers support Modbus TCP, SNMP (v1/v2c/v3), and MQTT protocols. This allows direct connection to enterprise local area networks (LANs) and cloud IoT hubs. For critical environments, we integrate Power over Ethernet (PoE - IEEE 802.3af), enabling power and data to flow over a single Cat5e/Cat6 cable, minimizing structural cabling expenses and point-of-failure risks.
To assure compliance with stringent regulatory frameworks, our data loggers employ advanced MEMS capacitive relative humidity and bandgap temperature sensors imported directly from Switzerland and Germany. These chips feature on-chip calibration, digital processing, and long-term stability with minimal drift (typically <0.03°C and <0.25% RH per year).
During the manufacturing cycle, every device undergoes a strict multi-point temperature and humidity calibration protocol in our professional environmental chambers. This ensures NIST-traceability and direct correlation with reference standards. For multi-parameter units, auxiliary gas sensors (O₂, H₂S, SO₂, TVOC, CO) utilize temperature-compensated electrochemical cells for accurate gas concentration mapping.
Yingchuanglihe environmental sensors are deployed across diverse sectors, including:
Based in Beijing, our factory utilizes advanced automation across five distinct production lines. This setup enables rapid prototyping and short lead times. By centralizing assembly, calibration, QC inspection, and global shipment consolidation in Beijing, we shield customers from supply chain shocks.
Our strategic partnerships with premium component providers guarantee constant inventory availability of raw silicon, microcontrollers, and precision sensors. This vertical integration allows us to offer custom enclosure designs, private labeling, and custom firmware revisions with short development cycles.

Critical engineering insights for procurement officers and system integration specialists.
Select RS485 Modbus RTU if you are daisy-chaining multiple sensors to an existing PLC or industrial control loop up to 1200 meters. Select Ethernet (Modbus TCP/SNMP/MQTT) when you want to leverage existing office/facility network cabling, require Power over Ethernet (PoE), or need direct data ingestion into standard databases, cloud platforms, or IT monitoring packages.
Yes. The APEM-5930G series is designed for multi-parameter logging, enabling simultaneous tracking of Oxygen (O₂), Hydrogen Sulfide (H₂S), Sulfur Dioxide (SO₂), Nitrogen Dioxide (NO₂), Carbon Monoxide (CO), TVOCs, Ozone (O₃), and Formaldehyde (HCHO), in addition to ambient temperature and relative humidity.
For standard temperature and relative humidity measurements, we recommend calibration checks every 12 to 24 months depending on dust exposure. Electrochemical gas sensors generally require recalibration or replacement every 2 to 3 years to account for normal chemical cell depletion.
