Explore DetailFounded in 2007, Beijing Yingchuanglihe Electronic Technology Co., Ltd. (YCLISENSORS) stands as a prominent Chinese high-tech manufacturer specializing in industrial environmental monitoring instruments. Over nearly two decades, we have engineered and produced a full range of high-precision temperature, humidity, dew point, atmospheric pressure, and multi-gas sensor solutions. Operating from our advanced 1,500 square meter facility in Beijing and supported by five automated production lines, our team of over 100 specialists coordinates in-house R&D, manufacturing, strict calibration, and global sales.
Our mission is to deliver dependable environmental data to support intelligent municipal projects, high-density data centers, cold chain networks, and industrial cleanrooms. By integrating premium Swiss and German sensing chips with robust communication protocols, we ensure long-term stability and compliance with CE, FCC, and RoHS directives.
"Every high-precision temperature and humidity transmitter we produce utilizes imported sensor modules from Switzerland (Sensirion SHT series) and Germany, ensuring a low annual drift rate (<0.04°C/year and <0.5% RH/year) for mission-critical deployments."
High precision requires premium raw components. At YCLISENSORS, we source sensor chips from Switzerland and Germany. These elements are coupled with high-performance STM32 microcontrollers to deliver rapid response times, low power consumption, and reliable Analog-to-Digital conversion.
Our industrial transmitters feature physical thermal isolation designs that decouple heat-generating microprocessors and Power-over-Ethernet (PoE) modules from the active sensor probes. This structure prevents internal heat dissipation from altering ambient measurements, preserving the accuracy of temperature readings down to ±0.2°C and humidity to ±1.5% RH.
Simplifies installations by transmitting both operational power and environmental data over a single standard Cat5e/Cat6 cable.
Supports Modbus TCP/RTU, SNMP (v1/v2c/v3), MQTT, and HTTP GET/POST, enabling compatibility with SCADA, BMS, and DCIM systems.
Monitors temperature and humidity alongside atmospheric pressure, TVOC, formaldehyde (HCHO), ozone (O3), carbon monoxide (CO), hydrogen sulfide (H2S), and oxygen (O2).
China's manufacturing sector offers distinct advantages that enable YCLISENSORS to supply high-precision instruments at competitive price-to-performance ratios:
Comprehensive Supply Chain Ecosystem: Our close proximity to leading component suppliers, enclosure mold builders, and high-quality PCB assembly houses enables rapid turnarounds from initial layout to finished product.
Advanced Testing Infrastructure: Our Beijing plant utilizes multi-point temperature and humidity calibration chambers, reference chilled-mirror hygrometers, and gas calibration setups. This testing infrastructure ensures each transmitter leaves the factory pre-calibrated to national metrology standards.
OEM/ODM Versatility: We support custom development, including modified firmware registers, bespoke enclosure colors, and custom cabling lengths, accommodating requirements that are often cost-prohibitive for Western manufacturers.
Our development trajectory reflects our focus on industrial demands and technological evolution:
Established the company in Beijing. Developed our first intelligent environmental monitoring terminal based on native TCP/IP network protocol alongside our initial environmental monitoring software package.
Partnered with Mocha Software to design the TH-5939 series, featuring integrated SNMP support for IT network management systems.
Partnered with COMLAB (Switzerland) to engineer the TH-5869 ruggedized protective Ethernet environmental device, deployed on high-speed rail lines including the Beijing-Kowloon and Wuhan-Guangzhou routes.
Collaborated with Founder Technology to launch the APEM-6100, one of the earliest environmental monitoring transmitters to incorporate Power-over-Ethernet (PoE).
Collaborated with Foxconn, establishing our sensors as reference designs for cleanrooms and high-tech manufacturing workshops.
Partnered with Baidu to deploy the APEM-5900 intelligent environmental terminal at Baidu's Yangquan Data Center. Upgraded software platforms to support complex multi-parameter monitoring.
Expanded our product portfolio with smart data center monitoring architectures and introduced outdoor cabinet systems for Huawei and China Merchants Huaruan ETC road networks.
Contributed to Beijing's high-level autonomous driving road tests by designing environmental sensors for integrated roadside equipment boxes and edge computing gateways.
Developed solutions for AI intelligent computing centers. Formed joint divisions with Beijing Enterprises Water Group and Beijing University of Civil Engineering and Architecture for Beidou-powered deformation tracking. Obtained official IDC business qualifications.
High-precision sensors are critical component interfaces that supply clean datasets to industrial control and automated management layers.
Integrates with DCIM frameworks via SNMP or Modbus TCP to track intake temperatures, helping optimize CRAC cooling and Power Usage Effectiveness (PUE).
Monitors temperature, relative humidity, and barometric pressure differentials to prevent cross-contamination and support compliance with GMP/GLP standards.
Supplies ruggedized IP65/IP67 rated housings and customized cable probes that monitor temperature and moisture levels in outdoor highway cabinets and roadside computing enclosures.
We maintain rigorous calibration and quality control standards. Each product undergoes multi-point testing in environmental chambers before shipping.
Common technical questions regarding our industrial sensor arrays:
Our transmitters utilize Sensirion SHT series digital sensor ICs. Standard models maintain temperature accuracy of ±0.2°C and humidity accuracy of ±1.5% to ±2% RH. The annual drift rate is less than 0.04°C and 0.5% RH in typical operating environments, minimizing the need for frequent recalibration.
The APEM-5930 supports IEEE 802.3af standard Power-over-Ethernet, allowing it to draw power directly from PoE network switches via standard RJ45 Ethernet ports. It also supports auxiliary DC power input (12V-48V) for backup power configurations.
Our sensors support Modbus TCP for PLCs, SNMP (v1, v2c, and v3) for IT monitoring platforms, MQTT for cloud-based IoT networks, and HTTP GET/POST for custom web applications. The integrated RS485 port also enables Modbus RTU connectivity.
The sensor probe is physically isolated from the main processor and network transceiver modules. For applications demanding high thermal isolation, we offer models with extended cable probes (up to 3 meters), separating the active measuring element from the electronics.
Yes, the APEM-5930G series integrates electrochemical and metal-oxide gas sensors to monitor TVOC, Formaldehyde (HCHO), O3, CO, O2, H2S, SO2, and NO2 within a single device, consolidating your hardware footprint.
For standard models, we maintain inventory components that allow shipping within 5-10 business days. Custom OEM/ODM orders requiring hardware modifications or custom firmware development typically require 3-6 weeks, depending on design complexity.
Yes, our entire environmental sensor family carries CE certification, FCC compliance approvals, and RoHS alignment, ensuring compatibility with regulatory frameworks in Europe, North America, and Asia.
