Beijing Yingchuanglihe Electronic Technology Co., Ltd. is a leading global developer and professional manufacturer of advanced environmental monitoring sensors. Since our establishment in 2007, we have dedicated ourselves to engineering high-precision temperature, humidity, atmospheric pressure, and multi-parameter air quality sensors. By providing accurate, real-time, and auditable data, we empower data centers, smart pharmaceutical warehouses, cleanrooms, and automated factories worldwide.
Headquartered in Beijing, China, our advanced facility spans over 1,500 square meters of high-tech production area. Utilizing automated manufacturing systems and strict quality controls, our team of more than 100 skilled specialists delivers OEM/ODM environmental monitoring hardware that seamlessly integrates into modern BMS (Building Management Systems) and industrial SCADA networks.
Industrial telemetry and environmental data acquisition systems are undergoing a rapid evolution. The demand for sub-degree accuracy, edge compute intelligence, and robust networking has pushed standard data loggers out of favor. Beijing Yingchuanglihe stands at the forefront of this technical transition. By integrating Swiss and German solid-state sensing elements with dual-core ARM microcontrollers, our Ethernet Temperature and Humidity Data Loggers deliver unparalleled long-term stability and network reliability.
Our APEM series relies on high-grade CMOSens® technology. These chips integrate the sensor elements and signal processing on a single silicon chip, preventing analog signal attenuation. By shielding the capacitive relative humidity sensor and the band-gap temperature sensor with customized PTFE membrane filters, our devices actively resist chemical vapors, dust accumulation, and condensation.

The next step in our technological roadmap is the deployment of localized anomaly detection and automatic calibration drift correction. Utilizing historical data streams, upcoming APEM models will execute onboard machine learning algorithms to predict sensor element degradation. If a drift in standard calibration is detected, the device will flag the maintenance interface while dynamically shifting the compensation curve to maintain strict compliance with global quality metrics.
In modern hyperscale data centers, thermal management is key to minimizing PUE (Power Usage Effectiveness). APEM-5930 series sensors provide real-time Modbus TCP and SNMP data streams directly to DCIM tools. Placed at the cold aisle inlet and hot aisle exhaust, they monitor thermal stratification and dew point levels to avoid electrostatic discharge and microscopic condensation damage.
Under strict FDA 21 CFR Part 11 and EU GMP Annex 11 guidelines, electronic data records for pharmaceuticals must be tamper-proof. APEM data loggers support encrypted network streams and internal non-volatile memory backup. Even if a network drop occurs, data is logged locally and backfilled automatically once connectivity is restored, ensuring zero data loss.
Maintaining strict temperature controls is vital for biological storage, fresh food chains, and sensitive chemical goods. Our Power over Ethernet (PoE) loggers eliminate the need for AC outlet installations at high storage racks. Standard Ethernet cables carry both power and signals up to 100 meters, dramatically reducing installation costs.
Based in Beijing's electronic technology industrial hub, Yingchuanglihe leverages the full power of China's advanced component ecosystem. We optimize our assembly lines with precision robotics, automated SMT (Surface Mount Technology) component placement, and dynamic environment simulation chambers. This integration of technology and logistics ensures high volume throughput while maintaining strict quality metrics.
At Yingchuanglihe, we do not compromise on the core measurement component. We purchase digital sensor chips directly from global leaders like Sensirion in Switzerland and Bosch in Germany. These chips undergo meticulous calibration in our automated chambers before integration, guaranteeing long-term drift-free operations.
For special system integration projects, standard enclosures do not always suffice. We operate an agile in-house design and prototyping team. Whether you require custom mounting brackets, IP-rated waterproof glands, external high-temperature probes, or custom branding, our engineers can supply fully functioning physical prototypes within 10 to 15 business days.
Every single Ethernet Temperature and Humidity Logger leaves our workshop only after passing a 3-step quality control regime:

Fully certified with CE, FCC, and RoHS standards. Our sensors meet strict global criteria for radio frequency interference, safety, and eco-friendly composition.
The company was founded and developed an intelligent environmental monitoring terminal based on the TCP/IP network protocol. In the same year, the initial version of environmental monitoring software was developed.
In collaboration with Mocha Software, a leading domestic network management software company, a series of SNMP protocol-supported environmental monitoring products, TH-5939, were launched.
In partnership with Switzerland's COMLAB, the TH-5869 protective Ethernet environmental monitoring device was introduced, successfully applied in high-speed rail projects such as the Beijing-Kowloon Line, Beijing-Shanghai Line, and Wuhan-Guangzhou Line.
Cooperating with Founder Technology, the APEM-6100 Ethernet environmental monitoring device was launched. This product was among the early environmental monitoring devices to adopt Power over Ethernet (PoE) technology.
Collaboration with Taiwan's Foxconn, combined with the influence of clients in the industry, established the company's products as one of the industry standards for environmental monitoring in production workshops.
In partnership with Baidu, the next-generation APEM-5900 Ethernet intelligent environmental monitoring terminal was launched, successfully deployed at Baidu's Yangquan Data Center. The environmental monitoring software was also upgraded that year to support a multi-parameter environmental monitoring system, further expanding its functional range.

Additionally, the company obtained Internet Data Center (IDC) business qualifications in the same year.
We maintain absolute transparency regarding our credentials, manufacturing process checkpoints, and industrial certifications. Here are our certified verifications and trade displays.
Selecting a reliable custom sensor manufacturer involves verifying not just their product datasheets but their capacity to adapt designs to dynamic operating systems. Here are the key technical and commercial metrics global sourcing managers evaluate:
A standard sensor connected to the internet can be a weak point in corporate network security. Our systems support custom SNMP v3 encryption standards and access control lists. Modbus TCP functions can be mapped to custom register parameters, preventing open, unsecured write access.
Cheap sensors typically drift by more than 1.5% RH every year, which requires frequent recalibration visits. Our premium Sensirion and Bosch chipsets exhibit less than 0.25% RH and 0.03°C annual drift, meaning the units only require standard validation every 2-3 years, saving thousands in operational overhead.
With dual assembly redundancy and long-term contracts for core silicon microchips, Beijing Yingchuanglihe guarantees constant delivery schedules even during global chip shortages. Our 5 automated production lines can scale from small prototype runs of 100 units to bulk logistics volumes of 10,000+ units.
