Pioneering environmental sensing
Beijing state-of-the-art facility
Ensuring highly stable cycle times
Top R&D engineers & service staff
Established in 2007, Beijing Yingchuanglihe Electronic Technology Co., Ltd. has developed into a premier industrial manufacturer specializing in environmental monitoring sensors and IoT systems. With our main headquarters in Beijing, we operate a production facility spanning over 1,500 square meters. Our R&D division has been at the forefront of designing high-precision sensors that measure temperature, humidity, atmospheric pressure, and an extensive array of toxic, flammable, and trace environmental gases.
We pride ourselves on the engineering depth and strict quality control systems. We source core sensing chips from leading manufacturers in Switzerland and Germany to guarantee drift-free performance and exceptional longevity. All our operations are aligned with ISO standards, and our product line is fully certified with CE, FCC, and RoHS. By integrating standard communications protocols such as Modbus TCP/RTU, SNMP, TCP/IP, LoRaWAN, and WiFi, our sensors interface natively with global SCADA, DCIM, and building automation systems.
Why global enterprise buyers trust Chinese supply chains for high-volume, reliable gas sensing equipment.
Operating from Beijing, we leverage the world's most comprehensive electronics supply chain. This proximity ensures instant access to specialized casings, advanced PCB assemblies, and raw materials, reducing lead times from months to weeks.
By blending localized mechanical manufacturing with top-tier imported sensing elements (Switzerland & Germany), we offer products that match or beat European and American performance benchmarks at a fraction of the capital expenditure.
Our in-house R&D team can customize firmware, communications protocols (e.g., configuring custom registers for Modbus), physical enclosure shapes, and multi-gas arrays. This direct line to production ensures customized units match exact client specifications.
Every sensor undergo rigorous, multi-point calibration in dedicated gas chambers. With strict CE, FCC, and RoHS testing protocols built directly into the assembly line, we minimize field failure rates and maximize operational uptime.
Ensuring compliance, efficiency, and safety across various complex physical environments.
Data centers generate enormous amounts of heat and are highly sensitive to humidity and trace gas corrosion. High humidity leads to condensation, while dry air increases static electricity. Trace chemical gases (such as sulfur dioxide or nitrogen compounds) can corrode modern server circuit boards. Our multi-parameter Ethernet transmitters (like the APEM-5930P) provide continuous temperature, relative humidity, dew point, and air pressure data directly to DCIM frameworks over Modbus TCP or SNMP, protecting mission-critical computing servers from environmental damage.
Industrial wells, pipelines, and confined working areas require instantaneous gas logging to prevent toxic gas poisoning or explosive accumulations. Incorporating sensors like the APEM-5930G-O₂-H₂S allows facilities to track oxygen depletion and dangerous concentrations of hydrogen sulfide concurrently. Built-in alarm relays enable the sensor to trigger ventilation fans automatically when threshold limits are breached, ensuring human life and assets are protected.
Pharmaceutical cleanrooms and biotech labs demand strict control over environment differentials to avoid cross-contamination. Our differential pressure and IAQ sensors track pressure differentials down to microbar levels. Meanwhile, in smart agricultural applications, wireless sensors using LoRaWAN technology monitor greenhouse temperature and carbon dioxide concentrations over vast distances, allowing central management systems to adjust fertilization and air ventilation schedules autonomously.
