Direct supply and engineering options from our high-precision Beijing laboratory and automated production assembly.
In the age of hyper-scale cloud infrastructure, smart agriculture, and automated factory supply chains, sub-system monitoring must meet stringent metrics: absolute precision, long battery life, and superior wall-penetration capabilities. Traditional protocols, such as Wi-Fi or Bluetooth, face structural boundaries due to high energy consumption and limited signal propagation. To bypass these limitations, the global IoT community has converged on LoRa (Long Range) and LoRaWAN technologies as the standard for distributed temperature, relative humidity, and barometric telemetry.
At the center of this technological leap is Beijing Yingchuanglihe Electronic Technology Co., Ltd. (established in 2007). With 18 years of specialized engineering in high-stability telemetry, we design integrated sensor systems configured to monitor complex metrics including dew point, atmospheric pressure, air quality indices (IAQ, CO, O3, TVOC, HCHO, H2S), and soil profiles over long distances.
"Using advanced spread spectrum modulation, LoRa sensors are capable of communicating across distances of up to 15 kilometers in line-of-sight environments, while running on a single lithium thionyl chloride battery for up to ten years."
LoRa operates within sub-gigahertz license-free ISM bands (such as 868 MHz in Europe, 915 MHz in North America, and 470 MHz in China). Operating on lower frequencies allows the signals to bend around obstacles and pass through thick concrete or metal enclosures far more effectively than 2.4 GHz or 5 GHz waves. The core feature of LoRa is the Chirp Spread Spectrum (CSS) modulation. Unlike traditional narrowband signals, CSS transmits data using frequency-swept pulses ("chirps"), which makes the transmission highly resistant to multi-path fading and electromagnetic interference typical in industrial factories.
Our journey represents a history of continuous improvement in network engineering, environmental sensing, and robust factory processes. Here is how we have advanced since our inception:
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 our environmental monitoring software was launched, laying the groundwork for our smart platform.
In collaboration with Mocha Software, a leading domestic network management software company, a series of SNMP protocol-supported environmental monitoring products, TH-5939, were successfully launched.
In partnership with Switzerland's COMLAB, we introduced the TH-5869 protective Ethernet environmental monitoring device, successfully applied in high-speed rail projects including the Beijing-Kowloon, Beijing-Shanghai, and Wuhan-Guangzhou lines.
Cooperating with Founder Technology, we launched the APEM-6100 Ethernet environmental monitoring device, marking our earliest adoption of Power over Ethernet (PoE) technology.
Our collaboration with Foxconn established our products as a recognized benchmark for environmental telemetry inside complex, high-throughput manufacturing plants.
In partnership with Baidu, we deployed our next-generation APEM-5900 Ethernet intelligent terminals within the high-density Baidu Yangquan Data Center. Our software system was upgraded to support wide-scale multi-parameter monitoring.
We launched integrated outdoor cabinet systems and expressway IoT tracking nodes, which were quickly deployed in partnership with Huawei and China Merchants Huaruan for major highway projects.
We designed road-test integrated enclosures and edge-computing gateways for Beijing's automated driving test areas, and supplied environmental monitoring solutions for intelligent high-density computing centers.
Co-founded a dedicated Beidou High-Precision division with the Beijing University of Civil Engineering and Architecture, alongside establishing a specialized smart water pipeline monitoring unit with Beijing Enterprises Water Group.

When global buyers evaluate Chinese LoRa temperature and humidity factories, their focus spans more than unit pricing. It encompasses the raw material pipeline, calibration quality, standard compliance, and deep firmware customization. Yingchuanglihe integrates design, tooling, production, testing, and compliance under one roof in Beijing, providing unique advantages to international procurement teams:
We utilize high-accuracy, long-term stable capacitive sensing chips imported directly from Switzerland (Sensirion) and Germany. This ensures an accuracy of up to ±0.2°C and ±1.8% RH, minimizing drift over years of use.
Our engineering support team offers technical responses within 8 hours. From optimizing LoRa payload decoding to designing custom enclosures, our engineers work alongside your integration team.
Our complete range of sensor models—including Ethernet, Wi-Fi, and LoRa versions—is fully certified under CE, FCC, and RoHS, simplifying customs clearance and local compliance procedures.
Our factory supports customized frequency bands (CN470, RU864, IN865, EU868, US915, AU915, AS923) to match specific regional networks. Additionally, our software platforms support multiple protocols—including SNMP, Modbus TCP, MQTT, and HTTP—ensuring integration with SCADA systems, private clouds, or platforms like AWS IoT Core and Azure IoT Hub.
Proven reliability verified through ISO audits, CE approvals, and regular appearances at global trade exhibitions.
Expert technical insights to assist in planning your next environmental monitoring project.
