Modern commercial and industrial architectures demand absolute precision when capturing physical variables such as pressure, temperature, and relative humidity. The rise of hyper-scale data centers, automated pharmaceutical cleanrooms, and intelligent building control loops has positioned the Ethernet-based multi-parameter transmitter at the heart of IoT infrastructure.
At Beijing Yingchuanglihe, we address this requirement by engineering transmitters that merge multiple sensor arrays into integrated, networked nodes. Utilizing state-of-the-art MEMS (Micro-Electro-Mechanical Systems) technology sourced from Swiss and German manufacturers, our devices eliminate the signal degradation risks associated with analog wiring. Instead, they stream calibrated digital data over standardized Ethernet networks using robust communication protocols such as Modbus TCP, SNMP, and MQTT.
By leveraging Power over Ethernet (PoE - IEEE 802.3af/at), system integrators can deploy these sensors with a single Category-5e or Category-6 cable, transmitting both power and operational data simultaneously. This dramatically cuts deployment costs and simplifies post-installation maintenance cycles.
A global pioneer in environmental monitoring solutions and custom sensor engineering since 2007.
Our transmitters utilize high-performance internal sensing components imported directly from industry-leading silicon foundries in Germany and Switzerland, ensuring nominal long-term stability and trace drift rates.
Every device rolling off our production lines is fully compliant with regional regulatory framework requirements, boasting CE, FCC, and RoHS marks for straightforward global importation and installation.
We feature fully modular circuit architectures allowing custom physical probe designs, multi-gas modifications (SO₂, NO₂, CO, O₃, H₂S), specific enclosure branding, and firmware configuration services.

A look at the sensing technologies we are developing for tomorrow's complex industrial needs.
Integrating micro-environmental sensor telemetry with Beidou high-precision satellite positioning. This configuration lets structural engineers trace physical movement alongside localized micro-climate changes in large civil projects like dams, tunnels, and high-voltage transmission lines.
Deploying AI algorithms directly to our edge processor designs. Future transmitters will automatically calculate drift curves based on operational context, utilizing background reference parameters to adjust calibration points without physical technician intervention.
Adopting Single Pair Ethernet (SPE - 10Base-T1L) physical layers to extend Ethernet sensor loops up to 1000 meters. This development will let project managers build unified IP networks over long distances without using local media converters.
How we work with design houses, machinery builders, and integration teams to deliver customized hardware.
Standard enclosures do not always match the physical space constraints of specialized industrial systems. We offer customization of the sensor's physical layout, from remote cable probes to duct-mounted flanged assemblies. Enclosures can be configured in cast aluminum, high-impact polycarbonate, or 316L stainless steel depending on chemical and physical environments.
We can compile custom firmware files to load specialized communication protocols or data formats. Whether you require specific SNMP MIB structures, custom JSON payload formats for REST API requests, or localized Modbus register maps, our software team can write and test the custom code within days.
Our typical OEM design evaluation starts with a complete circuit and mechanical review. We supply prototype evaluation units within 2 to 3 weeks, significantly reducing your development cycle.
