Key features

Emits monochromatic single-wavelength light and analyzes reflected spectra to classify dry, damp, wet, waterlogged, iced, and snowy conditions without physical contact or road surface damage.

Outputs water accumulation thickness at 0 to 2mm, ice thickness at 0 to 2mm, and optional snow depth at 50 to 2500mm simultaneously.

Integrated lens heating element activates automatically to prevent icing or frosting on the optical lens during freezing conditions, maintaining spectral measurement accuracy through winter storms.

Built-in laser enables precise targeting of the measurement spot during installation. Live angle value is readable via configuration software, with recommended range of 10 to 40 degrees.

Measurement distance and spot diameter are configurable by adjusting height and angle, covering different road widths and installation heights across highways, bridges, and airport runways.

Outputs a continuous wetness index from 0.00 (dangerous) to 1.00 (dry) alongside categorical road state codes, enabling quantified friction risk assessment beyond simple wet or dry classification.

Power input circuit features a dual design combining anti-reverse connection protection and self-recovery fuse, preventing damage from field wiring errors or instantaneous power supply anomalies.

Monochromatic laser emitter paired with optical filter blocks sunlight and roadside lighting from corrupting reflected spectral readings, maintaining accuracy in exposed daytime highway environments.

Outer housing undergoes anti-corrosion surface treatment, resisting degradation from rain, road deicing agents, salt spray, and chemical runoff in long-term roadside installation environments.

8 baud rate options from 1200 to 115200 bps, enabling flexible integration into highway management, airport, and tunnel monitoring systems.

AI-Powered supplier vetting

SummarySHANDONG RENKE CONTROL TECHNOLOGY CO., LTD. is identified as a Jinan-based trading company operating in manufacturing-related industries, including integrated circuits and environmental monitoring instruments. The supplier reports ISO9001:2015, RoHS, CE, and FCC certifications. It provides extensive customization and ODM services, has introduced new products within the past year, and reports OEM service for well-known brands. Production-related information includes sensor productivity of 400,000 pieces and five quality inspectors, although finished-product inspection has instructions but no written records. The supplier lacks inventory, overseas warehouses, overseas agents or branches, and a valid manufacturing-capacity contract with affiliated subcontractors. Financial records are referenced for 2022–2024, but no monetary figures or detailed financial indicators are provided. Customer evidence is limited to one associated buyer name and does not establish the scope or quality of completed projects.

CertificationsThe supplier reports an ISO9001:2015 certificate and product certifications including RoHS, CE, and FCC. These certifications explicitly support quality-management and product-compliance capability.

After-Sales capabilityThe supplier reports no inventory capability, no overseas warehouse, no overseas showroom, and no overseas agents or branches. It also reports serving zero countries overseas, so the provided evidence does not demonstrate strong after-sales coverage, particularly internationally.

R&D capabilityThe supplier reports new products within the past year, provides ODM services, and offers customization from samples, designs, and full specifications. However, it reports no available SDK, so innovation capability is supported in product development and design services but not across all technical-development resources.

Production capacityThe supplier reports sensor productivity of 400,000 pieces, five quality inspectors, and production equipment including an MST mounter and auto-soldering and soldering capabilities. Nevertheless, it has no valid manufacturing-capacity contract with affiliated subcontractors, and its inspection and supplier-assessment procedures lack written records, limiting assurance of production control.

Customization capabilityBoth reported design-service fields list customization from samples, designs, full customization, minor customization, and flexible customization. The supplier also reports ODM capability, providing explicit evidence of broad customization support.

Product Q&A

Q:What is included in the road condition sensor package?

Road condition sensor*1 Cross arm*1 Clamp*1 Mounting screws (M5*55 hexagon screws*3, M5 nuts*3, M8*50 hexagon screws*3, M8 nuts*3)

Q:How to wire the road condition sensor?

Our sensor uses a wide voltage, and the power input can be 11~28V. When wiring the RS485 signal line, please note that the A and B lines cannot be connected in reverse, and the addresses of multiple devices on the bus cannot conflict. Specific wiring: the brown line is the positive power supply, the black line is the negative power supply, the yellow line is 485-A, and the blue line is 485-B.

Q:What are the functions of road surface sensors?

Road condition sensors can monitor a variety of road information in real time and provide key data for transportation, aviation, tunnels and other fields. Specific functions include: 1. Detect whether there is water accumulation, ice, and snow on the road. 2. Measure road temperature. 3.Measure road humidity.

Q:What are the types of road condition sensors?

Road condition sensors are mainly divided into two types: remote sensing and embedded. The remote sensing type is based on optical principles. It detects the thickness of water, ice and snow on the road surface according to the different infrared spectral characteristics of water, ice and snow. The embedded type integrates multiple measuring probes and directly contacts the road surface. It can measure road surface temperature, water film height, ice thickness, friction coefficient.
