Key features

Detects presence of rain or snow within 0.5 seconds of surface contact, enabling near-instant alarm triggering for greenhouse covers, highway alerts, and weather station event logging.

Alternating current detection method actively prevents electrode oxidation over time, maintaining long-term sensitivity without the signal degradation common in DC-based conductive rain sensors.

Built-in heating element switches on automatically below 15 degrees C, melting snow on contact and enabling reliable snow detection in freezing temperatures where unheated sensors fail entirely.

Maximum heating temperature is 40 degrees C, preventing overheating that would accelerate electrode oxidation and degrade sensing surface sensitivity during extended winter operation.

Recommended 15 degree tilt installation prevents rain and snow from pooling on the sensing surface, ensuring the sensor resets cleanly after precipitation stops without false extended alarm states.

Both alarm activation delay and reset delay are software-configurable, suppressing nuisance repeated alarms in drizzle or intermittent precipitation conditions without missing genuine rainfall events.

Choose RS485 for digital network integration, relay for direct equipment switching, or the combined mode for simultaneous data logging and physical alarm or actuator control in one unit.

Built-in relay supports direct wiring to audible and visual alarms or greenhouse actuators without external relay modules, reducing wiring complexity and component count in control panels.

Full IP68 protection on ABS housing ensures the sensor body remains sealed against continuous rain, snow immersion, and condensation during long-term outdoor installation in exposed locations.

Broad voltage input supports diverse DC power supplies. Normal operation draws only 0.4W, with heating mode consuming 7.5W, enabling solar-powered deployment with appropriately sized panels.

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:How to install a rain and snow sensor?

When installing the rain and snow sensor, keep the sensing surface of the sensor and the horizontal plane at an angle of 15 degrees to prevent the accumulation of rain and snow from affecting the sensor measurement.

Q:What is a rain-snow sensor?

The rain and snow sensor is an instrument that uses the conductive characteristics of rainwater and uses advanced detection circuits to detect whether there is rain or snow.

Q:What is the working principle of the rain and snow sensor?

Rainfall Monitoring: The rain and snow sensor uses grid electrodes on top, utilizing the conductivity of water for detection. When rainwater falls on the sensing area, the electrodes short-circuit, allowing the device to detect the rain. Snowfall Monitoring: The rain and snow sensor can measure snowfall because it has an automatic heating function, preventing snow from freezing or condensing in prolonged sub-zero temperatures and high humidity environments. The heating temperature can be set.

Q:How can I test my rain sensor?

After installing the rain sensor, take a small number of water droplets on the surface of the sensor. If the sensor alarms, it means that the sensor is normal.

Q:How to maintain the rain and snow sensor?

When maintaining the rain and snow sensor, use a clean, dry soft cloth to clean the outside of the instrument to prevent the instrument from being scratched, maintain the integrity of the external protective film, and increase the service life of the instrument. Rough treatment of the instrument will destroy the internal circuit board and delicate structure.
