1. Stop Cleaning Your Rain Gauges: The End of Mechanical Failure
Mechanical tipping buckets are a legacy liability. In the field, they are a magnet for bio-fouling—leaves, bird droppings, and debris that lead to clogging, data drift, and costly “truck rolls” for manual cleaning. For a Senior IoT Architect, these are mechanical points of failure that kill ROI.
The future is optical. We’ve replaced moving parts with a maintenance-free optical dome. No clogging, no mechanical wear, and zero manual intervention. By eliminating site visits, you’re not just upgrading a sensor; you’re slashing OPEX and ensuring the integrity of your data stream in the most punishing environments.
2. The Next-Gen Optical Rainfall & Illumination 2-in-1 Sensor
One compact footprint. Two critical data points. This industrial-grade sensor measures both precipitation and light intensity simultaneously. Engineered within a tight ϕ82mm×80mm form factor, it utilizes a rugged ABS body capped with a special organic material dome. This isn’t just a cover—it’s a precision-engineered filter that allows for high-accuracy sensing while shielding internal components from the elements.

4. Why This Sensor is a Game Changer
- 6-Probe High-Precision Array: Unlike single-beam sensors, our built-in 6-probe optical array provides multi-angle redundancy, ensuring extreme sensitivity and consistent data even during erratic storm patterns.
- Auto-Zero Calibration (The 0000H Advantage): To prevent cumulative error reporting, the sensor automatically clears the 0000H register upon every power-on. This ensures your cloud dashboard starts with a clean, verified slate every time the system cycles.
- Total Interference Immunity: The special organic material dome is designed to eliminate interference from sunlight and visible light. It filters out the noise, providing high precision and a significantly longer service life than standard plastics.
- Pulse Signal Precision for PLC Integration: For those utilizing pulse outputs, the sensor triggers a precise 50ms pulse signal for every 0.1mm of rainfall detected, allowing for seamless integration with industrial controllers.
- Maintenance-Free ROI: By moving to an optical solid-state design, you eliminate the “clogging cycle.” This translates to higher data availability and a massive reduction in long-term maintenance costs.
5. Real-World Applications: Maximizing Infrastructure Value
Smart Light Poles: Low Wind Load, High Intelligence
With its small footprint and aerodynamic profile, this sensor is designed for cross-arm mounting on urban smart poles. It provides the hyper-local environmental data needed for adaptive street lighting without adding significant wind load to the structure.
Precision Agriculture: Maximize Yield, Minimize Waste
Hyper-local data is the backbone of AgTech. By monitoring exact rainfall and light levels in fields and greenhouses, growers can automate irrigation logic, reducing water waste and maximizing crop yields based on real-time soil needs.
Industrial Parks & Research: Compliance-Ready Data
For industrial facilities and scientific research, data fidelity is non-negotiable. The rugged −40∘C to 60∘C operating range ensures environmental compliance and high-fidelity data collection in any climate.
Integrated Weather Stations: Modular Scalability
Build a full-stack solution. This 2-in-1 sensor is designed to interface directly with small ultrasonic wind speed and direction sensors, forming a complete, maintenance-free weather station for remote deployments.
6. Data Integration: From Sensor to Screen
Complexity is the enemy of deployment. Our Plan 1 architecture allows for immediate local monitoring. By connecting the sensor to a customer-provided PC via a 485-to-USB module, you can view real-time data and analyze trends through professional monitoring software—no complex cloud configuration required for initial site testing.
Pro Tip for Buyers: To meet global demand, products are shipped in two physical styles (“Old Style” and “New Style”). Rest assured, both versions house the exact same internal optical hardware and deliver identical performance.
7. Frequently Asked Questions (FAQ)
Q: Can it integrate with existing weather stations?
A: Absolutely. It is specifically designed to be used in conjunction with ultrasonic wind sensors and small weather station clusters for a comprehensive environmental profile.
Q: Is the measurement affected by high-noon sunlight?
A: No. The specialized organic material used in the dome is specifically engineered to eliminate sunlight and visible light interference, ensuring your Lux readings and rain counts remain accurate.
Q: What happens if the power cuts out?
A: Upon power restoration, the device performs an auto-zero calibration. It clears the 0000H register to ensure the system recalculates rainfall from a fresh baseline, preventing the reporting of stale or corrupted data.
Q: How difficult is the installation for field technicians?
A: Extremely simple. The unit is small, light, and portable. It’s designed for rapid mounting on poles, cross-arms, or flat surfaces, making it the preferred choice for large-scale IoT rollouts.
