Dragino WSS-21 | Industrial Tipping Bucket Rain Gauge

The Dragino WSS-21 is a high-performance industrial tipping bucket rain gauge designed to convert liquid precipitation into digital pulse signals. Built for long-term outdoor deployment, it features a streamlined design that minimizes errors caused by wind-induced turbulence. As a critical sensor for meteorological monitoring, it provides accurate intensity data through its RS485 Modbus RTU interface, making it an essential addition to the Dragino WSC2-L weather station ecosystem.

Core Capabilities

0.2mm Resolution Captures small rain events with a 0.2mm per tip resolution, ideal for precise irrigation planning. Rugged Engineering Engineered for harsh environments with an operating temperature range of -40°C to +85°C. RS485 Modbus RTU Standard digital output ensures error-free data transmission even over long cable lengths. Solar Ready Optimized for remote sites with low power consumption and flexible 5-24V DC input.

Professional Applications

• Flood Warning Systems: Provide real-time data for catchment management and urban drainage monitoring. • Smart Irrigation: Automate water delivery based on real-time natural precipitation events to conserve resources. • Environmental Research: Gather high-fidelity data for climate studies and local meteorological trends.

Technical Integration

The WSS-21 is designed to be paired with the Dragino WSC2-L weather station main process unit. This integration allows for the transmission of rainfall statistics (Total Rainfall, Daily Rainfall) via LoRaWAN® to any IoT network server. It comes with a 2-meter cable and features a durable ABS shell.
