Dragino WSS-08 | RS485 Optical Rain Gauge Sensor

The Dragino WSS-08 is a professional-grade optical rain gauge designed to provide highly accurate precipitation data for smart agriculture and environmental research. Unlike traditional mechanical tipping buckets, the WSS-08 uses optical sensing to eliminate errors caused by mechanical wear or clogging from debris. This sensor converts rainfall into digital pulses, where each pulse represents 0.1mm of precipitation, ensuring precise data even during light rain events.

Core Capabilities

High Intensity Range Capable of measuring extreme rainfall intensities up to 24mm per minute. Industrial Durability Operates reliably in harsh conditions from -40°C to +60°C and up to 99% humidity. Infrared Detection Compact 6cm sensing diameter utilizes optical beams for low-maintenance, debris-resistant operation. Wide Voltage Support Compatible with power systems from 9V to 30V DC, ideal for solar or industrial power loops.

Primary Applications

• Precision Farming: Monitor rainfall to optimize irrigation schedules and conserve water resources. • Flood Warning Systems: High intensity 24mm/min detection for rapid-response meteorological alerts. • Environmental Research: Gather accurate atmospheric data for climate studies and laboratory analysis.

Technical Integration

The WSS-08 is designed to integrate seamlessly with the Dragino WSC2 Series main process unit. It provides a standard pulse signal that can be transmitted over LoRaWAN, NB-IoT, or LTE-M networks to professional IoT platforms such as ThingsEye.io. For large-scale weather station layouts requiring multiple sensors, it can be combined with other WSS-series probes using the DR-F6C-4M adapter cable.
