Dragino WSS-26 | Industrial Total Solar Radiation Sensor

The Dragino WSS-26 is a professional-grade solar radiation sensor designed for long-term, high-accuracy monitoring of atmospheric solar energy. By capturing short-wave radiation in the 300nm to 3000nm spectrum, it provides critical data for calculating solar gain, assessing photovoltaic potential, and studying ecological evapotranspiration. When connected to a WSC2-L Main Process Unit, this sensor enables robust data transmission via LoRaWAN, allowing operators to monitor remote solar farms or research sites with industrial reliability.

Core Capabilities

Wide Sensing Band Captures total radiation from ultraviolet to near-infrared (0.3μm to 3μm). Reliable Year-Over-Year Maintains high performance with a yearly stability rating of ≤±2%. Accurate Cosine Correction Optimized cosine response (≤7% @ 10° sun angle) for consistent measurement throughout the day. Standard RS485 Low-noise digital communication compatible with PLCs and industrial IoT transmitters.

Primary Applications

• Solar Power Monitoring: Measure the efficiency of solar panels and verify if energy outputs match radiation levels. • Smart Agriculture: Assess photosynthesis conditions and water evaporation rates for precision irrigation planning. • Meteorology & Climate: Professional-grade data collection for environmental research and weather forecasting.

Technical Integration

The WSS-26 utilizes a standard RS485 interface and is natively supported by the Dragino WSC2-L LoRaWAN Main Process Unit. This integration allows for the rapid creation of a complete weather station when combined with wind, rain, and pressure sensors.
