Dragino WSS-26 RS485 Total Solar Radiation Sensor
The Dragino WSS-26 is an RS485 total solar radiation sensor designed to measure solar radiation across a spectral range of 0.3–3 μm (300–3000 nm). It uses a high-precision photosensitive sensing element with a precision-machined PTFE radiation cover to reduce environmental interference and provide stable solar-radiation measurements for weather stations, agriculture, meteorology, renewable-energy projects and environmental monitoring systems.
The WSS-26 measures radiation intensity from 0 to 2000 W/m² with 0.1 W/m² resolution and ±3% accuracy. It communicates through RS485, operates from 5–24V DC, and is compatible with the Dragino WSC2-L Weather Station Controller. The sensor can also measure reflected radiation when the sensing surface faces downward, while a shading ring can be used for scattered-radiation measurement.
