Dragino WSS-27 | Photosynthetically Available Radiation (PAR) Sensor

The Dragino WSS-27 is a professional-grade industrial sensor designed to measure Photosynthetically Available Radiation (PAR). Essential for smart agriculture and horticultural research, it focuses exclusively on the 400-700nm light range used by plants for growth. By integrating the WSS-27 into a LoRaWAN® network via the WSC2 Main Process Unit, growers can achieve real-time, remote visibility into the light intensity affecting crop health and yield efficiency.

Core Capabilities

Optimized Spectrum Highly selective response within the 400-700nm waveband for accurate PAR data. Granular Monitoring Delivers 1 µmol/m².s resolution with a measurement strength up to 2500 µmol/m².s. RS485 Reliability Utilizes the standard RS485 interface for robust, noise-resistant industrial communication. Field Durability Stable performance with a yearly drift of ≤±2% across wide operating temperatures.

Agricultural Applications

• Greenhouse Automation: Optimize supplemental lighting systems based on real-time PAR levels to save energy. • Precision Farming: Monitor spatial light distribution in large-scale fields for data-driven crop management. • Ecological Research: Professional-grade data collection for photosynthetic studies and climate research.

Technical Integration

The WSS-27 is designed to work seamlessly with the Dragino WSC2 Main Process Unit, which transmits sensor data via LoRaWAN®. This modular architecture allows for the combination of multiple weather sensors (Wind, Rain, CO2) into a single unified dashboard.
