Dragino WSS-22, Wind Speed and Wind Direction Sensor, RS485

The Dragino WSS-22 captures wind speed and wind direction in a combined device and outputs both values via RS485. The polycarbonate composite housing is corrosion- and rust-proof, while a smooth internal bearing system ensures a starting threshold of at most 0.3 m/s and stable measurement values. The sensor is designed for the Dragino WSC2-L weather station and comes with a 2 m connection cable.

Main features:

• Wind speed and wind direction in one sensor, measuring range 0 to 60 m/s and 0 to 360°
• Low starting threshold of ≤ 0.3 m/s due to smooth bearing system
• Corrosion-resistant polycarbonate composite housing for permanent outdoor use
• RS485 interface with Modbus command set, can be operated directly on the WSC2-L main unit (default baud rate 4800)
• Low power consumption of 13 mA at 12 V, power supply of 5 to 24 V DC

Specifications:

• Wind speed measuring range: 0 to 60 m/s
• Wind direction measuring range: 0 to 360°
• Starting threshold: ≤ 0.3 m/s
• Wind speed accuracy: ±(0.3 + 0.03 × v) m/s (v = wind speed)
• Wind direction accuracy: ±1°
• Supply voltage: 5 to 24 V DC
• Power consumption: 13 mA at 12 V
• Interface: RS485
• Default baud rate (with WSC2-L): 4800
• Cable length: 2 m
• Housing: Polycarbonate composite
• Operating temperature: -30 °C to +70 °C
• Operating humidity: < 100% RH, non-condensing
• Dimensions: 26 × 22.5 × 21 cm
• Weight: 585 g
• Scope of delivery: 1 × WSS-22

Note: For correct wind direction values, the sensor must be aligned to the north during installation; see the user manual.

Areas of application:

• Agricultural weather stations based on the Dragino WSC2-L as basic equipment for wind and direction data
• Crop protection, to determine spraying windows with a low risk of drift based on the current wind speed
• Greenhouse and building automation, e.g., closing ventilation flaps or retracting awnings and blinds in strong winds
• Site assessment and environmental monitoring, e.g., recording the prevailing wind direction for odor or dust dispersion
