SWS-100 Weather Sensor: Key Features and Specifications
The SWS-100 Weather Sensor is designed for monitoring roadside weather conditions, particularly for identifying fog, haze, rain, drizzle, snow, and other visibility reductions. It is ideal for roads, motorways, and tunnels, and integrates seamlessly into Intelligent Transport Systems (ITS). The sensor features automatic equipment switching through relays, providing real-time weather warnings.
Core Features:
- Visibility Measurement: Range of <10 m to 2 km (1.2 miles) with 10 m increments, designed to measure reductions caused by fog, haze, smoke, sand, drizzle, rain, snow, and other precipitation.
- Precipitation Identification: Identifies precipitation types and reports WMO 4680 codes.
- Data Outputs: Offers both instantaneous and averaged visibility outputs.
- Relay Functions:
- Relay 1: Fault indicator.
- Relay 2: Configurable for visibility threshold.
- Relay 3: Can be configured for precipitation or snow detection, or a second visibility threshold.
