WS200-UMB Smart Weather Sensor
Compact all-in-one weather sensor for measurement of wind direction and speed.
From the WS product family of professional intelligent measurement transducers with digital interface for environmental applications for measuring wind direction and speed. One external temperature or rain sensor is connectable.
- Wind direction and speed
- Ultrasonic/Wind
- Wind detection with birdproof construction. Compact all-in-one weather sensor, low power, heater, maintenance-free operation, open communication protocol.
- RS485, 2-wire, half-duplex, SDI-12
- 8371.U01
Advantages of the Smart Weather Sensor WS200
- Measuring wind direction and speed insusceptibly to bird nesting thanks to roofed construction
- Built-in data pre-processing, universal interfaces and selectable output protocols
- Compatible with many commercially available Met/HydroMet dataloggers and PLS systems thanks to an open communication protocol
- Maintenance-free operation – no moving parts that can wear out
- Suitable for all climate zones; also for solar-powered automatic meteorological stations
Examples of use of the Smart Weather Sensor WS200
The robust and maintenance-free smart weather sensor WS200 is designed for professional meteorological applications in all climate zones. It delivers reliable data, even in extreme ambient conditions.

WS product family: Communication after protocol change
How to communicate with a WS-Sensor and the UMB-config-Tool if the protocol was changed for example to Modbus or SDI-12?
After a Reset ( switching On/Off the sensor) every WS-Senor will start up for the first 5 seconds in UMB-protocol and the standard baud rate of 19200Bd. Independend to the configured protocol and baudrate settings of the WS-Sensor.
In this first 5 Seconds you will be able to connect via UMB-config-Tool to the WS-Sensor after this first command was send the UMB-protocol will stay for 10 minutes after that it switches back to the original configured protocol. This Time will always be extended to 10 minutes if a new UMB command was send.
WS product family: SDI-12 wiring plan for Device version >= 42
How to connect a WS-sensor with a device version >= 42 (hardware version >=14) to a SDI-12 system?
The wiring plan has changed compared to the wiring plan of older WS-Sensor device versions.
The new wiring plan is:
- +VDD = brown
- GND = white
- SDI12_Signal = yellow
- SDI12_GND = white
This is also mentioned as a note in the latest WS-sensor manual in the section 8 Connections
