WS-80 Ultrasonic Wind sensor array
Mandrake:
As promised here are the first shares of the new sensor from Ecowitt
This is a combined Ultrasonic wind speed and direction (anemometer) with integrated UV, Temp and humidity
The range for this device has been improved and Ecowitt say they expect this to work up to 300M in ideal circumstances in conjunction with the latest version of the gw-1000

Features:
1.Measures wind speed/direction, temp/humidity, solar radiation/uv
2.Supports updating firmware with USB cable. (in the photo's I have attached this port can be seen with a plastic plug covering it just underneath the solar cell at the top)
Specifications
1. Wind speed: Range: 0~40m/s; Starting wind speed: 0.5m/s; Accuracy(pending).
2. Wind direction: Range: 0~359 degrees; Accuracy: 10 degrees.
3. Temperature: Range: -40~60ˇăC; Accuracy: 1C.
4. Humidity: Range: 1~99%; Accuracy: 5%.
5. Light intensity: Range: 0~300Klux; Accuracy: 15%.
6. Ultraviolet: Measurement level 1~15; Accuracy: 2.
7. Battery voltage measurement: Range: 0~3.3V; Accuracy: 0.1V.
8. Static current: 30~50uA.
When the maximum wind speed of the last 4s is >=5m/s, the wind speed is detected by 1s; when the maximum wind speed of the last 4s is >=3m/s and less than 5m/s, the wind speed is detected by 2s; when the maximum wind speed of the last 4s is <3m/ s, the wind speed is detected by 4s.
Please note the wh80 sensor can have a heater under the sonic reflecting surface and this can be used to melt the snow builds up during wind season and make the item still functional. Among the sample we sent, we didn't have the power cable installed for heater use.
krojan:
Have you already activated the WS80 sensor?
Have you compared his readings with another anemometer?

Just arrived today for me also, tomorrow I will install at about one meter far from my vp2

ws80 installed now
on the rear of ws80 there is a meteoshield standard with wh-32 sensor

krojan:
Are the WS80 sensor and Davis anemometer too low? It should be 10m (about 33 feet).
Trees that can be seen in the background do not affect wind measurements?
