Sorry should have been more forthcoming....its a complete set of instruments barring the rain gauge.
So in short it contains a UV sensor, Temperature and Humidity as well as the Ultra-sonic sensors to measure wind speed and direction.
I expect most folks would pair this with the independent rain gauge to get the full basic set together with a console.
I have been sworn to secrecy on this so long I have almost forgotten what I know about it!
some extra data from the specs..
Features:
1.Measures wind speed/direction, temp/humiidty, solar radiation/uv
2.Supports updating firmware with USB cable.
Specifications
1. Wind speed: Range: 0~40m/s; Starting wind speed: 0.5m/s; Accuracy(pending).
2. Wind direction: Range: 0~359 degrees; Accuracy: ¡À10 degrees.
3. Temperature: Range: -40~60¡ãC; Accuracy: ¡À1¡ãC.
4. Humidity: Range: 1~99%; Accuracy: ¡À5%.
5. Light intensity: Range: 0~300Klux; Accuracy: ¡À15%.
6. Ultraviolet: Measurement level 1~15; Accuracy: ¡À2.
7. Battery voltage measurement: Range: 0~3.3V; Accuracy: ¡À0.1V.
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.
