I will refresh the topic a bit, but I have a reason. Last week finally I received from Ecowitt a new upgraded version of the WS80 anemometer sensor with ultrasonic measurement of wind speed and its direction, detection of temperature and humidity, solar radiation and UV index.
A new feature of my sensor is built-in heater for possible snowfall or freezing rain during winter. For the time being, this does not seem to be the case in my region, to test this maybe I will have to wait until January.
The first thing that catches the eye is the small size. It's an integrated station, so there's little to assembly. You only need to screw the mount. The whole seems to be done solidly.

As you can see, the cable goes off from the device, which is connected to the heater and should be switched on at freezing temperatures or to melt snow / freezing rain.There is a tight connection and a 20-meter cable ending with a USB plug.

In the center of the round solar panel is a light and UV sensor with an LED indicating data transmission (every 4.75 sec).

Here you can see a new element, maybe it is the effect of searching for solutions for some disturbances in very heavy rain.
Aluminum mesh - surface tension conditioner layer - a patented cover that prevents the formation of water drops that interfere with wind measurements.

The sensor is ready for installation. Above the radiation shield for temperature sensor is also a reset and calibration button. In general, they are useful when the measurements faulty indicate the wind in the presence of silence, the data is not read or we insert spare batteries. However, so far I have not had such a case and it is better not to use them for no reason.

On the mounting arm side there is a plug on the USB plug used to update the firmware, although I find it unhandy after installing the sensor on a mast or roof. However, it gives you the chance to fix any defects.

I quickly mounted the sensor to the rain gauge post to compare the sizes of both sensors, which basically form a coherent whole, because the WS80 will not measure rainfall alone.

Eventually I placed the WS80 sensor on the same pole as the WS68 from Ecowitt to have a good comparison of the two. It's about 9 meters above the ground. For now, the first impressions are very positive.
The sensor itself will not work without a GW1000 gateway or Ecowitt HP2553 console (on the right). A console n the left comes from HP3501 weather station.
You can observe differences between both types of anemometers:

Above all, however, I am impressed with the frequency of measurements - every 5 seconds. On the console or on the WSView application you can see these changes almost every now and then, which gives a good impression of catching every gust. There is no inertia when measuring with ordinary vanes. The sensitivity se...
