Overview

Setup Guide

Preparations

1. Open the package.
2. Preparing the receivers (gateways and consoles) to pair with the WS90.

Install batteries in the sensor package
Insert 2*AA batteries into the battery compartment after opening the battery compartment with a screwdriver, when the LED on the back of the sensor package lights up for 3 seconds and blinks every 8.5 seconds, make sure that the sensor is transmitting data. If the light does not come on for 3S, you can press the “Reset” button to start over. Make sure it blinks every 8.5 seconds.

Figure 3: Battery installation diagram

Note

Please make sure the battery is inserted correctly for its polarity as the system needs its initial power from this backup battery to start up the system before the solar panel charges up the accumulator and supply system power afterward. when in high altitude areas, during wintertime, the sunshine time is short, and the system needs to be powered from this backup battery, we recommend Lithium batteries to be used for cold weather climates. Please avoid alkaline batteries, especially when the internal heater is to be activated during cold and wet weather conditions as when the heater is activated, the trapped heat inside will warm up internally, and alkaline batteries are extremely susceptible to leakage when the temperature is over certain limits. Alkaline batteries can be used also, avoid rechargeable battery type of NiMh or NiCd.

Ultrasonic anemometer with piezoelectric assembly

Before you mount
Before mounting the outdoor sensor in a permanent location, you should test the sensor wireless connection in a temporary location, and make sure that the sensor has a good station to show the data on the gateway or console. At the same time, you can adroitly use the various functions and familiarize yourself with the performance of the device.

Mounting
You can attach a pole (not included) to a permanent structure and then attach the sensor package to it (see Figure 4). The install hole will accommodate a pole diameter of 1.0 inch (pole not included).If you don’t use an external heater, you can put the heater cable inside the pole fixing thread, which can make the setup looking tidy.

Make sure the mounting pole is vertical, or very close to it. Use a level as needed. The WS90 has the extension cable to connect the waterproof adapt 12V. As Figure 5 show:

1. The extension cord can also power the entire sensor, not just melt the ice! Now you will need to align the whole package in the proper direction by rotating it on top of the mounting pipe as needed.
2. When you get the outdoor sensor WS90, try to turn left or turn right to confirm how to screw the bottom threaded cover. If you can not confirm the direction. Locate the arrow labeled “NORTH” that you will find on top of the connector tube of the sensor package. You must rotate the whole sensor package until this ar row points due “NORTH” (synchronize the direction on the phone after opening the compass APP), and screw the bottom threaded cover to the direction of the “NORTH”, As the picture shows:

To achieve proper alignment, it is helpful to use a compass (many cell phones have a compass application).

Note:
In the Southern Hemisphere, it is not necessary to change the orientation to“SOUTH” as its solar panel is a rounded type and it is orientation-free for its charging capability. Make sure the mounting tube for the sensor package is installed vertically (use a level at 90-degree offsets around the tube). Adjust the mounting pipe as necessary. Next, also make sure the mounting of the anemometer body on the pipe is level. If it is not, wind direction and speed readings may not operate correctly or accurately. Adjust the mounting assembly as necessary. Make sure you check, and correct if necessary, the north orientation again, as the final installation step, and now tighten the bolts. Do not over-tighten, but make sure strong wind and/or rain cannot move the sensor package.

• The wind gust reading will be the max wind speed in the past 28s.
• When the wind speed is lower than 5m/s,the dispersion of wind direction will increase.
• The primary power source for the sensor is the solar panel. When available solar power (light over recent period) is insufficient, the batteries will be used.

Attention

About daily rain deviation

The daily rain deviation of WS90 is very small in the long run, but under certain conditions, the deviation can be larger: as the raindrop size and wind speed can have different impacts on the sensor output which lead to this variance. The WS90 product suffer from this imperfectness. If you are very demanding on rain data accuracy, we suggest you buy WH40 and use it together with WS90. If there is no precise requirement on data of each rain, then WS90 is just fine: After all the device works well after a longer run time.

How to calibrate WS90
Ensure your mobile phone and gateway in the same router, the WS90 has been paired with the gateway.

1. Set the Calibrate in the Ecowitt app If you have data from a relatively accurate weather station. You can use the data to do the calibration.
2. Make sure your mobile device is connected to the same Wi-Fi network.
3. Click “…” on top right corner and choose “Calibration”.
4. For a certain parameter(Use Indoor temperature as an illustration in Figure 22). Calculate the offset of data from the accurate weather station and ecowitt sensor.
5. Fill in the offset got from step3, click Save.

The WS90 is equipped with a haptic rain sensor, and the system offered a way that users can calibrate the rain sensor accuracy by themselves. To carry out a proper calibration, please check the following:

1. A reference will be needed to record the rainfall value, and also it is quite important to have the ability to record the rain rate. For this, our WH40 rain sensor can be used for this purpose.
2. There are five rain gain parameters you can set: Piezo Rain1: Rain5. So we leave Rain1 as it is unless you can confirm it made constantly same result, and then you can adjust this.
3. Have rain data recorded, like this: we set rain4 gain to 6/7.5 = 0.8. For easier handling, you can set rain2:rain3:rain5 all the 0.8 for the time being. Only when different rain rates are recorded, you have the WS90 rain divided by 0.8 to get 1.0 rain, and then have the (reference/WS90/0.8) calculated again, and fill up the corresponding rain gain setting precisely.

Wind speed 0 calibrations for WS90.

1. In a windless room, research a soft cloth to cover the top cover and the wind speed area of the WS90, after holding the CAL button for 3 seconds, the light will be bright for 5 seconds and then start to flash, after waiting the light has closed, and the wind speed will be reset to zero. As the picture shows:
2. In the usual state, press the CAL button three times to turn the LED off to stop the light flash. After the LED has been closed, if want to restart the light function: Press the reset button to restart it.
