4. The LED indicator on the sensor package will turn on for 3 seconds and then flash every 8.8 seconds to indicate sensor data transmission.
5. If you miss the initial indication, press the Reset button to start over.
6. Ensure the LED indicator flashes every 8.8 seconds during normal operation.

FAQ

• Q: What should I do if the sensor data transmission indicator does not flash every 8.8 seconds?
  A: If the indicator does not flash as expected, try pressing the Reset button to restart the setup process. Make sure the batteries are inserted correctly and have enough power.

• Q: Can I use rechargeable batteries in the sensor package?
  A: We recommend using standard AA batteries for initial setup and backup power. Rechargeable batteries may not provide consistent performance due to varying power levels.

2. Advance setting on Embedded Web page 192.168.4.1 (You need a computer or phone linking WLAN gateway)

Optional other accessories (sold separately)

Accessories:
12V/1A power extension cord; Bird spikes.

Note:

• Batteries for the sensor package are not included. You will need 2 AA-size batteries for the ultrasonic anemometer, which is primarily for startup and backup power purposes. After setup and during normal operation, the unit gets its power from the solar cell.
• There’s a built-in heat plate in the 7-in-1 sensor package body, if the lowest temperature at your place is below -3°C, or 26.6°F, and the weather is mostly snowy or rainy, then you may need to activate the heater by supplying an external 12V/1A power to the sensor heating element for melting accumulated snow. or ice, which can influence wind measurement accuracy significantly. Please contact us at support@ecowitt.com for the extension cord information if needed.

Features

• Piezoelectric rain gauge;
• Ultrasonic anemometer (start wind speed 0.3m/s);
• Temperature;
• Humidity;
• Solar light intensity and UV index;
• Waterproof IPX5;
• Heater and additional power supply;

Note:
There’s a built-in thermostat inside the anemometer sensor to control the power supply for the heat plate, which will automatically turn on below 0℃(30℉) and automatically turn off above 10℃ (50℉).

Setup Guide

Install batteries in the sensor package
Open the battery compartment with a screwdriver insert 2 AA batteries in the battery compartment, and press the “Reset” button, the LED indicator on the back of the sensor package (item 4) will turn on for 3 seconds and then flash once every 8.8 seconds indicating sensor data transmission. If you did not pay attention, you may have missed the initial indication. You can always press the reset button to start over. Make sure you see the flash once every 8.8 seconds.

If a sensor has been put outside for some time, and the solar panel has charged up the internal accumulator fully or partially, if you install the 2 AA backup batteries, the system might not start up properly. So you can always make a system reset by pressing the “Reset” button.

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 afterwards. 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.

Mount ultrasonic anemometer with piezoelectric assembly

Before you mount
Before installing your outdoor sensor in the permanent location, we recommend operating the device for one week in a temporary location with easy access. This will allow you to check out all of the functions, ensure proper operation and familiarize you with the device’s performance.

Mounting

• You can attach a pole (not included) to a permanent structure and then attach the sensor package to it (see Figure 3).
• The install hole will accommodate a pole diameter of 1.0 inches (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 look neat.

Make sure the mounting pole is vertical, or very close to it. Use a level as needed.

1. If an optional extension cord is added, connect the cord to the connector and insert the USB port into the AC adaptor as Figure 4 shows:

Now you will need to align the whole package in the proper direction by rotating it on top of the mounting pipe as needed. Locate the arrow labelled “NORTH” that you will find on top of the connector tube of the sensor package (item 6). You must rotate the whole sensor package until this arrow points due north. 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.

Reset button and transmitter LED
In the event the sensor package is not transmitting, reset the sensor.

Using a bent-open paperclip, press and hold the RESET BUTTON (item 12) to effect a reset: the LED turns on while the RESET button is depressed, and you can now let go. The LED should then resume as normal, flashing approximately once every 8.8 seconds.

Specification

Transmission between gateway and sensor

• Transmission distance in the open field: 150m (500ft) depending on the environment
• RF frequency: 433/868/915/920 MHz depending on location
• Sensor reporting interval: 8.8 seconds

Note:

• The wind speed is detected every 2s.
• The wind speed reading will be a real-time value (The latest sampling data will be reported to the receiver).
• 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 leads to this variance.
The WS90 product suffers 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
The WS90 is equipped with a haptic rain sensor, and the system offers a way for 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.
