ECOWITT WS90 Ultrasonic Anemometer with Piezoelectric Rain Gauge Instruction Manual

Ultrasonic Anemometer
with Piezoelectric Rain Gauge, Light &
UV, Thermo-hygrometer Sensors
Model: WS90

Warnings and Cautions

Note:

1. The last firmware in QR code on the box
2. Advance setting on Embedder Web page 192.168.4.1 (You need a computer or phone linking WLAN gateway)

1.1 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 battery for the ultrasonic anemometer, which is primarily for startup and backup power purpose. After setup and during normal operation, the unit is getting its power from solar cell.
Note: 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 formelting accumulated snow or ice, which can influence wind measure meant ccuracysignificantly. Please contact us at support@ecowitt.com for the extension cord information if needed.
1.2 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 turron below 0℃ (30℉ ) and automatically turn off above 10℃ (50℉ ).

Setup Guide

3.1 Install batteries in sensor package
Open the battery compartment with a screwdriver and insert 2 AA batteries in the battery compartment, and press “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 sensor has been put outside for some time, and solar panel has charged up the internal accumulator fully or partially, if you install the 2 AA backup battery, the system might not start up properly. So you can always make a system reset by press 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 solar panel charges up the accumulator and supply system power afterwards. when in high altitude area, during wintertime, sunshine time is short, thus 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 internal heater is to be activated during cold and wet weather conditions as when heater activated, the trapped heat inside will warm up internally, and alkaline batteries are extremely susceptible to leakage when temperature is over certain limits.
3.2 Mount ultrasonic anemometer with piezoelectric assembly
3.2.1 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 performance.
3.2.2 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 inch (pole not included).

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

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

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 labeled “NORTH” that you will find on top of the connector tubeof 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 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.
3.2.3 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 affect 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

4.1 Transmission between gateway and sensor
Transmission distance in open field: 150 m (500 ft.) depend on environment
RF frequency: 433/868/915/920 MHz depending on location
Sensor reporting interval: 8.8 seconds
Note:

• The wind speed is detected by every 2s.
• The wind speed reading will be a real-time value (The latest sampling data will be reporting 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.

4.2 Measurement Specification

0.5m/s; ≥
10m/s, ±5%| 0.1m/s
Wind direction| 0°to 359°| <2m/s, ±

4.3 Power consumption

Note: 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.
