3. Setup & Installation

3.1. WS90 Outdoor Sensor Installation

Proper installation of the outdoor sensor is crucial for accurate readings. Choose a location that is open and free from obstructions, such as a farm, garden, or driveway.

3.1.1. Mounting

You can attach the WS90 sensor to a pole (not included) with a 1.0-inch diameter. The mounting hole is designed to fit this size. Ensure the pole is securely attached to a permanent structure for stability.

3.1.2. Power Supply

The WS90 is primarily solar-powered. For backup, insert 2 x AA 1.5V batteries (not included). Rechargeable Li-batteries are recommended. For the auto-heater function, an external power cable (sold separately) is required.

Important Power Supply Notes for Auto-Heater:

• We recommend using a 12V power supply for the auto-heater, as it efficiently melts snow covering the battery compartment, which can affect wind speed measurement. A 12V supply also allows for longer power cable runs.
• If remote power is not needed, a 5V power supply can be used, but the heating plate will be less efficient, and snow melting will be slower.
• CRITICAL: The supply voltage range can only be 5V to 20V. Exceeding this range is dangerous and will damage the WS90.

3.1.3. Snow & Ice Considerations

Snow and ice can affect the accuracy of readings. The WS90 has a heating plate to mitigate this:

• Top Snow (①): Snow on the very top cannot be heated by the heating plate. It must be manually cleared to prevent interference with solar power supply and rain measurement.
• Middle Snow (②): Snow in the middle affects wind speed measurement. The heating plate is located here. Connect the heating cable (③) to melt this snow.

3.1.4. Bird Spikes Installation

The WS90 comes with bird spikes to deter birds from landing on the sensor, ensuring uninterrupted operation and data accuracy. Follow these steps for installation:

1. Step 1: Insert the stainless steel strap into the silicon strip. Ensure the protruding part of the stainless steel and silicon strip are on the same side.
2. Step 2: Bend the assembly into a circle. Ensure the pin holes are all facing up and leave some space before finishing the circle for the next operation.
3. Step 3: Set the formed circle on the rain gauge.
4. Step 4: Tighten with needle-nose pliers. Hold the pliers and turn to tighten the stainless steel, cutting off any excess length.
5. Step 5: Insert the stainless steel needles into the designated holes.

5.2. Sensor Replacement

While built to last, the Temperature and Humidity Sensor Kit within the WS90 can be replaced if necessary. Refer to the detailed diagrams for accessing and replacing this component.

6. Troubleshooting

6.1. Rainfall Accuracy

The WS90's haptic rain sensor is generally accurate, but under certain conditions (e.g., specific raindrop sizes, high wind speeds), minor deviations in daily rainfall readings may occur. If highly precise rainfall data is critical, consider using the WH40 Rain Gauge in conjunction with the WS90 for comparative analysis. For general use without strict per-rain event accuracy requirements, the WS90 performs well over time.

6.1.1. Calibrating WS90 Rainfall

The WS90 allows for user calibration of the rain sensor. To perform proper calibration:

1. A reference for rainfall recording is needed, ideally with the ability to capture rain rate. The WH40 Rain Gauge can serve this purpose.
2. You can adjust five rain gain parameters: Piezo Rain1 to Rain5. Typically, leave Rain1 as is unless consistent results indicate otherwise.
3. If you have recorded rain data (e.g., 6.0mm from reference, 7.5mm from WS90), you can adjust the gain. For example, set Rain4 gain to 6/7.5 = 0.8. For simpler handling, you can initially set Rain2, Rain3, Rain5 to 0.8. Only when different rain rates are recorded, divide the WS90 rain by 0.8 to get 1.0 rain, then recalculate (Reference/WS90/0.8) and precisely fill in the corresponding rain gain setting.

6.2. Connectivity Issues

If you experience issues with data transmission or connectivity:

• Check Power: Ensure both the WS90 (solar/batteries) and GW3000 (USB) are powered on.
• Network Connection: Verify your Wi-Fi or Ethernet connection to the GW3000. Ensure your router is functioning correctly.
• RF Frequency: Confirm that your device's RF frequency (e.g., 433MHz, 868MHz, 915MHz) matches the regional standard for optimal communication between the sensor and gateway.
• Obstructions: Minimize physical obstructions between the outdoor sensor and the gateway to ensure a clear signal path.
• Reset: If issues persist, try resetting the GW3000 Gateway using the factory reset button (refer to Figure 2.5).

8. User Tips

• Optimal Placement: For the most accurate wind and rain readings, ensure the WS90 is mounted in an open area, away from buildings, trees, or other obstructions that could interfere with airflow or precipitation.
• Battery Choice: While AA batteries are supported, using rechargeable Lithium-ion batteries for the WS90 backup power can provide longer life and better performance in cold weather.
• Rainfall Accuracy: If highly precise rainfall data is critical for your application, consider supplementing the WS90 with a dedicated tipping bucket rain gauge like the Ecowitt WH40. The WS90's haptic sensor is excellent for general use and low maintenance, but the WH40 offers a different measurement principle that some users prefer for specific accuracy needs.
• Regional Frequency: Ensure you select the correct RF frequency (433MHz, 868MHz, or 915MHz) for your region to guarantee proper communication between the outdoor sensor and the GW3000 Gateway.
• SD Card Formatting: If using an SD card larger than 32GB for local storage, remember to format it to FAT32 using a reliable tool like Rufus on your computer before inserting it into the GW3000 Gateway.
