Page 4: Features
3.1 Features Soil Moisture Sensor Measures soil moisture content every 70 seconds. Custom Mode: with 0%AD and 100%AD custom mode to manually calibrate the low/high moisture value so that you can get more accurate result for different soil types. This mode can only be activated through WS View app and in live data display mode. - Page 5 Display Up to 8 channels supported. Channel names can be edited on the Display (for HP2551 only). When uploaded to Ecowitt Weather Server: View current soil moisture data & history records & graph on the website ...
- Page 6 Remote monitoring with smart phone, laptop, or computer by visiting the website Note: The WH51 and WN51 will be recognized as the same sensor type by the software. If you purchased both, they will share the eight channels together and the total quantity of the two sensors could not exceed eight.

4. Setup Guide 4.1 Install batteries 1.Open the battery cap of the soil moisture sensor 2.Insert one AA battery and close battery cap. 3.After inserting the battery, the remote sensor LED indicator will light for 4 seconds, and then flash once per 70 second thereafter. Each time it flashes, the sensor is... - Page 8 transmitting data. You may go to Section 5 now to complete the GW1000 gateway configuration first to make its data displayed and resume the steps followed below. 4. Before install the sensor into its permanent location, we would suggest test the sensor in air, and see if moisture reading is 0.

Page 14: Custom Mode
7. Custom mode When in LIVE DATA display mode, you can calibrate the soil moisture sensor by enable the Custom mode. (Click More – Choose Calibration – Choose Soil Calibration – Tick the box on the left side of the Customize). - Page 18 Custom OFF: Moisture level is calculated based on default dry and wet definition: Dry (0%AD) AD: 70 Wet (100% AD) AD: 500 Soil Moisture = (moisture AD – 0%AD) * 100% / (100% AD – 0%AD ) Example: when sensor moisture AD is 310, calculated moisture is: (310 –...
- Page 19 inaccurate moisture level results. commonly happening with different soil type that gives very different output value at same moisture level condition. We introduced this custom mode to make this slope flexible so that it can match your soil type. This becomes a variable slope rate linear system.
- Page 20 When the displayed moisture readings are too low at extremely wet soil condition, you could decrease the 100%AD value to fix it. Please refer to the below example for better understanding. For example: When you use this product at the first time, you may turn off the custom mode and test the product at the following two situations: Situation One:...
- Page 21 value. Calculate the 100%AD value with the formula: Soil Moisture = (moisture AD – 0%AD) * 100% / (100% AD – 0%AD ) Now AD = 183 0%AD = 70 Target Soil Moisture Reading = 95% Then: 95% = (183 - 70)*100%/(100%AD – 70 ) Result: 100%AD = 188(take the Integer part) Then you can adjust the default 0%AD value to 188 and touch the screen for once to update...
- Page 22 Situation Two: Leave the sensor aside without touching any water, and the displayed moisture readings are much higher than 10% (e.g.40%). Solution: Enable the custom mode and adjust the 0%AD value. Calculate the 0%AD value with the formula: Soil Moisture = (moisture AD – 0%AD) * 100% / (500 –...
- Page 23 Result: 0%AD = 147(take the Integer part) Then you can adjust the default 0%AD value to 147 and touch the screen for once to update the data. When you get your expected moisture reading, click Save to save the setting. Note: The soil moisture sensor should be inserted totally into the soil for accurate result.
