  • Page 2: Introduction

    1. Introduction Thanks for purchasing this WN51E soil moisture sensor. This device measures soil moisture. The data can be streamed by GW1000 Wi-Fi Gateway (sold separately) and can be viewed on our WS View mobile application after the Wi-Fi configuration done.

  • Page 4: Features

    3.1 Features Soil Moisture Sensor  Measures soil moisture content every 71 seconds.  Sensor covered with ceramics for more accurate measurement.  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.
  • Page 5 When paired with a GW1000 Wi-Fi Gateway:  Monitor live sensor data on the Live Data page of the WS View app (requires the gateway and your phone is using the same Wi-Fi network)  Up to 8 channels supported. Channel names can be edited on the app.
  • Page 6 Remote monitoring with smart phone, laptop, or computer by visiting the website Note: The WH51 and WN51E 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.

    (sold separately). 5.1 Pair with Gateway If GW1000 has been in operation, and you have never had any WN51E soil moisture sensor setup before, just power up the sensor and GW1000 will pick soil moisture data automatically. Please make sure your setup on...

    3. Click Re-register on the Sensor ID page. Then the new sensor will be learned and the old sensor will be erased. 5.2 Wi-Fi Connection for the Gateway For this part, please refer to the manual of the GW1000 Wi-Fi gateway. Any question, please contact the customer service.
  • Page 13 WS View app. To remote monitor the sensor data, please upload the data to our free Ecowitt Weather Server: https://www.ecowitt.net. Detailed operation instructions can be found on the GW1000 manual.
  • 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 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. Adjusting principle: 0%AD is used to adjust for dry condition reading inconsistency.
  • Page 20 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: Place the sensor into a glass of fresh water, and the displayed moisture readings is much...
  • Page 21 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 the data.
  • Page 22 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 – 0%AD ) Now AD = 183 100%AD = 500 Target Soil Moisture Reading = 10%...
  • Page 23 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.
