## Description

desertcart.com: ECOWITT WH51L Soil Moisture Sensor with 1m/3.28ft PVC Wire Probe, LCD Display, Needs to Pair with Wi-Fi Gateway, 915 MHz : Patio, Lawn & Garden

Review: Easy, quick set-up and great operation - I just installed an ECOWITT system to monitor the soil moisture in our yard. While we recently were on an extended vacation, both front and rear drip irrigation systems stopped, and we nearly lost several mature palm trees and other plants in our beautifully landscaped yard. I purchased the Ecowitt GW3000 Wi-Fi & Ethernet Weather Station Gateway and two ECOWITT WH51L Soil Moisture Sensors; one for the front yard and backyard. This system was by far the easiest home automation devices/system that I have installed and worked with across an extensive set of devices and systems throughout our home and yard. It simply was “plug and play” with very good instructions. The Gateway was easy to link to my Wi-Fi and the sensors were automatically added as I powered them up. Everything was in great working order right out of the box. You test the sensors in the ambient air and then a glass of water to make sure that they are reading and transmitting correctly. I wasn’t sure what the range would be since I was placing the two sensors at a diagonal across the yard with the gateway inside the house. Each one is approximately 40 ft. from the gateway and has no connection. I’m powering the sensors using Procell Alkaline Intense Power AA, 1.5V Batteries which are designed for high drain professional devices (like my door locking systems). The sensor is not a high drain device, just trying to get the longest operational duration per battery. If necessary, I would try Lithium batteries next (different voltage drop curve than alkaline batteries). Since I’m not looking for exact soil moisture measurement, I can’t speak to the accuracy. It was 0% in the air and 100% in the water. Current readings are 46% and 21% giving me a baseline to work from when programming the sprinkler systems. I’m super happy with the value for my money. The entire system is far, far less that me having to replace one tree or major planting due to lack of water.
Review: Works great for young fruit trees and is accurate - I have deployed a few of these with my new bare root fruit trees to get a more accurate measure of moisture content at the depth that matters for the trees. It was easy to setup and the probe seems well made. The display is nice, but I use the app much more often. One hint, if you need to find the sensor ID look inside the battery compartment. So far these have worked perfectly, consistently sending data back and I did check calibration and it is consistent.

## Features

- 【ECOWITT 2024 Newest Soil Moisture Meter】Ecowitt WH51L soil moisture sensor with 1m/3.28ft PVC sensor wire could measure soil moisture. The LCD screen could display the real-time data. The data can be streamed by Ecowitt Wi-Fi Gateway (sold separately) and they can be viewed on the Ecowitt APP after the Wi-Fi configuration is done. A display console(sold separately) also can be used to display the received sensor value and submit it to the Internet.
- 【Difference between WH51 and WH51L】Both of them are designed to measure soil moisture. However, WH51L with an LCD screen could display the real-time data while WH51 does not. Besides, the 1m/3.28ft PVC cord of WH51L enables you to measure deeper soil moisture up to almost 80cm while WH51 can measure shallow soil moisture. What's more, the sensor probe of WH51L's waterproof lever is up to IP68 while WH51 is IP66.
- 【When Pairing with Ecowitt Gateway】: The Ecowitt gateway(sold separately), such as GW1100/GW2000/GW1200, supports up to 8 channels of WH51L soil moisture sensors and displays the data on Ecowitt app after WI-Fi configuration. Channel names can be edited on the app.
- 【When Pairing with Ecowitt Consoles】: When pairing with a display console(sold separately), such as HP2550/HP2560/HP3500/WN1820/WN1821, up to 8 channels of WH51L sensors are supported and you can view soil moisture data in real-time on the Display and the console will upload the data to the Internet. Other consoles, such as WN1900/WN1910/WN1980/WN1920/WS3800/WS3900/WS6006, could be a gateway to pair with the WH51L but NOT display the data on the screen. When paired with WH0291, you only can view soil moisture data in real-time on the Display, and the WH0291 could NOT upload the data to the Internet.
- 【Custom Mode】: When the WH51L sensor is inside soil with different humidity levels, it will generate electrical signals of different intensities. The sensor will convert the electrical signals into AD values. The higher the humidity, the greater the AD value. Please refer to the user manual to get the details about how to calibrate the WH51L.
- 【Note Before Purchase】: WH51L and WH51 share the same 8 channels of Soil on the Ecowitt system. When placing the WH51L, it is highly recommended that the WH51L's body had better be placed at least 20cm higher than the surface of the soil. If the device's body is very close to the surface, RF would decline, which might affect the transmission of the data.

### ⭐⭐⭐⭐⭐ Works well, Excellent Wi-Fi Transmission
*by A***R on August 22, 2025*

I purchased this version with the longer wire and LCD Screen as I was having WIFI reception problems with my Ambient in-ground soil moisture sensor. I felt that getting the transmitter two to three feet off the ground would enhance my transmission / reception. This along with the antenna on the Ecowitt GW3000 solved all my reception problems. In short, the extra expense was a good choice. Installation of the sensor was straight forward. My only less than favorable comment is that I wish the sensor housing were some other color than stark white. Black, brownish or green would be preferable for my use.
