ECOWITT WH51L Soil Moisture Sensor with 1m/3.28ft PVC Wire Probe, LCD Display, Needs to Pair with Wi-Fi Gateway, 915 MHz

Does what it says it does and is great for deeper readings!Highly tecommend.

This is the only water meter I have found with consistent repeatable results. It does test at 0% in air and 100% in a glass of water, but for my soil it shows about 22% when dry and about 37% when fully wet so for my dirt it is a narrow range.

No more guess work A+

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.

100% recommend.
