ECOWITT WH51L Soil Moisture Sensor with LCD Display and 1m PVC Wire Probe
For gardeners and plant enthusiasts who need to know exactly when their soil needs water, the ECOWITT WH51L soil moisture sensor takes the guesswork out of irrigation. Unlike basic sensors that only measure shallow moisture, this updated model features a 1m/3.28ft PVC wire probe that reaches deep into the soil—up to 80cm—so you can monitor moisture at the root zone where it matters most. The built-in LCD screen shows real-time moisture data right at the sensor, saving you from checking an app every time.
What sets the WH51L apart is its dual functionality: you can pair it with an ECOWITT Wi-Fi gateway (sold separately) to stream data to your phone via the Ecowitt app, or use a compatible display console for on-screen readings. The sensor sends alerts when soil is too dry or too wet, helping you avoid overwatering and root rot. Its IP68 waterproof probe withstands harsh outdoor conditions, and you can customize calibration for different soil types. Perfect for vegetable gardens, flower beds, or potted plants, the WH51L ensures your plants get the right amount of water every time.
