Ecowitt WH51L Soil Moisture Sensor with LCD Display
The newest Ecowitt WH51L is a smart soil moisture sensor designed to give you accurate insights into your garden’s hydration. With its 1m (3.28ft) PVC probe cord, it can measure soil moisture at deeper levels (up to ~80cm), making it ideal for lawns, raised beds, and garden plots.
Key highlights:
Real-time data on screen – The built-in LCD display shows moisture readings instantly, unlike the WH51 model.
Deep & accurate monitoring – Longer cord allows you to track deeper root zone moisture with IP68 waterproof protection.
App & Wi-Fi connectivity – Pair with an Ecowitt Wi-Fi Gateway (sold separately) to view and track soil data on the Ecowitt app. Supports up to 8 sensors.
Console compatibility – Works with Ecowitt consoles (sold separately) for real-time viewing and internet upload of your sensor data.
Custom calibration – Easily fine-tune sensor readings for different soil types.
Good to know:
The WH51L shares channels with the WH51, but adds an LCD screen and deeper measurement ability. For best results, install the sensor body at least 20cm above the soil surface to avoid RF signal issues.
