We're excited to announce that the Ecowitt WH52 is now available at Weather Spares. If you're serious about understanding what's happening beneath the surface of your garden, allotment, or growing beds, this sensor is a significant step up from a standard soil moisture probe.
What Is the Ecowitt WH52?
The WH52 is a wireless 3-in-1 soil sensor that measures three critical parameters in a single probe:
- Soil Moisture — volumetric water content (VWC) as a percentage, so you know exactly how wet or dry your soil is at root depth.
- Soil Temperature — essential for timing seed sowing, planting out, and understanding plant growth rates.
- Electrical Conductivity (EC) — a measure of dissolved salts and nutrients in the soil, giving you a direct indicator of soil fertility and fertiliser effectiveness.
That combination of moisture, temperature, and EC in a single wireless sensor is what sets the WH52 apart from the existing WH51 range.
Why EC Matters for Gardeners & Growers
Electrical conductivity is a metric more commonly associated with commercial horticulture and hydroponics, but it's increasingly relevant for home growers too. Here's why:
- Nutrient availability — EC gives you a proxy reading for how much dissolved fertiliser is present in the soil solution. Too low and your plants may be nutrient-deficient; too high and you risk root burn.
- Irrigation management — combining EC with moisture data helps you decide not just when to water, but what to add to the water.
- Soil health tracking — monitoring EC over time reveals how your soil is responding to compost additions, mulching, and feeding programmes.
How Does It Compare to the WH51?
The WH51 remains an excellent, cost-effective choice for straightforward soil moisture monitoring. The WH52 is the right choice if you want the additional insight of soil temperature and EC — particularly useful for vegetable growers, greenhouse operators, and anyone following a structured feeding programme.
