Key item features

  • ‌【Technology Principle】: The WH51 utilizes the advanced Frequency Domain Reflectometry (FDR) principle. The sensor probe generates a high-frequency electromagnetic field in the soil, precisely measuring the soil's dielectric constant by detecting changes in its capacitance (acting as a dielectric material). As soil moisture varies, so does the dielectric constant. The sensor directly and accurately converts this data into Volumetric Water Content percentage (%), providing a clear reflection of the soil's true moisture level. Scientific measurement ensures reliable results.
  • 【Rugged Outdoor Design】: Built for harsh outdoor conditions. The housing boasts an IP66 dustproof and waterproof rating, offering complete protection against dust ingress and powerful water jets. It consistently delivers stable performance under scorching sun, heavy rain, or dust, ensuring excellent durability.
  • 【Ultra-Long Battery Life】: Powered by a single AA battery. Thanks to ultra-low-power circuit design, the battery can last up to one year under standard usage, significantly reducing maintenance frequency and cost, making long-term monitoring worry-free.
  • 【Stable Wireless Connection】: Employing efficient RF technology and FSK modulation protocol, it achieves an optimal balance between power consumption and transmission range. In open areas, it ensures stable signal transmission over 100 meters with a standard gateway. When paired with a gateway featuring an enhanced antenna, the range can be extended to approximately 200 meters. Strong signal penetration and wide coverage.
  • 【Data & Application】: The WH51 is an independent sensor that requires an Ecowitt gateway (such as GW1100, GW1200) to access accurate data. After completing the Wi‑Fi setup, you can view real-time data on the WS View Plus app. The sensor is also fully compatible with other Ecowitt wireless sensors, including temperature, rainfall, solar radiation, and more, allowing you to build a complete personal weather and environmental monitoring system.
  • 【For Home Gardeners】: Monitor real-time soil moisture percentage, historical graphs, and trends via the Ecowitt App. Use data trends to guide optimal watering schedules, set custom humidity alerts, or enable fully automated irrigation by connecting with a smart water valve (sold separately).
  • 【For Agricultural & Research Users】: Supports professional manual calibration for different soil types within the App to meet high-precision monitoring requirements. An ideal tool for farmland irrigation management, landscape care, and soil research.
