Description
Note: The WH52 sensor requires a gateway or console for data display.
- Multi-Parameter Measurement:
Measures soil moisture, soil temperature, and electrical conductivity (EC). - Soil Temperature Sensor:
High-precision NTC thermistor closely contacts soil particles to capture the temperature actually perceived by roots. - Soil Electrical Conductivity Sensor:
Dual-electrode measurement determines total soluble salts in soil solution (μS/cm). - Data Transmission & Channel Sharing:
Sends data every 70 seconds to a gateway or console; shares 16 soil moisture channels with WH51/WH51L (8 channels for HP350x, WN1900/1920). - Connectivity & Remote Access:
Once paired with a gateway, historical data and alerts for abnormal conditions can be viewed via the ecowitt App or ecowitt.net; supports data upload to Ecowitt, WU, WOW, or a custom server. - Compact & Durable: IP66-rated for outdoor use; plug-and-play design.
- Power Management: Powered by 1 AA battery (not included) with low-power design; each device has a unique Sensor ID for easy registration and management in the ecowitt App.
Compatible gateways / consoles (Wi-Fi and/or Cellular): GW1200/GW2000/GW3000/HP2550/HP2560/WS3800/WS3820/WS3900/WS3910/WN1920/WN1980/WN1820/WN1821/WN1700
Note:
1. The sensor may share the same channels with other sensors of the same type.
2. Some data is cloud-only and not available on compatible consoles.
3. Compatibility may change with product updates. Please refer to the latest compatibility table(at the bottom of the product page) or contact us for confirmation.
Please refer to the table to choose correct additional sensors and consoles before checkout.
