MP406 and MP306 ADR Standing Wave Technology Soil Moisture Sensors

The MP306/MP406 Soil Moisture Sensor is a robust, long term soil moisture measurement sensor that is unaffected by soil temperature or salinity, measuring volumetric soil water content using standing wave technology. It can be calibrated to provide accuracy within ±1%, and using the standard calibration curves ±3%.

Efficient irrigation scheduling and water management strategy require precisely measured soil water content.

Available in several configurations, and compatible with the ICT International IoT MFR Node, this sensor is suitable for deployment in both research and management projects:

  • MP406: bare ended sensor, voltage output.
  • MP306: bare ended sensor, voltage output; due to its needles arrangement is suitable for laboratory soil columns applications, or greenhouse pots.
  • MP406C-12V: 4-20mA sensor, 12V.
  • MP406C-24V: 4-20mA sensor, 24V.
  • SNiP-MP4 or SNiP-MP3: IoT connected MP406 or MP306.
