Psychrometer Soil Moisture Sensor

A psychrometer soil moisture sensor is a device designed to measure the amount of moisture present in soil. It operates on the principle of psychrometry, which involves employing two thermometers to assess and compare the humidity levels surrounding each thermometer. The sensor comprises two wicks: a dry wick that acts as a reference point, and a wet wick. When air is passed through the sensor, the wet wick evaporates a certain amount of water which in turn cools the thermometer in contact, resulting in a lower temperature reading. The difference in temperature between the dry and wet wicks provides an indication of the moisture content within the soil.

Applications of Psychrometer Soil Moisture Sensors

  • Agriculture: Precision irrigation, efficient water management
  • Environmental Monitoring: Soil health assessments, water conservation
  • Geotechnical Engineering: Slope stability, landslide prevention
