Product Details

The Wireless Soil Moisture Sensor measures the volumetric water content (%VWC) of soil, reporting data in real time or storing it onboard the sensor's memory for long-term experiments. Durable and easy to use, the Wireless Soil Moisture Sensor is the perfect tool for monitoring controlled experiments in the classroom and long-term experiments outdoors. From experiments in evaporation and soil composition to water consumption and plant competition, the Wireless Soil Moisture Sensor makes it easy for students to investigate a wide array of topics both inside and outside of the classroom.

To use the sensor, dig a trench a few inches below the ground's surface and place the sensor's spear-shaped portion in the soil. Be sure to pack the soil tightly around the sensor for best accuracy. After use, the surrounding soil should be loosened to reduce the risk of damaging the sensor's cord.

Features
- Collect and display data in real time within PASCO Capstone or SPARKvue software
- Automate data collection for hours, days, or weeks with Logging Mode
- Bluetooth connectivity enables use in the classroom, lab, or field
- Supports use of GPS data from a mobile device for GIS mapping activities
- Selectable calibrations for predominantly sandy soils, clay soils, and loamy soils

Applications

  • Monitor soil moisture content to control irrigation in greenhouses and gardens
  • Measure changes in soil moisture over time due to evaporation and/or plant uptake
  • Investigate the effects of different land covers on soil moisture retention in xeriscaping
  • Determine the optimum soil moisture content required for plant species to germinate
  • Investigate the relationship between soil moisture content and heat stress in plants
  • Explore the effect of moisture on mold growth in food sources
  • Combine with GPS data from a mobile device and soil moisture data to an online map for GIS activities
