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.\u003c\/p\u003e\n\u003cp\u003eTo 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.\u003c\/p\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-12 mb-2\"\u003e\n\u003ch3 class=\"h2\"\u003eFeatures\u003c\/h3\u003e\n\u003cul class=\"condensed multi-col\"\u003e\n\u003cli\u003eCollect and display data in real time within PASCO Capstone or SPARKvue software\u003c\/li\u003e\n\u003cli\u003eAutomate data collection for hours, days, or weeks with Logging Mode\u003c\/li\u003e\n\u003cli\u003eBluetooth connectivity enables use in the classroom, lab, or field\u003c\/li\u003e\n\u003cli\u003eSupports use of GPS data from a mobile device for GIS mapping activities\u003c\/li\u003e\n\u003cli\u003eSelectable calibrations for predominantly sandy soils, clay soils, and loamy soils\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"col-12 mb-2\"\u003e\n\u003ch3 class=\"h2\"\u003eApplications\u003c\/h3\u003e\n\u003cul class=\"condensed multi-col\"\u003e\n\u003cli\u003eMonitor soil moisture content to control irrigation in greenhouses and gardens\u003c\/li\u003e\n\u003cli\u003eMeasure changes in soil moisture over time due to evaporation and\/or plant uptake\u003c\/li\u003e\n\u003cli\u003eInvestigate the effects of different land covers on soil moisture retention in xeriscaping\u003c\/li\u003e\n\u003cli\u003eDetermine the optimum soil moisture content required for plant species to germinate\u003c\/li\u003e\n\u003cli\u003eInvestigate the relationship between soil moisture content and heat stress in plants\u003c\/li\u003e\n\u003cli\u003eExplore the effect of moisture on mold growth in food sources\u003c\/li\u003e\n\u003cli\u003eCombine with GPS data from a mobile device and soil moisture data to an online map for GIS activities\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch3 class=\"h2\"\u003eHow It Works\u003c\/h3\u003e\n\u003cp\u003eThe Wireless Soil Moisture Sensor determines the percent water content by volume of soil by measuring the dielectric constant of the space around the blade-shaped capacitor. An electric field generated by the sensor responds to the capacitance of the surrounding space and uses the response to calculate the soil's percent water content per volume.\u003c\/p\u003e\n\u003cp\u003eLiquid water has a uniquely high capacitance, making it the predominant contributor to the sensor's measurement. The sensor comes factory-calibrated for soils with discreet values of volumetric water content and outputs readings in percentage of total space filled. Accurate readings range from 0%, in which there is little to no moisture in a dried sample, to 45%, in which all the available pore space within the soil is saturated with water. For a % saturation reading, divide the value by 45.\u003c\/p\u003e\n\u003cp\u003eThe sensor has been calibrated to support analyses in 3 of the predominant soil types: sandy soils, clay soils, and loamy soils.
