Low-cost electromagnetic sensors are increasingly being used to characterize the spatio-temporal dynamics of soil water content, despite the reduced accuracy of such sensors as compared to reference electromagnetic soil water content sensing methods such as time domain reflectometry. Here, we present an effective calibration method to improve the measurement accuracy of low-cost soil water content sensors taking the recently developed SMT100 sensor (Truebner GmbH, Neustadt, Germany) as an example. We calibrated the sensor output of more than 700 SMT100 sensors to permittivity using a standard procedure based on five reference media with a known apparent dielectric permittivity (1 < Ka < 34.8). Our results showed that a sensor-specific calibration improved the accuracy of the calibration compared to single “universal” calibration. The associated additional effort in calibrating each sensor individually is relaxed by a dedicated calibration setup that enables the calibration of large numbers of sensors in limited time while minimizing errors in the calibration process 000827239 536__ $$0G:(DE-HGF)POF3-255$$a255 - Terrestrial Systems: From Observation to Prediction (POF3-255)$$cPOF3-255$$fPOF III$$x0 000827239 588__ $$aDataset connected to CrossRef 000827239 7001_ $$0P:(DE-Juel1)129472$$aHuisman, Johan Alexander$$b1$$ufzj 000827239 7001_ $$0P:(DE-Juel1)140127$$aSchilling, Bernd$$b2$$ufzj 000827239 7001_ $$0P:(DE-Juel1)129555$$aWeuthen, Ansgar$$b3$$ufzj 000827239 7001_ $$0P:(DE-Juel1)129549$$aVereecken, Harry$$b4$$ufzj 000827239 773__ $$0PERI:(DE-600)2052857-7$$a10.3390/s17010208$$gVol. 17, no. 1, p. 208 -$$n1$$p208$$tSensors$$v17$$x1424-8220$$y2017 000827239 8564_ $$uhttps://juser.fz-juelich.de/record/827239/files/sensors-17-00208-v2.pdf$$yOpenAccess 000827239 8564_ $$uhttps://juser.fz-juelich.de/record/827239/files/sensors-17-00208-v2.gif?subformat=icon$$xicon$$yOpenAccess 000827239 8564_ $$uhttps://juser.fz-juelich.de/record/827239/files/sensors-17-00208-v2.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000827239 8564_ $$uhttps://juser.fz-juelich.de/record/827239/files/sensors-17-00208-v2.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000827239 8564_ $$uhttps://juser.fz-juelich.de/record/827239/files/sensors-17-00208-v2.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000827239 8564_ $$uhttps://juser.fz-juelich.de/record/827239/files/sensors-17-00208-v2.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000827239 8767_ $$8sensors-166623$$92017-01-16$$d2017-01-17$$eAPC$$jZahlung erfolgt$$zCHF 1480,- 000827239 909CO $$ooai:juser.fz-juelich.de:827239$$popenCost$$pVDB$$pVDB:Earth_Environment$$pdriver$$pOpenAPC$$popen_access$$popenaire$$pdnbdelivery 000827239 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129440$$aForschungszentrum Jülich$$b0$$kFZJ 000827239 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129472$$aForschungszentrum Jülich$$b1$$kFZJ 000827239 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)140127$$aForschungszentrum Jülich$$b2$$kFZJ 000827239 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129555$$aForschungszentrum Jülich$$b3$$kFZJ 000827239 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129549$$aForschungszentrum Jülich$$b4$$kFZJ 000827239 9131_ $$0G:(DE-HGF)POF3-255$$1G:(DE-HGF)POF3-250$$2G:(DE-HGF)POF3-200$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bErde und Umwelt$$lTerrestrische Umwelt$$vTerrestrial Systems: From Observation to Prediction$$x0 000827239 9141_ $$y2017 000827239 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000827239 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 000827239 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search 000827239 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bSENSORS-BASEL : 2015 000827239 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal 000827239 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ 000827239 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000827239 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000827239 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000827239 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000827239 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC 000827239 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000827239 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000827239 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000827239 920__ $$lyes 000827239 9201_ $$0I:(DE-Juel1)IBG-3-20101118$$kIBG-3$$lAgrosphäre$$x0 000827239 980__ $$ajournal 000827239 980__ $$aVDB 000827239 980__ $$aUNRESTRICTED 000827239 980__ $$aI:(DE-Juel1)IBG-3-20101118 000827239 9801_ $$aFullTexts 000827239 980__ $$aAPC
