SHT45-AD1F

±1.0% RH Digitaler Feuchtesensor / Filtermembran

Als Teil von Sensirions industrieerprobten Feuchte- und Temperatursensoren bietet der SHT45-AD1F das beste Preis-Leistungs-Verhältnis auf dem Markt. Durch die Tape-and-Reel-Verpackung und der SMD-Fähigkeit ist der SHT45-AD1F ideal für hochvolumige Anwendungen.

Der SHT45-AD1F baut auf einem völlig neuen und optimierten CMOSens®-Chip auf, der einen reduzierten Stromverbrauch und weiter verbesserte Genauigkeitsspezifikationen bietet. Mit dem erweiterten Versorgungsspannungsbereich von 1.08 V bis 3.6 V ist der Sensor die perfekte Lösung für mobile und batteriebetriebene Anwendungen. Die integrierte SHT45-AD1F PTFE-Membran bietet zusätzlichen Schutz vor Partikeln und ermöglicht den Betrieb des Sensors unter rauen Bedingungen. Zudem entspricht der SHT45-AD1F den relevanten Standards für gesundes Bauen RESET® und WELL Building Standard™.
