Anwendungsfall	Empfehlung
Einfache Gartenbewässerung, Einsteiger	SMT50
Präzisionslandwirtschaft, Forschung, mehrere Sensoren	SMT100
Wie SMT100, aber platzsparend (Säulenversuche, Bautechnik)	SMT100 Pro
Rasenflächen, Sportplätze, Golfplatz – großes Messvolumen	AquaFlex
Lufttemperatur und -feuchte (Gewächshaus, Klimamonitoring)	TH100
Bodentemperaturprofil, Tiefenmessung	T100

? Tipp: Für den Betrieb mit OpenSprinkler benötigen Sie je nach Sensor entweder denRS485 adapter for OpenSprinkler (für RS485-Sensoren)
oder das Analog sensor board (für SMT50 und SMT100 Analog-Variante).
