This sensor uses the two probes to pass current through the soil, and then it reads that resistance to get the moisture level. More water makes the soil conduct electricity more easily (less resistance), while dry soil conducts electricity poorly (more resistance).


  • Power supply: 3.3v or 5v
  • Output voltage signal: 0~4.2v
  • Current: 35mA
