The soil moisture sensor uses two probes to easily measure the current flow through soil. The moisture level can be sensed by measuring the resistance of the soil.  If the soil has more water in it, it will conduct the electricity more easily (less resistance), while dry soil will hardly conduct the electricity (more resistance).

The soil moisture sensor will help you to determine the water content of your indoor flower pots and monitor the soil moisture in your garden.
