ELECFREAKS Octopus Soil Moisture Sensor module

This Soil Moisture Sensor module 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).

DESCRIPTION

Octopus Soil Moisture Sensor module can read the amount of moisture present in the soil surrounding it. It's a low-tech sensor, but ideal for monitoring an urban garden, or your pet plant's water level. This is a must-have tool for a connected garden!
This Soil Moisture Sensor module 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).
It will be helpful to remind you to water your indoor plants or to monitor the soil moisture in your garden. The Freaduino Sensor Shield is the perfect shield to connect this sensor to Arduino. Or Freaduino UNO which we had a pre-stray Octopus Brick interface.
