EASY plug Soil Moisture Sensor
The EASY Plug soil moisture sensor can read
the amount of moisture present in the soil
surrounding it. It's an ideal for monitoring an
urban garden, or your pet plant's water level.
This soil moisture 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).
If you use this sensor to make an automatic watering device, it will be
helpful to remind you to water your indoor plants or to monitor the soil
