Octopus Soil Moisture Sensor Brick
By using Octopus electronic bricks, you may connect Arduino/Freaduino compatible boards easily with various digital, analog and I2C/Uart interfaces. These the breadboard-less firm connection are prepared to extensive modules like poteniometers, sensors, relays, servos…even buttons, just plug and play.
Octopus Soil Moisture Sensor Brick 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 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).
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 senor to Arduino. Or Freaduino UNO which we had pre-stray Octopus Brick interface.
