Soil Moisture Sensor

This module is a simple way to detect if your plants need watering. These are slightly different to the Water Sensor as it allows for sensitivity adjustment.  

Simply connect the sensor to the sensitivity control board, add power wires and the sensor to an input pin, and away you go! 

You can also use these for a variety of other applications, such as detecting wet hands, rainfall, or if someone has stepped out of the shower.
