SEN-MOISTURE Arduino - Moisture sensor for soil moisture

The Soil Moisture Sensor with its two long probes offers an optimal result and is ideal for e.g. an automatic irrigation system. The two large exposed pads act as probes for the sensor and serve as a variable resistor. The more water there is in the soil, the better the conductivity between the pads, this leads to a lower resistance and a higher voltage at the output.
