Soil Moisture Measurement using Arduino

Soil Moisture Sensor can be used to detect water level on the soil, if the soil moisture is depleted it will send a signal to HIGH or give corresponding analog output. This sensor uses two probes to pass the current through the soil, and it reads resistance to get the moisture level, the more water into the soil the more soil conduct the electricity easily. Less resistance if the soil is dry.

The module uses a LM393 precision voltages comparator capable of single or split supply operation.
