Soil Moisture Sensor Earth

Soil Moisture Sensor Earth

The Soil Moisture Sensor was developed to detect variations in soil moisture, and when the soil is dry the sensor output is in a high state and when it is wet it is in a low state.

The limit between dry and wet can be adjusted using the potentiometer on the v, which will regulate the digital output D0. However, to have a better resolution it is possible to use the A0 analog output and connect to an AD converter, which is present in the Arduino, for example.

NOTE: Product susceptible to oxidation, so it is recommended only for project prototyping and not recommended for professional applications or final products.
