Arduino Soil Moisture Sensor [Hygrometer]
This sensor detects the moisture content in the soil using conductors located on two parallel rods and allows us to obtain this value.
Based on the value we receive, it enables us to confidently take the necessary actions.
We can connect the sensor to analog or digital pins, but my recommendation would be to connect and use it with analog pins.
As you know, analog pins take values between 0 - 1023, and this allows us to perform more precise operations.
