Arduino Soil Moisture Sensor

This video tutorial explains how to use a resistive soil moisture sensor with an Arduino. It covers the sensor's functionality, wiring, and coding using Tinkercad. The tutorial also discusses powering the sensor intermittently to prevent probe oxidation and using LEDs to indicate soil moisture levels. Calibration and practical applications are highlighted for effective sensor use.
