Use a capacitive soil moisture sensor (it’s corrosion-resistant). If using a resistive type, power the sensor only during readings (use a transistor or MOSFET controlled by Arduino).

Confirm 5V supply is reaching the sensor. Replace the A0 pin connection with another analog pin and update it in code. Check if the sensor’s AOUT pin is functional.
