This analog capacitive soil moisture sensor measures soil moisture levels by capacitive detection, rather than by resistive detection like other types of moisture sensors.
It is made of a corrosion-resistant material, which gives it a long service life.
Insert it into the ground and get real-time soil moisture data.
This module includes a voltage regulator that allows 3.3 ~ 5.5V operation.
