HW-390 Capacitive Soil Moisture Sensor Corrosion-Resistant for Arduino

The HW-390 Soil Moisture Sensor works by detecting the moisture capacity of the soil and not resistive as in other moisture sensors.
It is made of a corrosion resistant material giving it a long service life.
Insert it into soil and impress your friends with the real-time soil moisture data.
This module includes an on-board voltage regulator which gives it an operating voltage range of 3.3 ~ 5.5V.
This sensor is compatible with DFRobot 3-pin “Gravity” interface, which can be directly connected to the Gravity I/O expansion shield.
