This analog capacitive soil moisture sensor measures soil moisture levels by capacitive sensing, rather than resistive sensing like other types of moisture sensor
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 3-pin "Gravity" interface, which can be directly connected to the Gravity I/O expansion shield
