DFROBOT Gravity: Analog Capacitive Soil Moisture Sensor- Corrosion Resistant
This analog capacitive soil moisture sensor measures soil moisture levels by capacitive sensing, rather than resistive sensing like other types of moisture sensor
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. Download User Guide on this page for more. (Technical Specification - User Guide)
INTRODUCTION This product measures soil mositure levels by capacitive sensing, rather than resistive sensing like other types of moisture sensor. It is made of a corrosion resistant materal giving it a long service life. Insert it into soil and impress your friends with the real-time soil moisture data!
The product includes an on-board voltage regulator which gives it an operating voltage range of 3.3 ~ 5.5V. It is compatible with low-voltage MCUs (both 3.3V and 5V logic). To make it compatible with a Raspberry Pi, an ADC converter is required.
This sensor is compatible with our 3-pin "Gravity" interface, which means it can be directly connected to the Gravity I/O Expansion Shield.
