Capacitive Analog Soil Moisture Sensor, 3.3~5.5V Corrosion Resistant with Gravity 3-Pin interface for Raspberry
DFRobot 100% Capacitive Soil Moisture Sensor, 3.3 ~ 5.5V outpu Severity 3-Pin interface compatible with Arduino Analog Corrosion Resistant for Garden Plants / Humidity Detection / Intelligent Agriculture
This product measures the levels of soil mositure by capacitive sensors, rather than detection as other types of resistive moisture sensor. it is made from corrosion resistant materal giving it a long life. insert it in the soil and impress your friends with real-time soil moisture data!
The product includes an on-board voltage regulator that gives it a 3.3 ~ 5.5V operating voltage range. 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 connected directly to the Gravity I / O expansion shield.
the following image shows an example of the project-a device that tells you when the plant needs watering.
