Octopus Analog Capacitive Soil Moisture Sensor(EF04097)


Octopus Analog Capacitive Soil Moisture Sensor is the soil moisture electric brick in our Octopus series, the basic design is from the Octopus electric bricks and the setting of its outlook, the PCB fixing hole and the connectors are the same.

Adopted the capacitive sensing principle to detect the soil moisture, it perfectly avoids the problem of easy to be corroded of the resistive transducer and greatly extends its service time.

ELECFREAKS Octopus Moisture Sensor (Analog Capacitive Soil)


Hard to corrode. Support micro:bit in 3V.。 Easy and convenient for connection.


Name: Octopus Analog Capacitive Soil Moisture Sensor SKU:EF04097 Working Voltage: DC 3~5.5V Connection Mode: G-GND,V-VCC,S-signal pin Size: 19 x 76mm Net Weight: 5.5g

Dimensions and Outlook

Quick to Start

Hardware Connection
