ELECFREAKS Octopus Moisture Sensor (Analog Capacitive Soil)

ELECFREAKS Octopus Moisture Sensor (Analog Capacitive Soil) 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.

CHARACTERISTICS

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

SPECIFICATION

CONNECTION DIAGRAM

Connect the module with the wire(with buckle) to the PI pins on the Octopus:bit, and insert the micro:bit to the Octopus:bit.

PROGRAMMING

Program in the makecode and analog read P1 to get the value of soil moisture that would be showing on the micro:bit. Links

RESULTS

The value of the soil moisture is shown on the micro:bit.
