The Octopus Water Level Sensor detects water level using exposed parallel traces on the PCB. As the water level rises, more traces are submerged, producing a higher analogue signal output. Compatible with micro:bit (3 V) and other microcontrollers operating at 3–5.5 V.
Part of the ElecFreaks Octopus series, this sensor uses the standard 3-pin connector (GND, VCC, Signal) for easy plug-and-play connection with Octopus:bit and similar breakout boards.
Key Features
- Analogue Output – Signal proportional to water level for easy threshold detection
- 3-Pin Connection – GND, VCC, Signal for simple wiring
- micro:bit Compatible – Works at 3 V; read analogue values via MakeCode
- Compact – 59.15 × 19 mm, 5.5 g
Specifications
- Working Voltage: 3–5.5 V DC
- Connection: G (GND), V (VCC), S (Signal)
- Dimensions: 59.15 × 19 mm
- Weight: 5.5 g
Ideal For
- Water level monitoring and alarms
- micro:bit science projects
- Simple liquid level detection

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
