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.
