## Description

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. Warning: The components above the MAX water level line are not waterproof. Do not submerge the sensor beyond the marked line. 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 Resources MakeCode Example Program
