## Description

The Octopus Mercury Sensor is a tilt and angle detection module based on the mercury switch principle. When tilted, the mercury inside the switch makes or breaks contact, providing a simple way to detect orientation changes and object levelling. Part of the Octopus Electronic Bricks range from ElecFreaks, this module features a 3-pin interface for easy breadboard-less connection to Arduino and compatible boards. Key Features Mercury Switch Principle – Reliable tilt and angle detection using liquid mercury contact High Sensitivity – Fast response to orientation changes Simple Interface – 3-pin connector (Signal, VCC, GND) for plug-and-play use Analogue Output – Connects to any analogue input pin Long Life – Stable operation with durable mercury switch element Specifications Operating Voltage – 5 V Interface Type – Analogue Pin Definition – 1: Signal, 2: VCC, 3: GND Ideal For Tilt detection and orientation sensing Object levelling applications Angle measurement projects Arduino and microcontroller prototyping Warning: This module contains mercury. Handle with care and dispose of responsibly according to local regulations. Do not break open the sensor element.
