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.
