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.

- 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
Jargon buster
Plain-language definitions for the technical terms used above.
- GND
- GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- VCC
- VCC is the positive power-supply connection on a chip or module. Connecting it to the correct supply voltage is needed for the part to power on and helps avoid damaging the electronics.
