The Octopus Crash Sensor Brick is a simple collision detection module based on a momentary crash switch. When physical contact is made, the switch triggers a digital signal — making it ideal for bump detection in robotics, limit switches in CNC or 3D printer projects, and basic button input.

Part of the ElecFreaks Octopus series of modular sensor bricks, it features a standard 3-pin interface for easy connection to micro:bit, Arduino, and other microcontroller platforms.
