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.
Key Features
- Crash Switch Based – Reliable momentary contact detection with high sensitivity
- Digital Output – Simple HIGH/LOW signal for easy integration
- 3-Pin Interface – Standard GND, VCC, and Signal connections
- Compact Brick Format – Octopus series form factor for modular project builds
Ideal For
- Bump/collision detection on robots and vehicles
- Limit switches for mechanical projects
- Simple momentary input for micro:bit and Arduino projects
- STEM and classroom electronics activities
