The Collision Switch Module is a compact and reliable sensor designed to detect physical contact or collisions in a variety of electronic projects. When pressure is applied or an object makes contact with the built-in spring switch, the module outputs a digital signal, making it ideal for applications that require touch or impact detection.
Whether you're building interactive robots, obstacle-avoiding vehicles, or smart alarm systems, this module provides a simple yet effective way to sense collisions or bumps. It interfaces easily with microcontrollers like Arduino, Raspberry Pi, and other development platforms.
Key Features:
-
Simple Collision Detection:Detects mechanical impact through a spring-based switch mechanism.
-
Digital Output:Provides a high or low signal based on collision status, easy to interface with microcontrollers.
-
Compact Design:Small form factor ideal for embedded applications and robotic systems.
-
Plug-and-Play:Equipped with standard 3-pin interface for easy wiring.
-
LED Indicator:Built-in LED shows module activity when collision is detected (in some versions).
-
Durable Build:Mechanical switch designed for repeated usage with consistent performance.
Applications:
-
Obstacle detection in robotics
-
Collision sensing in autonomous vehicles
-
Touch/impact-activated switches
-
Anti-theft or bump-sensitive alarm systems
-
Interactive projects and DIY electronics
-
Game controllers and physical input devices
