Impact Collision Switch Sensor Module For Arduino

Impact Collision Switch Sensor Module For Arduino is a simple digital sensor module designed to detect physical impacts, vibrations, or collisions using a lever-type microswitch. Its compact PCB form factor and standard 3-pin interface make it easy to integrate into Arduino and other microcontroller projects for event detection or tamper monitoring.

Key Features:

• Collision Detection: Senses physical impact, vibration, or collision with high reliability.
• Digital Output: Provides clear HIGH/LOW signal for microcontroller input.
• Onboard Indicator LED: Visual indication of switch activation state.
• Plug-and-Play Interface: Standard 3-pin header for easy connection.
• Compact Design: Minimal PCB footprint fits tight enclosures.

Technical Specifications:

• Operating Voltage: 3.3V to 5V DC
• Output Signal: Digital (LOW on impact)
• Switch Rating: 2A at 125V AC (microswitch rating)
• Trigger Type: Normally open lever switch
• Module Model: KY-031 or YL-99 (varies by manufacturer)
