SW-420 Vibration Sensor Module Alarm for Arduino - Digital Output
The SW-420 Vibration Sensor Module is a digital switch-type sensor designed for Arduino, Raspberry Pi, and other 3.3V/5V microcontroller platforms. It detects shocks and vibrations via an SW-420 normally-closed sensor element, providing a clean TTL-level output signal through an onboard LM393 comparator.
Features
- Digital vibration switch based on SW-420 sensor and LM393 comparator.
- Adjustable sensitivity via onboard potentiometer for precise threshold setting.
- Wide operating voltage range from 3.3V to 5V DC for flexible system integration.
- Strong output drive capability (>15mA) for direct interfacing with microcontrollers.
- Includes mounting holes for secure and stable physical installation.

This module integrates a sensitive SW-420 vibration switch, which is a normally-closed (NC) mechanical sensor, with a precise LM393 voltage comparator. The comparator converts the sensor’s mechanical state change into a clean digital signal, eliminating noise and providing a reliable TTL-compatible output. The output is logic LOW (LED illuminated) in a static, non-vibrating state and switches to logic HIGH (LED off) upon detecting a vibration event that exceeds the user-adjustable threshold.
Designed for robustness in embedded control systems, the module operates across a standard 3.3V to 5V logic range, making it compatible with Arduino, ESP32, STM32, and other common development boards. Its compact form factor and pre-drilled mounting holes facilitate easy integration into prototypes, alarm systems, and industrial monitoring setups.
