5PCS SW-420 Vibration Sensor Module – Normally Closed Shock Detection Switch for Arduino, Smart Robot, and DIY Alarm Systems
5PCS SW-420 Vibration Sensor Module – Normally Closed Shock Detection Switch for Arduino, Smart Robot, and DIY Alarm Systems
The SW-420 Vibration Sensor Module (Normally Closed) is a sensitive vibration detection module ideal for creating motion-triggered alarms, anti-theft systems, and smart robotics. This pack of 5 modules uses a vibration switch that responds to sudden movements or shocks, outputting a digital signal that can be easily interpreted by Arduino, ESP32, Raspberry Pi, and other microcontroller boards
Perfect for DIY enthusiasts, this compact module can be integrated into smart vehicles, security alarms, and interactive robotics for detecting vibration-based activity or movement.
🔧 Key Features:
Vibration Detection: Detects mechanical vibrations or movement using a spring-type SW-420 sensor
Normally Closed Switch Type: Outputs a LOW signal when idle and a HIGH signal when vibration is detected
Digital Output (DO): Simple HIGH/LOW signal based on vibration events
Onboard Adjustable Sensitivity: Fine-tune detection sensitivity with the built-in potentiometer
Indicator LED: Visual feedback when vibration is detected
4-Pin Interface: VCC, GND, DO, and a redundant NC pin
Operating Voltage: 3.3V to 5V – suitable for most development platforms
Compact PCB Module: Easy to integrate into space-constrained projects
