Vibration sensor SW-18020P

The Vibration sensor SW-18020P is a compact, non-directional spring-type switch for detecting movement, impact, or shaking. Operating as a normally open (NO) switch, it closes momentarily when vibrations exceed a threshold, providing a simple digital on/off output. Its robust design ensures reliable performance in demanding environments, while its small 4.5mm × 10mm footprint allows easy integration into space-constrained projects.
 
The sensor requires minimal circuitry, just a pull-up or pull-down resistor for stable operation, and responds quickly to low-frequency vibrations. Its sealed construction protects against dust and moisture, making it a durable, low-cost alternative to more complex accelerometers.
 
Ideal for tamper detection, anti-theft alarms, smart home devices, or motion-activated features, the SW-18020P is compatible with all standard microcontrollers, including Arduino and Raspberry Pi. Integrate it on breadboards or PCBs easily, and consider using a Qwiic adapter for simplified wiring. Add this reliable vibration sensor to your next project for accurate, cost-effective motion detection.
