The SW-18010P breakout module is a highly sensitive, non-directional vibration and shock sensor. It features a spring-and-pin mechanism that briefly closes the circuit when moved, making it ideal for anti-theft alarms, impact detection, and system wake-ups. Most modules operate at 3V to 5V and include an onboard comparator for clean digital signals.Pinout ConfigurationBreakout boards typically feature 3 or 4 pins:

• VCC: Connects to 3.3V or 5V
• GND: Connects to Ground
• DO (Digital Output): Sends a digital signal (High/Low) to your microcontroller
• AO (Analog Output): Provides a raw analog signal indicating vibration intensity (only available on 4-pin modules)

How it WorksInside the sensor’s black casing, a thin, flexible spring is wrapped around a central conductive pin.

• At Rest: The spring and pin do not touch, leaving the circuit open (normally open state).
• During Vibration: The spring wobbles and makes contact with the pin, momentarily closing the circuit.
• Onboard LED: When contact is made, the module’s green indicator light turns on, and the digital output (DO) temporarily drops to a logic low level.

Wiring & UsageYou can directly interface this sensor with a microcontroller like an Arduino.Wiring Steps:

1. Connect VCC to 5V on your microcontroller.
2. Connect GND to Ground.
3. Connect DO to a digital pin
