Detect movement and trigger alarms with the reliable SW-420 Vibration Sensor Module. This normally closed type vibration sensor is ideal for a wide range of applications, including:

• Vibration and theft alarms
• Intelligent car systems
• Earthquake detection
• Motorcycle security

Key Features:

• Normally Closed (NC) Operation: The vibration switch is closed (low level output) when no vibration is detected, and opens (high level output) when vibration occurs.
• Clear Digital Output: Provides a clean, digital switch output (0 and 1) for easy integration with microcontrollers like Arduino.
• Strong Driving Ability: The comparator output offers robust driving capability (> 15mA).
• Wide Voltage Compatibility: Operates seamlessly with a working voltage range of 3.3V to 5V.
• Easy Installation: Features a fixed bolt hole for secure and straightforward mounting.
• Compact Design: With a PCB size of 3.2 cm x 1.4 cm, it's perfect for projects where space is a consideration.
• LM393 Comparator: Utilizes the reliable LM393 wide voltage comparator for stable performance.

How it Works:

• No Vibration: The vibration switch remains closed, resulting in a low-level output, and the green LED is illuminated.
• Vibration Detected: The vibration switch opens, providing a high-level output, and the green LED turns off.

Connect the SW-420 directly to your microcontroller to easily detect vibration levels and trigger your desired effects or alarms.
