Vibration Sensor-Vibration switch HDX-2 SW-420 Normally Closed Highly Sensitive

The SW-420 Normally Closed Vibration Sensor, also known as a Vibration Switch, is an electronic component used to detect and measure vibrations. Here's some information about this sensor:

Normally Closed (NC):
   The SW-420 Vibration Sensor is of the Normally Closed type, which means that the circuit is closed by default when there is no vibration. When the sensor detects vibration or movement, it opens the circuit, breaking the connection.

Vibration Detection:
   The SW-420 sensor is specifically designed to detect vibrations. It contains a small metal ball or spring inside that moves when subjected to vibrations. When the ball or spring moves, it triggers a change in the sensor's electrical output.

Functionality:
   The vibration sensor acts as a switch, providing a digital output. When the sensor detects vibration, it opens the circuit and interrupts the flow of current. This change in the circuit can be used to trigger an action, such as activating an alarm, turning on a device, or signaling an event.

Applications:
   The SW-420 Vibration Sensor is commonly used in various applications, including:

   - Security systems: Detecting unauthorized movement or tampering.
   - Impact detection: Triggering an action when an impact occurs.
   - Industrial equipment: Monitoring vibrations in machinery to detect faults or maintenance needs.
   - Home automation: Activating devices or triggering events based on vibrations.
   - Robotics: Sensing external impacts or movements.

It's important to note that the SW-420 Vibration Sensor is a basic vibration detection component, and additional circuitry or microcontrollers may be required to process the sensor's output and control other devices or systems based on the detected vibrations.

Features:

• Type: normally closed
• Working voltage: 3.3V to 5V
• Compact size

Package Contents:
