SW-420 Vibration Sensor Switch Module

The Vibration Sensor Switch Module SW-420 is designed to detect vibration beyond a certain threshold using the SW-420 vibration sensor and LM393 comparator. It features an onboard potentiometer for adjusting the sensitivity threshold. When there is no vibration, the module outputs a logic LOW signal, indicated by the LED light. Conversely, when vibration is detected, the module outputs a logic HIGH signal, turning off the LED.

The module can be connected to a microcontroller to detect high and low levels, allowing it to be used for vibration detection and alarm applications.

  Features:  

• Uses SW-420 normally closed type vibration sensor.
• Comparator output provides a clean signal with a good waveform and strong driving ability (>15mA).
• Utilizes a wide voltage range LM393 comparator.
• Includes bolt holes for easy installation.

  Specifications:  

• Operating Voltage: 3.3V to 5V DC
• Dimensions: 40mm x 15mm x 7mm (LxWxH)
• Weight: 3g

  Package Includes:  

1 x Vibration Sensor Switch Module SW-420

  Note:  

• Ensure correct polarity to avoid damaging the chip.
• The signal LED is off when the output is HIGH and on when the output is LOW.
• The output level is close to the input voltage.
