Vibration sensor module alarm Motion sensor module vibration switch SW-420

Alarm for vibration sensor module In order to determine if there is any vibration that exceeds the threshold, the motion sensor module vibration switch SW-420 module uses the vibration sensor SW-420 and the comparator LM393. An inbuilt potentiometer can be used to change the threshold. This module’s output logic LOW signal signals LED light when there is no vibration, and vice versa.

In the event that the module is not vibrating, the green indicator light, low output, and vibration switch were all in the closed state. The product vibrates, causing a brief disconnect, driving the output to a high level and darkening the green light.

The microcontroller, which can detect high and low levels and determine whether vibrations are present in the environment, can be connected to the output and used to trigger an alarm.

Note:
It is important to remember that reversing the power directions could cause the chip to burn.
While the signal LED OFF output is high, the signal LED light output is low.
The output voltage in proximity to the input level.

Features: 

• Vibration sensor of the SW-420 usually closed kind.
• Comparator output: >15mA, robust driving capability, clean signal, nice waveform.
• LM393 broad voltage comparator is used.
• including bolt holes for simple assembly.
