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

Vibration sensor module alarm Motion sensor module vibration switch
SW-420 module based on the vibration sensor SW-420 and Comparator LM393
to detect if there is any vibration that beyond the threshold. The
threshold can adjust using an onboard potentiometer. When this no
vibration, this module output logic LOW the signal indicates LED light,
and vice versa.

If the module does not vibrate, the vibration switch was
closed on state, the output of low output, the green indicator light.
The product vibrates, vibration switches momentary disconnect, the
output is driven high, the green light does not shine.

The output can be directly connected to the microcontroller, which to
detect high and low level, so as to detect whether the environment
exists vibration, play a role in the alarm.

It is useful for a variety of shocks
triggering, theft alarm, smart car, an earthquake alarm, motorcycle
alarm. This module when compared with a normally open pneumatic shock
sensor module, shock triggered much longer can drive relay module the
use of the company’s production of SW-420 normally closed type
vibration sensors. comparator output signal clean wave well, driving
ability, 15mA rated voltage and 3.3V-5V output: digital switching output (0 and 1) a bolt-hole for easy installation small Board PCB dimensions: 3.2cm x 1.4cm. using the wide LM393 voltage comparator.

Note:

• Do not reverse the power directions, otherwise, it is possible to burn the chip
• Signal LED light is output Low, signal LED OFF output is High
• The output level close to the input voltage. 

Features :

1. Using SW-420 normally closed type vibration sensor
2. Comparator output, clean signal, good waveform, strong driving ability, >15mA
3. Using a wide voltage LM393 comparator
4. With bolt holes for easy installation
