Vibration Sensor Module

Vibration Sensor Module
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, and the green indicator light. The product vibrates, vibration switches momentary disconnect, the output is driven high, and the green light does not shine.
The output can be directly connected to the microcontroller, which detects high and low levels, 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 alarms, smart cars, an earthquake alarms, and 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.
