Vibration Sensor Module for Arduino Wiki - DFRobot

Introduction

Get this vibration sensor to build a burglar alarm system to protect your property. This cost-effective vibration sensor, characterized by high sensitivity, fast response and stable performance, is designed to detect vibration signals through its internal inductance coil. It supports 5~15V power supply and comes with digital signal output, adjustable sensitivity and onboard LED indicator for feeding back sensor status. When the vibration is detected, the sensor outputs Low and its indicator turns on. It can be connected with Arduino to make alarm system, vibration monitor, etc.

Specification

• Power Supply: 5-15V
• Output: switch quantity(output low)
• Output Current: ≤100mA(Max Load Current)
• Static Current: ≤6mA

int  OUT = 4;
int  i = 0;
void setup()
{
  Serial.begin(9600);
  pinMode(OUT, INPUT);
}
void loop()
{
   i = digitalRead (OUT);
   Serial.println(i);
   delay(5);
}

Expected Results

Read the IO3 status: when vibration detected, serial print 0, otherwise, serial print 1.
