Basic tutorial of how to setup a SW-420 Vibration sensor with the Raspberry Pi.

PARTS:
RPI 3 – https://amzn.to/2VA9pQY
4 Amp Power Adapter – https://amzn.to/2CTptWu
16GB micro SD – https://amzn.to/2SFMwd3
120 pcs jumper cable: https://ebay.to/2VAb9cY
Vibration Sensors: https://amzn.to/2AzL0lC

SCHEMATIC:

CODE:

#!/usr/bin/python
import RPi.GPIO as GPIO
import time

#GPIO SETUP
channel = 17
GPIO.setmode(GPIO.BCM)
GPIO.setup(channel, GPIO.IN)

def callback(channel):
        if GPIO.input(channel):
                print "Movement Detected!"
        else:
                print "Movement Detected!"

GPIO.add_event_detect(channel, GPIO.BOTH, bouncetime=300)  # let us know when the pin goes HIGH or LOW
GPIO.add_event_callback(channel, callback)  # assign function to GPIO PIN, Run function on change

# infinite loop
while True:
        time.sleep(1)
