PIR Motion Detection with Email Notification

Project 36:  PIR Motion Sensor

This project shows how to use a PIR motion detector 
that sends an email whenever motion is detected.





Hardware:
1 PIR Motion Sensor
1 Led (optional)
1 servo(optional)
1 speaker (optional)
connecting wires
breadboard
Ethernet Shield
Arduino R3 UNO board


Block Diagram:
Note: Although the sensor above is not a PIR but a Humidity and Temperature sensor
the schematic is still the same. (1=gnd, + = 5v,  S = ~)


Arduino Sketch:

  This sketch was automatically generated by Temboo software. 
  A step by step tutorial is available on their site.
  The sketch varies defending on your arduino and ethernet shields.

HEADER FILE:

IMPORTANT NOTE about TembooAccount.h

TembooAccount.h contains your Temboo account information and must be included
alongside your sketch. To do so, make a new tab in Arduino, call it TembooAccount.h,
and copy this content into it.

/*
Keeping your account information in a separate file means you can share the
main .ino file without worrying that you forgot to delete your credentials.

Challenges:

1. Add a blinking Led to indicate motion is detected.
2. Play a warning tone when motion is detected.
3. Use other types of sensors
4. Send yourself an hourly temperature/humidity reports via email.

Python Code:

/* You need to install Python on your PC.
 The example code is public domain */

import time
import serial
import smtplib

TO = 'putyour@email.here'
GMAIL_USER = 'putyour@email.here'
GMAIL_PASS = 'putyourpasswordhere'

SUBJECT = 'Intrusion!!'
TEXT = 'Your PIR sensor detected movement'

ser = serial.Serial('COM4', 9600)

def send_email():
    print("Sending Email")
    smtpserver = smtplib.SMTP("smtp.gmail.com",587)
    smtpserver.ehlo()
    smtpserver.starttls()
    smtpserver.ehlo
    smtpserver.login(GMAIL_USER, GMAIL_PASS)
    header = 'To:' + TO + '\n' + 'From: ' + GMAIL_USER
    header = header + '\n' + 'Subject:' + SUBJECT + '\n'
    print header
    msg = header + '\n' + TEXT + ' \n\n'
    smtpserver.sendmail(GMAIL_USER, TO, msg)
    smtpserver.close()
 
while True:
    message = ser.readline()
    print(message)
    if message[0] == 'M' :
        send_email()
    time.sleep(0.5)
