Security System - PIR Motion, PiCamera, GMail

[chelseymh]

Hi!

I am trying to simply set up a security system. I have the PIR motion sensor and Pi Camera working fine. But it does not send an email (I've followed countless online tutorials - so, I have mpack and all the other email requirements installed) (Gmail is allowing insecure apps too). It shows no errors when running my program.

Here is my script:

Code: Select all

import RPi.GPIO as GPIO
from gpiozero import MotionSensor
from picamera import PiCamera
from datetime import datetime
from email.mime.multipart import MIMEMultipart
from email.mime.base import MIMEBase
from email.mime.text import MIMEText
import email.encoders
import smtplib
import os
import email
import sys
import time

camera = PiCamera()
jpg_image = ".jpg"
camera.rotation = 180 # delete or adjust to 90, 180, or 270 accordingly
GPIO.setmode(GPIO.BOARD)
GPIO.setwarnings(False)

GPIO.setup(11, GPIO.IN)         #Read output from PIR motion sensor
GPIO.setup(3, GPIO.OUT)         #LED output pin

fromaddr = "EMAIL"
toaddr = "EMAIL"

# prepare the email
f_time = datetime.now().strftime("%A %B %d %Y @ %H:%M:%S")
msg = MIMEMultipart()
msg["Subject"] = f_time
msg["From"] = fromaddr
msg["To"] = toaddr
text = MIMEText("WARNING! Motion Detected!")
msg.attach(text)

while True:
       i=GPIO.input(11)
       if i==0:                 #When output from motion sensor is LOW
            GPIO.output(3, 0)  #Turn OFF LED
            time.sleep(0.1)
       elif i==1:               #When output from motion sensor is HIGH
            GPIO.output(3, 1)  #Turn ON LED
            print "Intruder detected!"
            image_name = datetime.now().strftime('%m-%d-%Y_%H.%M.%S')
            camera.capture(image_name + jpg_image)
            footage = image_name + jpg_image
            print "Image captured!"
part = MIMEBase("application", "octet-stream")
part.set_payload(open(footage, "rb").read())
email.encoders.encode_base64(part)
part.add_header("Content-Disposition", "attachment; filename= %s" % os.path.basename(footage))
msg.attach(part)
server = smtplib.SMTP("smtp.gmail.com:587")
server.starttls()
server.login(fromaddr, "PASSWORD")
server.sendmail(fromaddr, toaddr, msg.as_string())
print "Email sent!"
server.quit()

Just as a note, I did change out 'EMAIL' and 'PASSWORD'.

I am a total beginner so any help or advice is welcome!

Thanks

Code blocks in Python are defined by their indentation.
Your code to send an email is not indented, so it is not part of the While True : block and is never executed.

Thanks. If I indent it in line with the rest, i get this error:

Code: Select all

  File "securitysystem.py", line 48
    part = MIMEBase("application", "octet-stream")
    ^
IndentationError: unexpected indent

Hi!

I just tried it quickly, and it worked fine like this:

Code: Select all

while True:
       i=1
       if i==0:                 #When output from motion sensor is LOW
            GPIO.output(3, 0)  #Turn OFF LED
            time.sleep(0.1)
       elif i==1:               #When output from motion sensor is HIGH
            #GPIO.output(3, 1)  #Turn ON LED
            print "Intruder detected!"
            #image_name = datetime.now().strftime('%m-%d-%Y_%H.%M.%S')
            #camera.capture(image_name + jpg_image)
            #footage = image_name + jpg_image
            print "Image captured!"
            print "hello"
            part = MIMEBase("application", "octet-stream")

Thanks. If I indent it in line with the rest, i get this error:

Code: Select all

  File "securitysystem.py", line 48
    part = MIMEBase("application", "octet-stream")
    ^

There is a nice tool called "Python Beautify" over @ Dan's Tools website, simply paste in the code and it will indent it for you.
