Story

I have make recently a new project and I thought it would be a good idea to share with you Hackster community. I am continuously trying to add new functionality to this existing project.

I got motivation for this project from the project I made without PIR sensor which was based on image processing face detection. I realized that it was having many long python and XML scripts, which might be difficult for everyone to understand also in some cases detecting a motion and capturing image would be more effective.

Currently the project is capturing image when motion is detected with Raspberry Pi camera and sending that image as email notification. I have used python to write the script and have also published it. You should have two email accounts (I have used gmail), to send and receive emails. I have connected PIR sensor on GPIO 23. If your gmail uses SSL certificates you might need another port that 587

I am always looking forward to discussion about the project and comments, suggestions, etc.

Schematics

Connect Pin 3 of Raspberry Pi(5V Power) to the Power pin of the sensor.
Pin 5 of Raspberry Pi (GND) to the GND of the Sensor
And Pin GPIO23 of Raspberry Pi to the output Pin of the sensor(of course one can use different GPIO but then one should change to Python code)

Code

It is a simple python code just change the emails as you have. I have kept 10 seconds of delay after the image is captured. so the next movement will only be detected after 10 seconds. one can change to time with their requirements.

from picamera import PiCamera

from time import sleep

import smtplib

import time

from datetime import datetime

from email.mime.image import MIMEImage

from email.mime.multipart import MIMEMultipart

import RPi.GPIO as GPIO

import time

toaddr = ‘TO_EMAIL'

me = ‘FROM_EMAIL'

Subject=‘security alert'

GPIO.setmode(GPIO.BCM)

P=PiCamera()

P.resolution= (1024,768)

P.start_preview()

GPIO.setup(23, GPIO.IN)

while True:

if GPIO.input(23):

print(“Motion…”)

#camera warm-up time

time.sleep(2)

P.capture(‘movement.jpg')

time.sleep(10)

subject=‘Security allert!!'

msg = MIMEMultipart()

msg[‘Subject'] = subject

msg[‘From'] = me

msg[‘To'] = toaddr

fp= open(‘movement.jpg',‘rb')

img = MIMEImage(fp.read())

fp.close()

msg.attach(img)

server = smtplib.SMTP(‘smtp.gmail.com',587)

server.starttls()

server.login(user = ‘FROM_EMAIL',password=‘PASSWORD')

server.send_message(msg)

 server.quit()
