Additional Sensors for Home Alarm

[PiGobbler]

Hi all,

I am relatively new to programming and thought what better way to get into it than with a Raspberry Pi! Apologies in advance if my question is very basic or I have missed some information but here goes..

I am currently tinkering with a project I saw on the Raspberry Pi website called the PiLarm.

I have everything working so far but i'm struggling to add additional sensors to the code.

At the moment I have 1 PIR sensor which when triggered sends a notification email with image attached. I would like to add an additional PIR sensor and a reed switch also. I have tried multiple ways of adding these into the code but so far none have worked.

I do have the PIR and Reed Switch working individually in a separate programming but i just can't get my head around integrating them into my code so that when triggered each sensor will send the notification email.

I have attached my code and any help would be greatly appreciated!

Thanks in advance.

Code: Select all

#!/usr/bin/python

import subprocess
import datetime
import time
import os 
import RPi.GPIO as GPIO

GPIO.setmode(GPIO.BCM)

pir_pin = 1
blue_LED_pin = 7

GPIO.setup(pir_pin, GPIO.IN)
GPIO.setup(blue_LED_pin, GPIO.OUT)
GPIO.output(blue_LED_pin, GPIO.LOW)

# --------- Main Program ---------
previous_pir = 0

while True:
	current_pir=GPIO.input(pir_pin)	
	if previous_pir==0 and current_pir==1:
		with open("/home/pi/Alarm/armed.txt", "r") as fo:
                    fo.seek(0, 0)
                    status = fo.read(1)
                fo.closed
                print "Motion detected, armed status: " + str(status)
		if (status == "1"):
		    subprocess.call("mpg123 /home/pi/Alarm/motiondetect.mp3", shell=True)
                    time.sleep(5)

                    fo.closed 
		    if (status == "1"):
		        print "Correct passcode not entered, emailing picture and sounding alarm."
                        grab_cam = subprocess.Popen("sudo fswebcam -r 640x480 -d /dev/video0 -q /home/pi/Alarm/pictures/%m-%d-%y-%H%M.jpg", shell=True)
                        grab_cam.wait()
                        todays_date = datetime.datetime.today()
                        image_name = todays_date.strftime('%m-%d-%y-%H%M')
                        image_path = '/home/pi/Alarm/pictures/' + image_name + '.jpg'
                        subprocess.Popen('echo "Here is your intruder:" | mail -a ' + image_path + ' -s "Intruder Alert" *****@gmail.com', shell=True)

                        GPIO.output(blue_LED_pin, GPIO.HIGH)
		        subprocess.call("mpg123 /home/pi/Alarm/alarm.mp3", shell=True)
                        subprocess.call("mpg123 /home/pi/Alarm/surrender.mp3", shell=True)
                        subprocess.call("mpg123 /home/pi/Alarm/alarm.mp3", shell=True)                       
                        GPIO.output(flashingLight_pin, GPIO.LOW)
                        del_img = subprocess.Popen("sudo rm -rf  " + image_path, shell=True)
                        del_img.wait()
	previous_pir=current_pir
	time.sleep(1)

Hi

I know it's a while a go, but did you manage to add additional pir/switch, I'm currently building the PiLarm, I'm having issues with using picamera (just submitted a post), but my next step would also be adding door switch and additional pir, would be interested to see your results.
