Now, you need to create the Python program. To do this, copy the code below into a file called “movement.py”. On Mac / Linux you can use the “nano” editor, on Windows, it is probably easiest to make the file using the Python editor 'IDLE” which is available from the Python program group on your start menu.
import time import serial import smtplib TO = '[email protected]' GMAIL_USER = '[email protected]' 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)
Before you run the Python program, there are some configuration changes that you need to make. These are all up near the top of the file.
The program assumes that the emails are being set from a gmail account. So, if you don't have one, you might like to make yourself one, even if it is just for this project.
Change the email
address next to “TO” to the email that you want to receive the
notifications. This does not have to be your email address, but
probably will be.
Change the email address next to “GMAIL_USER” to the email address of your gmail address and alter the password on the next line to the password you use to retrieve your emails.
If you want to, you can also change the subject line and text of the message to be sent, on the lines that follow.
You will also need to set the serial port of the Arduino by editing the line below:
ser = serial.Serial('COM4', 9600)
When you have made these changes, you can run the program from Command Prompt / Terminal with the command:
python movement.py
When a movement is triggered you should get some trace like this and shortly after an email will arrive in your inbox.
Notice also the “Too soon” messages.
