If your BeagleBone is not accessible, for instance, it's monitoring something at your home while you're out, you might still need a way for it to send you information.

SMTP_pass = 'password'

def send_email(to, subject, body):
  msg = MIMEText(body)
  msg['Subject'] = subject
  msg['From'] = SMTP_email
  msg['To'] = to
