    Galileo Send Real Time test result VIA email


      This is a simple example to write python script and send any real time data VIA email. Might can save you some

      time when you need send the real time data. you can play aroud with it.

      Maybe can used at the access control system send the sensor status every half hour when you outside for weekend,

      so you get quick response when some animal breaked in.

      or you can monitor the temperator of your lovly Garden.

      Don't use this as a spam generator!
