GSM plug is a normal plug but with a great advantage: you can power it on by sending an SMS.

How does it work :

  • GSM-plug is an independent controller which can be guided through a GSM network available.
  • It is based on gsm-shield for Arduino which accepts short messages (SMS).
  • A simple communication protocol with simple commands is built in the GSM-plug in order to control any device connected to the GSM-plug.
  • This is shown here with a lamp connected to it that can be turned on or off through any mobile device by sending the relevant command.
