This paper introduces the design and prototype of a new home automation system that utilizes GSM technology as the network infrastructure to connect its components. The proposed system is composed of ...

Hardware To start, set up the hardware as shown below. Naturally, you’re going to need a valid SIM card to fully use the SIM800L module. For compactness, my setup was tested with a 1S (3.7-V) Li-ion ...

He put it all together on proto-board, although soldering the FM radio module was a bit tricky. The Arduino code is quite simple, and available for download (zip file).

When we send SMS to GSM module by Mobile, then GSM receives that SMS and sends it to Arduino. Now Arduino reads this SMS and extract main command from the received string and stores in a variable.

The module, or shield, was developed in conjunction with Telefónica’s Physical Internet Laboratory and is available to purchase. The open-source GSM Shield comes with a Telefónica SIM card ready to be ...
