One of the essential elements of building IoT project is the ability to connect devices. Wi-Fi and Bluetooth are good low cost choices, but they work only at close ranges, or in hotspot areas. When the device needs...

  In this project we’re going to show you how to request sensor data via SMS with the Arduino. As an example we’re going to request the temperature and humidity from a DHT11 sensor. To send and...

A friend of us just developed this amazing library to connect Arduinos to SIM Modules: donate! It’s a library developed for Arduino’s shields that support SIM900/SIM908. You can find many shields on market supporting SIM900 and SIM908...

A few days ago we showed you how to use the Raspberry GSM shield using the arduPi library created ​​by Libelium and ​​available under the GNU General Public License that you can download from Cooking Hacks. Now...

It’s small but packed with features. The GSM alarm we present today, sports a PIR motion sensor, can be battery operated and it’s capable to communicate via GSM. It can transmit alarm conditions and receive commands from...

  This post is one in a series showing you the main features of the GSM /GPRS/GPS shield and of its related library. The examples are great to have inspiration and reuse the material to create your...

A few months ago, we presented a powerful shield that can enable devices from the Arduino family (Uno and Mega) to interface with the SIMCOM modules SIM900 and SIM908. Such modules provide integration with the world of...

. Connected to a burglar alarm or fire alarm in the event of making phone calls playing voice messages. Controlled via DTMF actuators can operate on the spot. In recent years we have introduced several telecontrols based...

Shield for Arduino designed and based on the module GSM/GPRS SIM900 or the GSM/GPRS & GPS module SIM908, to make calls, voice and data connections via GPRS.     HARDWARE INNOVATIONS This new version (old Arduino GSM...

The device is based on a GSM/GPRS module with included GPS. Its main function is to detect and communicate its own geographical position using, on the choice, the cellular phone reference system or the GPS. Its small...

Allows you to create data connections on the GSM network through a standard USB interface. The cellular modems, particularly USB-stick ones, are now at very affordable prices, however they’re limited: they are explicitly designed for Internet connections,...

Some post ago we presented a PCB to mount the SIM900 module. The project is used in our GSM remote control and the Arduino GSM Shield. The dimensions aren’t big (1.75×1.95 inches) but in some cases they...
