The service formerly known as Cosm is now dubbed Xively: The Internet of Things promises to revolutionize the relationship between people and their world, but bringing transformative connected products to market takes more than a great idea. It requires tools, infrastructure and know-how that most businesses don’t have the time, money or capacity to obtain….
SparqEE is a Cellular development board that gives you Wireless Worldwide. It provides boards for both, Arduino and Raspberry! Important Facts: The CELLv1.0 uses a 2G+3G chipset, which means it will use 3G primarily worldwide and only fall back to 2G if 3G is unavailable. Question: Why are 2G (GSM/GPRS) devices less expensive? Answer: some…
Once again we have prepared some examples related to the GSM/GPRS & GPS shield. In previous posts we have seen how to handle SMS, make calls and use the GPRS connection to send email or download data from Internet pages. The shield has been developed to accommodate both forms of SIMComs: SIM900 and SIM908: the…
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 remote. It’s also capable to indicate problems such as is insufficient voltage supply or tampering. It’s not so…
After having shown several examples regarding the use the GSM/GPRS & GPS shield with calls and text messages we are now going to present some applications that involve GPRS data. Thanks to the inet.h class the shield can indeed connect to the internet and its various applications. We ‘ll see how to use the Arduino as…
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 own solutions. We already talked about how to use the shield to make calls, send DTMF tones and…
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 GSM, GPRS and GPS and all is achieved through very simple Arduino commands thanks to the open-source dedicated…
We wanted to create a basic tool to experiment with the RN-42 Bluetooth module so we created obviously a Demoboard. The RN-42 Hardware module The RN-42 is a Bluetooth 2.1, Class 2 module with a PCB integrated antenna with a communication capability of about 3 Mbps. The version with the integrated antenna has…

Few years ago we were in a need for easy way to get our green walls use GSM network to communicate with our servers. In the very first prototype we…
. 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 on the SIM900 GSM module. We released schematics and code for a gate opener (that activates when receiveing…
After the smartphones revolution that led us directly to the internet in our pockets the next one is already in place a will bring the Internet directly into objects. I often read lots of posts on a daily basis in which people try to define the Internet of Things: since a long time I…
AT command tester is a free online software tool that is used to test AT commands and other functionalities of GSM modems. The friendly user interface allows developers to Configure and connect to modem ports Send single or batch of AT commands Perform modem diagnostics Establish 3G or GPRS call Collect and save modem logs…
