Internet of Things ( IoT )

Next generation Internet is " Internet of Things " , connecting everything with net . Data exchanging between these devices will be supported by Cloud network system . Now COSM (earlier it was Pachube) is a free cloud provider for live data exchange, mainly from live sensors as public feed or private feed. They are providing APIs for data communication over the net through COSM services.After free signing up with COSM you can create FEED with ID and Data streams.Under a single FEED ID you can add many number of Data streams.You can update the FEED by some regular intervals automatically with ready made applications ( Android based applications are available in the google market , PC based applications also available) or user applications.A link for sample feed from my smartHome project.The data is live from sensors installed in the smartHome ( Android based system for Integrated Home Automation).

The data shown in the graph is collected from real sensors and passed to Android based application , then it will send to COSM server with the help of JPachube libraries.With this feeds we can create visual graphical representation and set the Trigger value for getting trigger to other URL.
My smartHome system is connected with COSM server and updating datas collected from the system, and the feed -data streams can be viewed from anywhere in the world by downloading the data stream from COSM and can be displayed in the attractive and useful format with some application in Mobile phone (Android based application) or Tablet PC
smartHome -System Unit (Android powered)

ARM-11 samsung cpu S3C6410 is used in this system

OS is Linux+Android 2.3.4

smartHome application - Menu for controlling the Devices in Home,simultaneously status will be updated in COSM.


ON/OFF Schedule can be set for each device.

  1. The following time I learn a weblog, I hope that it doesnt disappoint me as a lot as this one. I imply, I do know it was my option to read, but I truly thought youd have something fascinating to say. All I hear is a bunch of whining about something that you possibly can fix should you werent too busy in search of attention. programmieren berlin

BEAGLE BONE BLACK FOR EMBEDDED APPLICATION

Happy news for embedded developers, with the introduction of BeagleBone Black credit card sized single board 1GHz computer.We can develop high end embedded system with Operating system support in the ARM7 platform.Processor from Texas Instruments AM335x Cortex A8 Sitara . Advantage of this small system is many more ,it will operate on 5V dc supply with 500 MA,so with USB cable connected to 5v source can operate the system.Most of the desktop computer features available with this board.As a standalone system keyboard and mouse can be connected with USB.Out put display available at micro HDMI port,that can be connected to any latest TV with HDMI input.LAN port is provided for network access.USB device(slave) port also available for connecting with PC,the board will act as storage device.Same time there is an internet pass-through via USB.For the starting of development some startup file provided in the eMMC (on board flash memmory 2GB),by opening the file it will direct to beagleb
