Sensor networks are the way to go if you have to monitor environmental data such as temperature in a wide area. Usually you need some infrastructure, including servers for communication, data storage, and the like and to manage the network and make the sensor data available. This session shows how you could build a sensor network, including the infrastructure, based on embedded devices only. It uses several embedded devices such as a Raspberry Pi, a BeagleBone Black, a Cubieboard2, and an i.MX6-based Cubox-i. The idea is to use cheap standard devices in combination with Java technology to realize a sensor network. în plus, it shows mobile clients, such as a smartwatch, for visualizing the sensor network data.

BeagleBone Black Wireless hurries up development
When you’re thinking of development boards, it’s not just about the Arduino and Raspberry Pi. BeagleBone TI-friendly este acolo în amestec, de asemenea, struggling for your attention
Which is a justified reason to talk about some developments around the BeagleBone Black single-board computer: there’s the new version and 2 new Capes from the BeagleBone team.
As well as the BeagleBone Black Wireless (enumerate mai jos), you will also find 2 brand new ‘cape’ add-on boards for the existing BeagleBone Black.
BeagleBone Negru Wireless
Foremost, the BeagleBone Black Wireless, which is for the most part a BeagleBone Black with on-board 802.11 b/g/n 2.4GHz Wi-Fi as well as Bluetooth. It’s following in the route of the Raspberry Pi 3 by building in Wi-Fi support to streamline wireless communications.
motopropulsor sa este Texas Instruments Sitara AM3358 1 GHz ARM Cortex-A8
„Similar cu BeagleBone negru, the wireless maintains HDMI output, Port serial de depanare, interfață USB PC, USB 2.0 gazdă, reset and power control buttons, and brings 2 more status LEDs for WiFi and also Bluetooth,“Afirmă BeagleBone.org.
“Also kept is the 4GB of on board eMMC memory with Debian Linux preinstalled, enabling the BeagleBone Wireless to boot in approximately Ten seconds and have you developing through the browser in fewer than Five min’s making use of simply a single USB cable.”
You can look at the specifics of the board by expanding the graphic above, and a data sheet is the following for download.
Take note that it marks the introduction of the Octavo OSD3358 SiP, integrarea funcționalității BeagleBone într-un singur pachet BGA.

Considering that we’re speaking about plastic card-sizes peices of kit, space is required to be made for extra features. This in essence means this particular BeagleBone has displaced its 10/100 Port Ethernet, producing space for a TI WL1835 WiLink wi-fi interface.
The full specifications:

Not forgetting the the two new capes…
Wireless Cape addon
Notice that the new Wireless Cape takes BeagleBone Black above the abilities of BeagleBone Black Wireless, points out Steve Bush in his news piece on the release. Este alimentat de la Texas Instruments WiLink 8 (WL1837) dual-band industriale (2.4GHz & 5GHz), 2× 2 MIMO Wi-Fi, Bluetooth și Bluetooth inteligent (otherwise known as Bluetooth LE), that also comes with Zigbee and NFC.
The cape unfolds with Debian Distribution pre-installed and 4GB of on board eMMC Flash memory. “Designers might be developing employing their browser in less than Five min’s by means of just one single USB cable,“, A declarat Farnell.
Display cape addon
Note there’s yet another Display cape addon sold. Acesta oferă conexiuni pentru o 4.3in. color touch-screen an LED backlight and capacitive overlay “for a mobile-like interface”.
The cape is aimed at interactive projects, sisteme integrate și set up-uri de sine stătătoare.
Pricing is approximately ￡55 for the BeagleBone Black Wireless, ￡35 for the display cape addon as well as, ￡44 for the wireless cape addon .
