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. Auk þess, it shows mobile clients, such as a smartwatch, for visualizing the sensor network data.

BeagleBone Black Wireless hurries up development
Þegar þú ert að hugsa um þróun leiksvið, það er ekki bara um Arduino og Raspberry Pi. TI-vingjarnlegur BeagleBone er í blöndu, líka, struggling for your attention
Which is a justified reason to talk about some developments around the BeagleBone Black single-board computer: Það er ný útgáfa og 2 Nýju Capes frá BeagleBone liðinu.
Auk BeagleBone Black Wireless (listed below), þú verður einnig að finna 2 brand new ‘cape’ add-on boards for the existing BeagleBone Black.
BeagleBone Black 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 ásamt Bluetooth. Það er eftir á leiðinni á Raspberry Pi 3 by building in Wi-Fi support to streamline wireless communications.
fullbúinn hennar er Texas Instruments Sitara AM3358 1GHz ARM Cortex-A8
“Similar to the BeagleBone Black, the wireless maintains HDMI output, raðnúmer kemba tengi, PC USB tengi, USB 2.0 vélin, endurstilla og máttur stjórna hnappur, and brings 2 more status LEDs for WiFi and also Bluetooth,"Segir 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.
Hafa í huga að það markar kynningu á Octavo OSD3358 SIP, samþætta BeagleBone virkni í einum BGA pakka.

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 Ethernet tengi, producing space for a TI WL1835 WiLink wi-fi interface.
The full specifications:
:: AM335x 1GHz ARM Cortex-A8
:: SGX530 grafík eldsneytisgjöf
:: NEON fljótandi-lið eldsneytisgjöf
:: 2x PRU 32bit 200MHz micro-controllers
:: WiLink 1835 802.11b / g / n 2.4GHz WiFi, blátönn, plus Bluetooth Smart Module
:: USB viðskiptavinur: máttur, kemba og tæki
:: USB gestgjafi
:: Micro HDMI framleiðsla
:: 2x 46 pin haus
:: 512Megabyte DDR3 800Megahertz RAM
:: 4GB Inserted eMMC Flash with Debian Distribution pre-installed
:: Micro SD nafnspjald rifa
:: Cloud9 IDE um Node.js w / BoneScript bókasafni
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. It’s powered by Texas Instruments WiLink 8 (WL1837) iðnaðar tvískiptur-band (2.4GHz & 5GHz), 2× 2 MIMO Wi-Fi, Bluetooth og Bluetooth Smart (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,"Segir FARNELL.
Sýna Cape addon
Note there’s yet another Display cape addon sold. It provides connections for a 4.3in. color touch-screen an LED backlight and capacitive overlay “for a mobile-like interface”.
The cape is aimed at interactive projects, innbyggð kerfi og sjálfstæða setja ups.
Pricing is approximately ￡55 for the BeagleBone Black Wireless, £ 35 fyrir sýna cape addon eins og, £ 44 fyrir þráðlausa cape addon .
