In the Air Design Challenge

well, obviously I overestimated my free time when I designed the project concept, hence did not manage to complete the system. It was really fun though, and a great opportunity to play with some really cool stuff, like the TI launchpads, BBB, BitScope and various sensors. Also it was good excuse to upgrade my workbench equipment, so I am now better prepared for IoT hardware adventures.  I would not want to waste all the sensors I got, plus I do want to view and log air quality information f ...
One of, the most important aspects for an IoT solution, in my point of view, is device management, and more specifically the ability to receive over the air firmware updates (OTA). If OTA works, all other problems can be potentially solved. My architecture in the [Air ex Machina] project, consists of the following layers: backend, cloud based system. (e.g. airvantage) gateway - integration platform (e.g. openhab on BBB) sensor device (e.g. freeRTOS application on CC3200) Cloud based sys ...
As a software engineer, I do not normally work with custom hardware/electronics, so I was missing all basic components required for prototyping and was feeling kind of stuck. I did not want to spend the farnell budget on “consumable” general purpose electronic components, so decided to buy from ebay some cheap passive components in bulk, and use the competition budget on things that make more sense to buy from farnell. I ordered “kits” of resistors, capacitors, dimmers ...
So many sensors, so little time! Have been studying sensor datasheets all this time to make up my mind on what sensors to use. Found it very hard come up with a meaningful, doable and useful selection. I was tempted to go for a full blown list of these popular, low-cost and popular air sensors: http://playground.arduino.cc/Main/MQGasSensors You can find them on ebay for a few $ each, and it seems easy to get the readings: http://wiring.org.co/learning/basics/airqualitymq135.html However I h ...
Ambrogio did a very nice post on how to install java & openhab on BBB: http://www.element14.com/community/community/design-challenges/in-the-air-design-challenge/blog/2014/11/14/airmobile--4-… Follows an alternative approach for installing JAVA and OpenHab on BBB which is hopefully more newbie-friendly. 1) Where is my Beaglebone ?  I have never played with Beaglebone before, so I assumed it was more or less an RPi and did not bother to look at the details. Some differences ...
Downloaded CCStudio, after creating an account on TI http://www.ti.com/tool/ccstudio I am familiar with eclipse based IDEs (for java though), so I thought how hard can this be ? well... took me an couple of hours to find my way, and understand just the basics.   I started doing random stuff (like always) but this time nothing worked :-) so had to follow carefully this excelent guide (thank you for that shabaz): http://www.element14.com/community/groups/internet-of-things/blog/2014/10/1 ...
I am not the “read the manual” kind of person, so I searched for energia + cc3200, found this: http://energia.nu/pin-maps/guide_cc3200launchpad/ had a quick look at the instructions and started downloading/installing software. I’m runing windows 8.1 64bit, so I ‘ve installed drivers for FTDI via DPInst64.exe from cc3200_drivers_win Then extracted energia-0101E0013-windows.zip and runned energia, selected correct COM, loaded blink sample, upload and…. Opening COM ...
When I found out about this competition, I did a search to find similar projects and get ideas. I soon discovered these two: http://airqualityegg.com/ A community-led air quality sensing network that gives people a way to participate in the conversation about air quality http://smartcitizen.me/ Smart Citizen is a platform to generate participatory processes of the people in the cities. Connecting data, people and knowledge, the objective of the platform is to serve as a node for building produ ...
