A big thank you to all who participated in the In the Air IoT Design Challenge, the partners, element14 and the wider public have been deeply impressed by the projects we've seen to help create a greener, cleaner world.
It was not an altogether straightforward matter to pick a winner: however, in the end, we've awarded the prizes to the following individuals and their projects.
The Grand Prize
The Grand Prize has gone to Christever del Rosario of New Zealand for his Carbon Footprint Monitoring System.  His project's final summary can be read by clicking here.
Christever will receive:
  1. 15 inch MacBook Pro with Retina Display
  2. U1273A OLED Multimeter from Keysight
  3. SimpleLink™ Bluetooth Smart®/Multi-Standard SensorTag (Manufacturer Number: CC2650STK)
Community Choice Winner
The Community Choice Winner by a clear plurality of votes was Inderpreet Singh of India for his Firecracker Aftermath Analyzer.  His project's final summary can be read by Clicking here.
Inderpreet will receive:
  1. 13 inch MacBook Air
  2. SimpleLink™ Bluetooth Smart®/Multi-Standard SensorTag (Manufacturer Number: CC2650STK)
Additionally, we felt that two other projects deserved recognition as Honourable Mentions; both engineers will receive a SimpleLink™ Bluetooth Smart®/Multi-Standard SensorTag as a prize.
Honourable Mention 1
Our first Honourable Mention goes to Ambrogio Galbusera of Italy for his AirMobile project. The project summary can be found by clicking here.
Honourable Mention 2
Our second Honourable Mention goes to Janis Alnis of Latvia for his Air Quality Monitoring In School Classes project.  The project summary can be found by clicking here.
Thank you once again to all the participants for their time, energy and effort: we look forward to more innovative and exciting design challenges in 2015 coming to life.
Checkerspot Butterfly
For the Checkerspot Butterfly's sake, solutions will take wing.
Welcome to the last week of the In the Air Challenge. element14, Texas Instruments, Würth, Cisco, the Eclipse Foundation and Sierra Wireless all been intrigued and fascinated by the solutions that the challengers have been putting together since the challenge began.  We look forward to seeing the final summaries of the projects by the end of this week.
Please note: final submissions are due by end of Friday, February 27th - we will grant leeway of up to 24 hours should there be any technical difficulties.
As ever, if you have questions please let me know.
Good morning and thank you to all who applied for the In the Air Design Challenge.  It hasn't been easy for the partners to identify the competitors for this challenge: we received many ambitious (sometimes too ambitious) and detailled proposals.  However, we've selected the following competitors:
  • Janis Alnis (Latvia)
  • Dominic Amann (Canada)
  • Ravi Butani (India)
  • Christever del Rosario (New Zealand)
  • Ambrogio Galbusera (Italy)
  • Dragan Knezevic (Serbia)
  • Crystal Knodel (U.S.)
  • Ryan Longlong M. Labutap (Philippines)
  • Manolis Nikiforakis (Greece)
  • Inderpreet Singh (India)
  • Gan Eng Swee (Singapore)
  • Anshul Thakur (India)
  • Frederick Vandenbosch (Belgium)
  • Dale Winhold (Canada)
  • Michael Wylie (U.S.)
You can find out more about their projects by clicking here.
Please note: the final deadline for the challenge has been adjusted to February 27, 2015.
Thanks again, and to our competitors, Good Luck!.
Q: What is the range of Sub 1-ghz devices ? how much will the range be greater then Wi-Fi?
Sub-1 GHz devices have much greater ranges than Wi-Fi devices.  The Range of the sub-1 GHz devices can be over 1 km while Wi-Fi range is closer to 100m.
Q: If I want to use Sub 1GHz on my MCU/edge device, what do I need to transfer data from the edge device and eg a Linux based gateway device? Thx.  I mean what do I need on the gateway?
Here is software information for TI’s Sub 1GHz solution -
Q: Are there any GMS based products focused on IoT (low power)?
TI has many wireless technologies including Wi-Fi, Bluetooth, Zigbee, 6LowPAN, Sub 1Ghz and more.   GSM is not supported in our portfolio.
Q: Does TI have any portfolio of sensor's like moisture, humidity or some chemical sensors for farming applications ?
TI does have moisture/humidity, temperature, and chemical sensors. We also have reference designs that are targeted at similar applications to farming.  For example, The Gas Sensor Platform  Reference design with Bluetooth low-energy (BLE) is intended as a reference design that customers can use to develop end-products for consumer and industrial applications to monitor gases like carbon monoxide (CO), oxygen (O2), ammonia, fluorine, chlorine dioxide and others.  For more information see TI’s web -
Q: I am currently programming on TI Tiva C series mcu's. What are the difference in programming CC3200 and TI Tiva C processor?
Both the CC3200 and the Tiva contain ARM-M4 processors so they have a lot in common.  However, there are software tools designed specifically for the CC3200, but the IDE tools were derived from Tiva tools so there are several similarities.
Q: What LaunchPad / MCU would you suggest for application which want to use Wi-fi and sensor mesh network ( much like Zig bee) but not as costly as Zig bee?
The only other mesh network that TI offers is 6LoWPAN.  However, I would strongly urge you to consider ZigBee.  TI already has a Wi-Fi to ZigBee gateway designed that is much easier to build off of.  Here is a link:
Q: Regarding on both ends (edge and gateway) the Sub 1GHz, if I want a Linux based gateway are drivers provided that support Linux?
Linux drivers are not provided today, but stack is available online for MCU -
Q: Great presentation! Is there a (low memory footprint) 6LoWPAN stack you recommend, for MSP430 microcontrollers?
Here are some options.   Look at TI web for how to get started – look down the page for getting started section -
Q: What connectivity model would you recommend for highly mobile applications? 10+ kms
Sub-1 GHz has the greatest range, and can support ranges in over 10km.  Another option might be to look at cellular.
Q: When using Wifi based MCU/edge devices I would think MQTT is a good option. What do you recommend for other communication means?
MQTT is good communication means.  TI has a great cloud ecosystem where our partners have communication solutions built on TI products.
Q: Any particular recommendations for the sub1 or cellular (What are the advantages / disadvantages of each?)
Sub-1 GHz can run on very low power, and enables a relatively low throughput.  The sub-1 GHz frequency band is less crowded.  It requires a larger antenna and there are restrictions on duty cycles at certain frequencies.    You basically create your own network with both nodes and network and services.  This solution is supported with standard products available for TI and distribution.
Cellular is owned by carriers so you would need to work with them to leverage their network and any services.
