Making the Internet of Things a reality

On March 18, 2014, Atmel and Arrow hosted a Tech on Tour (ToT) panel discussion in San Francisco’s SoMa neighborhood about the rapidly evolving Internet of Things (IoT). Moderated by Jeremy Geelan, panel participants included Omri Lachman of Humavox, Dominic Pajak of ARM, Christopher Kim of August Smart Locks and Atmel’s Kaivan Karimi.

ARM’s Dominic Pajak helped kick off the discussion by noting that the Internet of Things (IoT) has successfully sparked the imagination of both industry heavyweights and the masses. Indeed, a number of development boards, such as the Atmel-powered Arduino and Raspberry Pi, along with various wearables, are helping to put IoT technology in the hands of the people. Like all panel participants, Pajak noted that there were critical challenges – including adoption of standards and ensuring security – to overcome.

“IoT standards do exist today via the IETF (Internet Engineering Task Force), the very same standards body that originally defined IPv6. Specific examples include CoAP (constrained applications protocol) and 6LoWPAN. What is still emerging is the wide adoption and deployment of devices that run these protocols,” he explained. “Nevertheless, the IoT is steadily moving forward. While specific privacy policies have yet to be completely ironed out, the market will likely adapt to ensure consumer expectations are met.”

Pajak emphasized that he remained optimistic about the future of the IoT, which, if successfully implemented, could even lead to the rise of smart cities all over the world.

Omri Lachman of Humavox expressed similar sentiments, confirming that the IoT’s impact is already being significantly felt in the healthcare space, with devices such as connected heart monitors helping to change the lives of patients around the world.

“Our daily lives are more connected now than ever before. Everything is becoming centralized, both on a hardware and software level,” he said. “Plus, we are definitely starting to see various corporations, entities and ideas finding each other. From fashion and tech, to healthcare and wearables, it is all coming together and changing the way we do business.”

Meanwhile, Christopher Kim of August Locks noted that science fiction was quickly becoming fact thanks to the IoT, especially in the home automation sector, as is illustrated by Google’s recent acquisition of NEST.

“We are definitely past future shock. Consumers are becoming more familiar with the concept. It is no longer space age or futuristic to expect a house and its appliances to respond to the needs or commands of a resident or family,” he said.

“That being said, we take security and privacy very seriously, both on an external, practical level, as well as internally when we talk about opportunities for additional monetization.”

Similarly, Atmel’s Kaivan Karimi focused on how rapidly the Internet of Things is evolving by integrating various connected capabilities in our daily lives that range from consumer and health to intelligent, autonomous Google cars.

“For the IoT to thrive, the industry must continue to consolidate standards across multiple connected segments. In addition, security and privacy can definitely make or break the IoT, at least from a mass market perspective,” he said. “Of course there are always going to be people with evil intent. That isn’t the question. Rather, the challenge is how to best manage and protect the terabytes of valuable data generated by various IoT devices. I personally believe the need for comprehensive security and privacy policies are so pressing that it will prompt our legislators to take appropriate action.”

According to Karimi, future IoT models will likely see individuals opting in and out of specific data collection options, ranging from devices tasked with glucose monitoring to platforms like real time breathalyzers and wearables that measure physical responses to specific activities.

“In addition to wearables, cars are also going through a massive transformation, no less significant than the migration from analog to digital,” he added. “We are entering an age where drivers will not only step up their interaction with their vehicles, but cars will also start talking to each other to avoid fatalities, as well as monitor the weather in real time and even alert drivers to natural disasters such as tsunamis and flooded roads.”

Will Makers change Shenzhen?

Writing for the EE Times, Junko Yoshida says local culture in Shenzhen is rapidly changing, with a growing number of hi-tech workers reportedly joining the rapidly growing Maker Movement (chuang ke).

Indeed, RPTechWorks founder Yang Yango told Yoshida that “labor intensive” Shenzhen will eventually become a city known for fast prototyping with “shortened development” cycles. 

Qifeng Yan, ex-director of the Nokia Research Center in Shenzhen and currently director and chief researcher at Media Lab (Shenzhen) of Hunan University, expressed similar sentiments in an interview with Yoshida.

However, Yan noted that many individuals in Shenzhen lack free time and space. As such, the Maker Movement in Shenzhen (and China as a whole) is evolving into something quite distinct. 

More specifically, it is intertwined with the existing electronics ecosystem in Shenzhen, as Makers help local companies open DIY workshops, kick off fresh projects and even open new startups.

“The electronics market on Huanqiang Road has always been a destination for every EE. But its importance is increasing for the rest of us, with the maker movement catching on,” Yoshia concluded.

As we’ve previously discussed on Bits & Pieces, hardware development is becoming a more agile process with the aid of prototyping tools like Atmel-powered RepRap and Arduino boards – both of which are helping to facilitate innovation across the world and particularly in China.

“MakerSpaces will likely enable a new wave of tech startups in China as in the U.S,” Seeed Studio founder Eric Pan told Bits & Pieces during a recent interview. “To be sure, Makers working with their peers are now able to more easily realize their goals, while bringing products to market with new platforms such as e-commerce sites and crowdfunding.”

This 6X USB charger has a current monitor

Frank Zhao, an electrical engineer and DIY hobbyist, has designed a simple 6 port USB device charger with an individual current monitor on each port.

“The problem I faced was that I had too many devices to recharge at once, not having enough chargers and not having enough AC jacks,” Zhao explained in a recent blog post.

“Also my new Sony wireless headset was being picky about both the cable I use and the charger I use. I decided to troubleshoot this problem by building this tool.”

Key project specs include Atmel’s versatile ATmega328P microcontroller (MCU), an INA169 breakout board and an OKR-T10-W12.

The charging current is indicated using RGB LEDs. More specifically, blue means slow charge (under 250mA), green 250mA-750mA, red over 750mA and purple over 1500mA (for tablets).

“Wiring is done using 30 gauge Kynar coated wire. A decently capable wall-wart is needed, anywhere between 4.5V to 12V is acceptable and it must be able to supply enough current for all the devices to be charged,” Zhao continued.

“A DC/DC converter is used to increase efficiency, so a 12V wall-wart supplying 4A can actually charge about 8A total. The D+ and D- signals have the appropriate resistors to enable high charging rates on Apple devices – which is compatible with Sony, Samsung and other brands.”

Zhao also noted that he deliberately omitted a number of features from his charger due to cost and time constraints, including reverse polarity protection, input fuse, individual over-current cutoff and LED dimming.

Building a Yún-powered weather station

The Arduino Yún – designed in collaboration with Dog Hunter – is based on Atmel’s popular ATMega32u4 microcontroller (MCU) and also features the Atheros AR9331, an SoC running Linino, a customized version of OpenWRT. The Yún is somewhat unique in the Arduino lineup, as it boasts a lightweight Linux distribution to complement the traditional microcontroller (MCU) interface.

The Atmel-powered Yún – which hit the streets late last year – has been used in a wide variety of Maker projects that we’ve recently covered on Bits & Pieces, including an electricity monitor, mesh extender platform, Foursquare soap bubble machine, a Gmail (alert) lamp, water heater regulator and Evil Alarm System.

Today, we’re going to be taking a look at how Marc-Olivier Schwartz built a cloud-connected weather station with the Yún. Aside from the Atmel-based board, key hardware specs include:

  • DHT11 (or DHT22) sensor and 4.7K resistor (for humidity)
  • 
BMP085 sensor on a simple breakout board/Adafruit BMP180 sensor board (for pressure and temperature)
  • Photocell with a 10K Ohm resistor (light level)
  • Breadboard + assorted male-male jumper wires

On the software side, Schwartz used the Arduino IDE, Temboo, DHT library, the BMP085/BMP180 library, unified sensor library and a Google Docs account for the collected data to be analyzed and stored.

“The hardware connections for this project are actually quite simple: we have to connect the DHT11 sensor and then the part responsible for the light level measurement with the photocell. First, connect the Arduino Yun +5V pin to the red rail on the breadboard and the ground pin to the blue rail,” Schwartz explained in a detailed Adafruit tutorial.

“Then, connect pin number 1 of the DHT11 sensor to the red rail on the breadboard and pin number 4 the blue rail. Also connect pin number 2 to pin number 8 of the Arduino Yún. To finish up with the DHT11 sensor, connect the 4.7k Ohm between pin number 1 and 2 of the sensor.”

Next up is the photocell.

“First place the cell in series with the 10k Ohm resistor on the breadboard. Then, connect the other end of the photocell to the red rail on the breadboard and the other end of the resistor to the ground. Finally, connect the common pin to the Arduino Yún’s analog pin A0,” Schwartz continued.

“For the BMP085 or BMP180 sensor, connect the VIN pin to the +5V, GND to Ground, SCL to Arduino Yún pin number 3 and SDA pin to Arduino Yún pin number 2.”

According to Schwartz, multiple Yún boards can be used in various parts of a single residence.

“You can also customize the email alert part: you can build more complex alerts based on the measured data, or set the project to email you the sensor data at a regular time interval,” he added.

Soft electronics with Atmel MCUs

In a recent ReadWrite article, Lauren Orsini notes that soft electronics rocked the spotlight during Tech In Motion’s Wearable Technology Fashion Show, with models showing off accessories and clothing that lit up, matched moods and collected or displayed personal data.

As Orsini points out, a lot of wearable activity is centered around companies like Arduino and Adafruit. Both offer wearable electronic platforms powered by versatile Atmel microcontrollers (MCUs).

“Building electronics with your hands is certainly a fun brain exercise, but adding crafting into the mix really stretches your creativity,” says Becky Stern, Adafruit’s director of wearable electronics.

“Sewing is fun and relaxing, and adorning a plush toy, prom dress, or hat with a circuit of tiny parts can make you feel like you’re some kind of futuristic fashion designer. Playing with sensors and conductive textiles breaks electronics out of their hard shells and makes them more relatable.”

Indeed, just like their IoT DIY Maker counterparts, the soft electronics community has adapted various Atmel-powered platforms specifically for wearables, including the Arduino Lilypad (ATmega328V) (developed by MIT Media Lab professor Leah Buechley) and Adafruit’s very own Flora (ATmega32u4), which can be easily daisy chained with various sensors for GPS, motion and light.

“There aren’t any hard numbers on the DIY wearables community, but it’s clear from browsing members’ projects on Instructables that this group is far broader than your typical collection of electrical engineers,” concludes Orsini. 

”Stern also noted that there are 10,000 copies of Flora in the wild, [with] the company shipping them worldwide. According to Stern, it’s simple. Make electronics touchable and watch them take off.”
