Prototype XBee and Other Wireless Projects with Tinylab

Posted on: No Comments

You might remember our post about the XBee product turned Indiegogo superstar last year–Plexidrone. Well, there’s another XBee related Indiegogo campaign making headlines. Tinylab is a prototyping platform, developed by Bosphorus Mechatronics, simplifying IoT development with an all-in-one Arduino-based solution.

Tinylab reduces the need to stack multiple Arduino shields, pull out the breadboard and jumper wires, or hunt down that spare LTH sensor in your drawer. This flexible and extensive development board supports Arduino and other development environments, hosts 20 Digital I/O, and additional sensors come pre-attached. And, perhaps most exciting, is the support for a number of wireless technologies like XBee, Bluetooth, or Wi-Fi with the ESP8266 chip as seen in the graphic below.

The Indiegogo campaign got off to a great start and Bosphorus Mechatronics quickly exceeded their goal of $25,000. The crew is shipping development kits to their campaign supporters in May and one level of support will even earn contributors a development kit that includes XBee RF modules.

Also, to demonstrate the board’s capabilities, the team at Tinylab created an wireless lighting demo. The video is showing wireless control of a lightbulb with commands sent over XBee. Check out the video below.

FogFinder Relies on Arduino and XBee to Tap into New Water Source

Posted on:

No, it’s not possible to create water out of thin air. But, with a bit of engineering, scientists in Chile are turning foggy air into a reliable water source for nearby residents. The process is almost entirely natural–the sun desalinates the water, the winds push the water to a higher elevation, and gravity allows the collected water to flow back down to the village.

Using large fog collectors, which consist of mesh mounted on a rigid structure, to capture impacting fog water droplets from the air and tapping into the natural processes mentioned above, fog collection could be an economical way to gather and distribute clean water.

The fog collectors are typically installed on hillsides and remote areas where fog is abundant. These installations are especially common in arid climates in Chile where rain runs scarce. As fog passes through, the droplets impact the mesh fibers and collect in a trough below. One of the real challenges and opportunities for innovation lies in determining where to install these collectors, how to orient them, and understanding how efficient they are at collecting water from the air.IMG_0420

While at the Universidad de los Andes in Santiago Chile, Richard LeBoeuf, Associate Professor at Tarleton State University, and Juan de Dios Rivera, of the Pontificia Universidad Católica de Chile, developed a new type of sensor called the “Liquid Water Flux Probe” to measure the availability of water at current and potential fog collector sites. The sensor measures the liquid water content and speed of the fog and can be used to understand the optimal location and orientation for each of the collectors.

The sensor is part of a larger system called FogFinder, which Richard LeBoeuf developed in collaboration with Juan Pablo Vargas and Jorge Gómez at the Universidad de los Andes. Together they designed and engineered the FogFinder system, which includes wireless networking.

With the primary challenge of measuring fog liquid water flux out of the way, the team needed to design a device capable of being deployed in extremely remote environments and easily retrieve sensor data. Since there is no power source to plug into out in the desert, the options are either solar or wind power. Due to their simplicity, a separate solar power system, comprised of a solar panel, battery, and charge controller, is used in conjunction with the FogFinder unit.

To facilitate the collection and transmission of sensor data, the team chose to build the foundation of FogFinder with Arduino and XBee. Both components offered a fast and easy way to get started prototyping the design. Each sensor node is comprised of an Arduino Mega and XBee module, and the team even designed and built custom boards to regulate voltage, interface the sensors and store data on a micro-SD card.

The node collects data on the following parameters:

  • Liquid water flux
  • Humidity
  • Temperature
  • Flow-rate from fog collectors
  • Pressure
  • Wind speed
  • Wind direction

The team settled on using XBee for local wireless communication since it provided greater range and required less power than Bluetooth. The ZigBee protocol also offers the flexibility to create a mesh network and configuration settings to conserve power-saving valuable battery life. With external antennas and mountain top to mountain top placement of each radio, they have achieved a reliable 1 km link.

Once the data is collected, it’s sent to a remote server over a cellular network. Using a BeagleBone SBC and a cellular modem, data is taken from the local XBee ZigBee network and can be accessed on a remote computer. This data is then analyzed to assess the performance of the fog collector.

What’s next for FogFinder? As the team wraps up the prototyping stage, they’ll be conducting calibration in a wind tunnel to prepare for field tests.  Once the testing phase is complete, the team will work to deploy them as part of a pilot program and start connecting more Chilean residents to a clean source of water.

The FogFinder project has received support from the Universidad de los Andes through its Fondo de Ayuda de Investigación, Andes Iron – Dominga, and the Pontificia Universidad Católica de Chile.

The Next Chapter in the Digi Story: Connect with Confidence

Posted on:

This year represents a transformational moment for Digi as a company. We celebrated our 30th birthday. We have a new CEO. We’ve made a new acquisition and have brought on customers that represent some of the world’s most innovative companies.

Not too long ago, we held a retirement gathering for one of our long time employees. She’d been with the company for 28 years. She and others who have been here for the long haul started sharing stories about how things were in the early days. The stories were the perfect anecdote for how much things have changed over the years—over the decades. Those stories show how much Digi have evolved. But just as much as they show Digi’s evolution, the stories represent our powerful foundation of strength that we’re carrying into the future.


About 18 months ago, we set out to define how we would bring the meaning of that foundation and evolution to our customers, partners and the public in the clearest way possible. We asked ourselves: “how can our brand embody the sentiment of the stories our employees tell? How can our brand articulate why those innovative companies turn to Digi over others?”

To start, we went back to our roots. To our core value: listening. With 30 years of history and our diversity of experience, that’s what made sense. You can find Digi products in vast oil fields, intensive care units, crowded freeways, factory floors, and in retail stores on Black Friday. There are millions of devices deployed in the world, each with a critical task to perform. We needed to talk to the people who depend on those connections in order to articulate our mission best.

So, we conducted deep customer and partner interviews, employee surveys and spent time with our partners. All in all, we went through 100 interviews, 125 surveys and 10 workshops—more than 500 hours of listening.

It led us to a key finding: it’s time to modernize the Digi brand, but to emphasize not change, who we are at our core.

So, here we are today.

What is the new brand?

At its core, we have the brand promise, what you can expect from Digi, why would you choose Digi:

Digi works with you to solve mission-critical and business-critical machine communication challenges in the most demanding environments. You get proven, no-nonsense solutions that work, and keep working. With Digi, you can create, deploy and manage your M2M and IoT connections with confidence.

What we heard in those 500+ hours of research is that there’s something our customers get when they choose Digi: trust. They trust the people, the products and the company.

In short, we help you CONNECT WITH CONFIDENCE.Digi-Logo-Timeline

You’ll see “connect with confidence” as our new tagline and continued promise to you. You’ll also see the evolution of the Digi corporate logo. It represents exactly what the tagline does: sturdy, solid, reliable Digi. We’ve also gotten Digi out of the box and added a new shade of green—energetic and agile. We are company that our customers can connect with confidence, and we’re dedicated to doing so with fresh energy.

Thank you to everyone who took the time to play a role in this process. Listening to you has helped us get to a place where we’re truly sharing who we are with the world.

We’d love to hear your thoughts in the comments section below.

Look What I Made: XBee Project Gallery Update

Farm Safety Wearable
The sweep auger motor plugs directly into an outlet on the receiving box. This receiving box and transmitter each have an XBee wireless transceiver inside. When the remote control is powered on, the first LED lights up. When the safety cord is connected, the second LED lights up. At this point, the sweep auger is off.

Connected Greenhouse
Using an Intel IoT Gateway, the wireless systems turns daily farming data into a more meaningful decision-making. Sensors for temperature, humidity, pH, and luminosity in the greenhouse pass the data to the local Galileo gateway. Galileo transmits data using XBee to an Atom processor-based gateway, and then uploads all the information to the cloud system.

Wireless Boat
This RC boat uses XBee for wireless control. The controller is fashioned from an old Air Hogs controller. An Arduino Pro mini is connected to the XBee, analog stick for steering, LEDs, and triggers buttons.

Makers Turn to XBee for Wireless Projects at World Maker Faire 2015

Posted on:

Another year. Another Maker Faire. And more wireless XBee projects! The Digi team was on the ground at this year’s World Maker Faire in New York and found some impressive XBee projects during the weekend. Here’s a quick recap of the event.

Telemetry for Land and Air
The first XBee project found at Maker Faire was created by Kerron Manwaring. Starting out as just a hobbyist, his passion for electronics drew him to a career in engineering. He was showing off a rover and drone powered by microcontrollers.  As you can see in the pictures below, both of the land and air vehicles had XBee onboard, which he used for sending telemetry.

 

Tobor – The Giant Robotic Arm
The next project we came across was Tobor, a 12-foot haptic robotic arm. The arm has haptic ability, which means it can be controlled by a glove using movement sensors and motors.  When the user wearing the glove moves his or her hand, Tobor responds by mimicking that movement. How was XBee involved? Commands from the glove telling the arm how to move are sent wirelessly over XBee.

 

Digi Connections at Maker Faire 
Digi Internship Alumni Jonathan Young showed off his automatic drum machine as well as the Sentry Gun he built using the experience he had over two summers at Digi. Also, Chief Innovator Rob Faludi posed for his annual photo with young maker Quinn of Qtechknow. Quinn has been mentioned in several previous blog posts, he’s been using XBees for at least four years now! Learn more about what he’s up to at his website.

 

World Maker Faire NYC was as crowded as it’s ever been and we’re already looking forward to the next one. If you didn’t make it out this year,  you can click here to check out Maker Faire’s slideshow of highlights from the weekend.
