One Small Step for XBee, One Giant Leap for Wireless

Posted on: No Comments

This winter, Soarex, a NASA sounding rocket, will be launched into space with XBee on-board.  The three-node network is the first XBee ZigBee network to go to space. The rocket will be launched roughly 200 miles above earth to test a new parachute-like technology called an exo-brake. Exo-brakes are used to safely return samples from the Earth’s orbit as well as land spacecrafts on other planets that have a much thinner atmosphere than Earth.

Typically the devices that collect samples are connected with wiring. The team chose to move away from traditional wiring and experiment with a wireless network for a number of reasons. For one, less cabling on the spacecraft means less weight, which reduces the amount of fuel needed. Another important feature is the ability to relay this data back down to earth via an Iridium satellite. The Soarex will monitor six different acceleration parameters as well as temperature and air pressure.

This wireless network is part of an effort by NASA to test the performance of wireless on a spacecraft and see if it will be suitable for other applications. Due to the high cost associated with launching a rocket, the team must be extremely conservative when implementing new technology into their rockets. Once the network has had multiple successful trials, the team will begin incorporating XBee into more and more vital missions.

When NASA chooses to experiment with new technology the initial budget is relatively small, so the engineers went with off-the-shelf components to build out the network. The team is working with Digi’s XBee ZB modules, Arduino microcontrollers, and Sparkfun’s XBee adapter shields.  If the trial run is a hit, they’ll work to build a more customized solution– one that might even feature the XBee Plus!

Soarex will launch with XBee in January 2015. We’ll share some more information and let you know how it goes, so check back in! Until then, check out this video to get an idea of the wild ride XBee will be taking.

A Simpler and More Intelligent Internet of Things with Digi and Temboo

Posted on: No Comments

The ongoing drought in the western United States underscores the importance of maintaining and conserving a reliable supply of fresh water—whether for drinking, irrigation, fire control or manufacturing, reliable water storage is essential. Of course, half the battle in maintaining a water supply is managing it: once a tank system has been installed and filled, water must be properly distributed when it is needed and retained when it is not. If tanks are remote and many are spread over a wide area, monitoring them can become a costly and time-consuming obligation.

Screen Shot 2014-09-04 at 12.03.09 PMThese are the sorts of challenges that Digi and Temboo are overcoming by building a more intelligent Internet of Things. A network of Digi hardware running Temboo Choreos is flexible and smart—devices can be programmed to execute a wide variety of processes, and be reprogrammed without being interrupted. This is a solution that combines ease of automation with the trustworthiness of manual control. To illustrate the solution’s benefits, and demonstrate how the whole system works, we’ve built a model of the water tank problem. This system puts Temboo and Digi to work, keeping water levels right where they ought to be.

Our tank monitoring solution uses an XBee ZigBee radio to wirelessly exchange sensor information and remote control commands using Digi’s new XBee Gateway, a programmable device that joins ZigBee mesh networks to the Internet. A small Temboo client written in Python is installed on the XBee Gateway, allowing it to connect to over one hundred different web services using Temboo Choreos. With Temboo, the memory constraints of the small devices in the network cease to be an obstacle to intelligent behavior, as much of the code required to execute complex processes is offloaded to the cloud.

In our model, a sensor attached to the XBee radio monitors the water level of our tank, and sends those readings to the XBee Gateway. If the tank leaks and the water level falls, a response is triggered on the gateway. First, the gateway uses Temboo’s Yahoo Weather Choreos to check the forecast for rain. Temboo’s Nexmo Choreos are then used to telephone the relevant individual with an automated voice message that gives a real time rain forecast and offers a choice of actions to take by entering a number on the phone’s keypad.

Screen Shot 2014-09-04 at 11.56.33 AMIf a storm is on its way, there is an option to ignore the alert. If the leakage does not need to be urgently addressed, there is an option to schedule a maintenance event for the future, which the Temboo program on the gateway handles via a Google Calendar Choreo . If the situation is urgent, however, there is another option to activate a backup pump at a different point in the XBee network and refill the tank.  Of course, all of this will only work properly if the sensor and gateway are powered on and functioning, so our system needs to be prepared for any loss of connectivity—if, for any reason, transmission of the level of water in the tank stops, another Temboo Choreo will file a Zendesk ticket to alert support that the system needs attention.

The most exciting thing about this model, however, is that it is only a small example of a massively scalable system. XBee technology can connect hundreds of different devices in a much larger network, and Temboo’s Library contains over two thousand other Choreos that can be used to execute an immense variety of tasks. Modifying the behavior of the Temboo program on the gateway to, for example, switch notification services is just a matter of changing Choreos, a simple task.  Digi’s hardware and Temboo’s software are coming together to build a lighter, smarter and much easier to use Internet of Things.

Bar Graphs, Security Systems, and GPS… All with XBee!

Posted on: No Comments

Here are a few more wireless projects you can build with some sensors, Arduino and XBee. Below are project descriptions and links to instructions that will walk you through each step, including example code. Feel free to get creative and put your own spin on these projects!

Wireless Bar Graph Display
Want to monitor the level of light in a room and reflect that data with a shiny LED bar graph? Then check out  this project, which uses an MBed microcontroller, light sensor, LED bar graph, and a pair of XBee radios to get you going on monitoring brightness without even being there. Complete instructions here.

Security Monitor
Let’s build a comprehensive security system! The motion sensor detects when a person passes by and alerts you by displaying a warning on an LCD screen and you can even be alerted with an audio message. For this project, you’ll need an Arduino and XBee radio. After all, Arduino and XBee are best friends in the electrical engineering world! Why else would an XBee shield exist? Complete instructions here.

Device Cloud GPS

Digi’s Annual Employee Golf Tournament: Wormburner 2014

It’s always nice to spend a day out of the office on a summer day and every July the competition starts to heat up around Digi. Teams are formed, enemies are made, and bragging rights for an entire year are put on the line– even friendly wagers involving car washes are involved.

It’s also a great opportunity for us to raise money and make an impact in our community by supporting charities like Fraser, Children’s Hospitals, Ronald McDonald House, and Treehouse. And good news, we have lots of pictures! Check ‘em out below.
