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.

How to Meet Critical Infrastructure Requirements with Cellular Devices

Posted on: No Comments

Critical infrastructure operations–whether it be an electrical substation, wastewater treatment plant, or traffic control center–are relying more and more on networked assets like sensors and control switches. But, the introduction of connected devices also raises security risks. Since these systems control services both businesses and consumers heavily depend upon, regulations are in place to ensure our infrastructure remains in working order and secure from threats.

Much like the laws you abide by while driving such as wearing your seatbelt, staying within the speed limit, etc., utility providers connecting assets with cellular LTE must follow certain standards and protocols to ensure security and reliability. In North America, these rules and standards are referred to as North American Electric Reliability Corporation Critical Infrastructure Protection or more conveniently as NERC-CIP. For our friends in Europe, the standard is called “European Programme for Critical Infrastructure Protection” or EPCIP for short.

What makes a network solution NERC-CIP compliant? In this video, Brad Cole, Device Cloud Product Manager, walks through the steps many of our utility customers take in order to deploy secure and connected critical infrastructure.

In short, critical infrastructure operators must comply with these reliability standards–or face large penalties. The mandatory Reliability Standards include CIP standards 001 through 009 (see below), which address the security of cyber assets essential to the reliable operation of the electric grid.

  • CIP-001: Covers sabotage reporting;
  • CIP-002: Requires the identification and documentation of the Critical Cyber Assets associated with the Critical Assets that support the reliable operation of the Bulk Electric System;
  • CIP-003: Requires that responsible entities have minimum security management controls in place to protect Critical Cyber Assets;
  • CIP-004: Requires that personnel with authorized cyber or unescorted physical access to Critical Cyber Assets, including contractors and service vendors, have an appropriate level of personnel risk assessment, training, and security awareness;
  • CIP-005: Requires the identification and protection of the Electronic Security Perimeters inside which all Critical Cyber Assets reside, as well as all access points on the perimeter;
  • CIP-006: Addresses implementation of a physical security program for the protection of Critical Cyber Assets;
  • CIP-007: Requires responsible entities to define methods, processes, and procedures for securing those systems determined to be Critical Cyber Assets, as well as the other (non-critical) Cyber Assets within the Electronic Security Perimeters;
  • CIP-008: Ensures the identification, classification, response, and reporting of cybersecurity incidents related to Critical Cyber Assets; and
  • CIP-009: Ensures that recovery plans are put in place for Critical Cyber Assets and that these plans follow established business continuity and disaster recovery techniques and practices.

The Digi TransPort WR31 comes with features and configuration options to simplify securing critical infrastructure assets like electric and gas meters or traffic control cameras. The Digital I/O can address physical security concerns and Remote Manager will log user information and even device changes.

Owlet Nightshift by Schreder | Connected LightingRoundabout at twilight
As cities deploy LED street lights to cut energy costs, they’re also turning to wireless technology for data collection and remote monitoring for their street lighting.

Utilizing Digi wireless technology, Schréder developed the Owlet lighting solution, which enables cities to retrofit out-of-date lighting infrastructure with long lasting intelligent technology. Within each light is an LED array along with a Digi XBee ZigBee module. The XBee radios create ZigBee mesh network-connecting all of the city’s street lights wirelessly. Data from each light is then sent to a single point, a cellular XBee Gateway, which then  connects to a cellular network.

The XBee Gateway allows the city to monitor and control lighting with Owlet’s web-based management tools. Also, municipalities don’t have to wait for a citizen to report an outage or check lights via scheduled inspections. The lights themselves can tell the city when they need to be serviced or replaced.

Wireless Technology Driving Business Transformation in the Oil & Gas Industry

Posted on:

As the demand for oil and gas increases, reduction in operating and maintenance costs and an increase in reliability are top priorities for the industry. However, that is easier said than done when you’re talking about assets deployed in harsh environmental conditions and widespread, remote locations. Even minutes of production downtime can result in hundreds of thousands of dollars lost. Ensuring that production machinery and other critical equipment downtime is minimized not only reduces operating and maintenance costs, but also increases production revenue and improves worker safety.Screen Shot 2015-04-02 at 12.29.50 PM

Oil and gas companies will benefit by moving away from a reactive analog maintenance model where action isn’t taken until a field operations team arrives at the location and identifies the asset is no longer functioning, resulting in unplanned downtime and lost revenue. Many companies have migrated to a proactive (scheduled) maintenance model, which is characterized by maintenance being performed at manufacturer-recommended intervals. This philosophy is actually the most expensive to follow because components could be unnecessarily overhauled or replaced. In addition, assets can and will still fail between maintenance cycles.

preventative maintenance model on the other hand, brings assets and data into business operations to enable companies to remotely monitor, control and identify problems. Being able to predict failures and maintenance requirements, you can better forecast and schedule maintenance activities, which reduces operational and maintenance costs.

With our XLR Pro long-range wireless radios, industrial grade Transport WR21 cellular routers and Digi Remote Manger, companies can quickly deploy a comprehensive global connectivity model today. You can seamlessly connect your assets, gather and integrate data to better control those assets, and remotely manage the network devices for security compliance and system updating. This kind of solution results in:

  • Connected assets and their data have increased visibility across an entire organization.
  • A proactive approach to maintenance whereby issues are resolved before they even occur
  • Field service operations teams are empowered by a rich set of device data and information to begin troubleshooting issues. This includes not only the real-time status of mission critical equipment, but also historical data points for trending and long term analysis
  • Deployments and truck rolls are made on a needs-based approach, which manages costs more effectively and positively impacts the bottom-line.

Australian Researchers Improve IEQ with ZigBee Based Sensor System

Posted on:

As the cost of energy rises and environmental concerns move us toward new sources of energy, how do we ensure we make the most out of every watt? There are a number of companies and organizations emerging to address this truly global issue.

University of Sydney Indoor Environmental Quality (IEQ) researchers Tom and Alex Parkinson, built SAMBA to help solve the balancing act between comfort and reducing energy consumption. SAMBA is a platform comprised of remote sensors deployed throughout commercial office environments and a web interface for data visualization. The system collects data points — enabling building managers to improve IEQ and save costs.

The platform is made possible by wireless technologies like ZigBee mesh networking and cellular data communications. Additionally, recent advancements in sensor technology have made it possible to create sensor nodes capable of measuring a variety of parameters, while maintaining a small form factor and remaining affordable.

 

How SAMBA Works
Within each node you’ll find sensors to monitor thermal comfort, acoustics, lighting, and indoor air quality. Processing at each node is handled by an ATmega328 chip running an Arduino sketch. A cool feature of the node is a flash memory chip. This helps prevent any data loss in case there’s a network failure by allowing data to be stored locally. Once the data is collected it hops from XBee to XBee until it reaches the central hub. Data is sent from each node at an interval of once every 5 minutes.

The central hub/cellular gateway is currently a Raspberry Pi with a cellular module. The gateway does some minor processing before sending data over the cellular network to SAMBA’s server. Due to the mesh networking capabilities of the sensor nodes, it is possible to just have one central hub per building. This makes the solution extremely cost efficient. As the team works to take this to production and scale their operation, they’re evaluating replacing the Raspberry Pi with the XBee Gateway.

Why ZigBee
The development team chose to use ZigBee for a multiple reasons. For one, the mesh networking capability makes the deployment of nodes more flexible and, in many cases, only one central hub is needed per building. Another factor was the development tools at their disposal like the open source Arduino library for the XBee ZigBee Radios. You can access that library here. This library helped them to cut down development time significantly.

The SAMBA crew is already getting some nice recognition throughout Australia. Just last week, Green Cities included them on their list of Weapons of Mass Creation! To learn more about the University of Sydney’s Indoor Air Quality Lab, click here visit their site.

How We Built a 4G LTE Connected Digital Signage Solution

Posted on:

We’re getting settled back in after an eventful few days at Digital Signage Expo. It was our first time at the event and we had a blast! Here at Digi, we mainly focus on the connectivity side of things whether it’s RF modules or a cellular router– that’s our expertise. But, in a digital signage solution, there are so many elements that come into play.

For this special event, we wanted to make sure we had a digital signage demo ready to go and we didn’t have much time to put it together. With some extremely helpful advice and easy-to-use tools we were able to get it up and running in less than a week (thanks to Amazon Prime overnight shipping).

PeerlessandAndrew (2)

How We Did It
Here are the basic elements of the demo. First we needed an enclosure– something that we could mount a big ol’ monitor to. Our friends at Peerless-AV hooked us up. Their kiosk gave us an enclosure for not only the screen, but also the mini PC, TransPort cellular router, and other accessories like antennas and power supplies.

Screen Shot 2015-02-25 at 2.08.33 PM

So now that we had all the gear hooked up and ready to go, we needed to figure out what we wanted to display on the screen. Screenfeed paid us a visit and set us up with some live RSS feeds.

These feeds allow us to send out fresh, new content to the display. Specifically, we had live financial data, major headlines of the day, and most importantly…weather updates. Another crucial aspect of serving up content to our display was the software to manage the images and RSS feeds.

Using our Wondersign free trial we plugged in our RSS feeds and .jpgs and had our screen displaying content in under an hour. Here’s a quick video that walks you through the display live on the DSE show floor!


There are many distinct advantages of delivering content via 4G LTE. For one, you get a high bandwidth connection that doesn’t need existing infrastructure like Ethernet or Wi-Fi, which offers the flexibility to deploy signage anywhere with network coverage. 4G LTE also provides a secure connection and the ability to easily manage a large deployment of devices via the cloud. This is just a demo, but many of Digi’s customers have realized the value of cellular connected signage. Learn how Monster Media is using cellular technology out in the field.
