PowerOwners | Solar Energy

How do solar energy providers  measure the effectiveness of their solar panel deployments? You’ll probably get a wide variety of answers depending on who you ask. PowerOwners saw this inconsistency in the solar industry as an opportunity to create a standard benchmark to measure the performance of solar assets.

The centerpiece of the system is the Deno Smart Sensor. The sensor measures sunlight and temperature to simulate an energy benchmark. It’s placed alongside solar panels, the Deno Smart Sensor is pictured to the right. Data is transmitted wirelessly by a Digi XBee PRO 900HP and collected within Digi Device Cloud. This service replaces the commonly used weather stations, which were difficult to deploy and provided inconsistent data. Read the full story here.

Why You Should Choose Cellular for Your IoT Solution

Posted on:

You already know how ubiquitous cellular is, but did you realize it’s going above and beyond the device you have in your hand? Lower costs and reliable connections are driving cellular adoption in M2M and Internet of Things applications. According to Berg Insights, there are already around 187 million cellular connected M2M devices. Here are some of the top reasons our customers choose to go with a cellular solution for their M2M and IoT solutions.

Screen Shot 2015-05-08 at 9.53.59 AM
1. Ubiquitous Coverage
Cellular coverage is nearly everywhere. A recent ITU report suggests that the total number of global mobile subscriptions is approximately 6.8 billion – nearly the same as the estimated world population.

Cellular devices can be deployed anywhere that is in network coverage.  It can also be deployed in mobile applications where devices need to stay connected no matter where they are at (e.g. fleet/asset tracking), even across wide geographical areas.  Additionally, there is a growing population of picocell deployments that are enabling improved in-building coverage for shopping centers, large corporate buildings, subway stations, etc.

2. Easy Deployment
Cellular devices can be pre-provisioned by distributors or system integrators before shipment to the end-customer, so they connect to the network right out of the box.   No end user provisioning is required (e.g. setting up security to connect to a Wi-Fi access point)

Cellular devices are not dependent on IT infrastructure (e.g. Wi-Fi access point, corporate Ethernet, …).  Deploying Wi-Fi or Ethernet connected devices inside environments like hospitals or shopping centers can be difficult due to IT teams not allowing 3rd party devices on their network.  What if the IT network is updated or security settings change? Cellular connected devices ensure you retain complete control over your device.

3. Lower Support Costs
With cellular, the infrastructure is owned and managed by the cellular carriers, not the end-customer or product supplier.  This means no upfront infrastructure costs and reduced support costs. Because cellular connectivity does not depend on end-user managed infrastructure (Wi-Fi, ZigBee, etc.), product suppliers do not have to provide ‘helpdesk’ support services for basic connectivity issues (e.g. “My device won’t connect to the access point.  The security settings are not working….”).  Instead of deploying your own infrastructure, leverage one of the world’s largest communication infrastructures – the cellular network.

4. Improved Reliability
Reliability is critical for many M2M applications, especially those involving security and real-time monitoring and alerts.  With cellular, you are leveraging a robust wireless network used by nearly 1/3 of the world’s population every day.  Cellular network outages are rare and if they do occur they are immediately noticed and acted on.  Consider a less reliable alternative — a device is connected to a consumer-grade Wi-Fi access point, maintained by the store clerk in a small gas station.  If the wireless connection fails, it could go unnoticed for extended periods of time and require manual intervention to resolve.

5. Lower Hardware Costs
Cellular module costs have fallen significantly in recent years. High-volume pricing for data-only modules is approaching sub-$10 for 2G GSM, sub-$20 for CDMA 1xRTT and sub-$30 for 3G UMTS. These price points are enabling a whole new class of devices and applications.

6. Lower Data Costsgodzilla
Data costs have also fallen significantly.  For connected machines that only need to report small amounts of data, connectivity costs can be <$1/month.  A vending machines that reports daily inventory clearly doesn’t need the same costly data plan as a consumer streaming HD music videos.

7. No Risk of Inflatable Godzilla Ruining Your Network
This isn’t a joke. One of our own customers has run into this problem. VSAT requires a satellite typically placed on the top of the building. But what happens when the store manager requests an employee go to the roof and tie up a giant inflatable Godzilla? The store employee probably isn’t a wireless communications expert and decides to use the satellite to anchor Godzilla. This can pull the satellite out of the direction it requires to connect — resulting in costly downtime.

Obviously this isn’t an epidemic, but with cellular you don’t need to worry about the direction your antenna is pointed.

Many of our customers are realizing the value provided by cellular connected devices today. In addition to providing a secure and reliable connection, it enables them to manage and monitor their network from anywhere. Here’s an example of how our customer, Monster Media, is using cellular to connect and manage digital signage around the world.

City of Visalia Upgrades Public Transit with Verizon 4G LTE

Posted on:

The city of Visalia had a cellular solution for their public transit system but it was built on a 2G network.  As 2G networks are slowly phased out over the next few years, coverage is becoming increasingly inconsistent.

With the impending shut down of 2G, Visalia needed a way to modernize their public transit system. They worked with Digi to deploy the TransPort WR44 R throughout their fleet of public transit buses, in order to provide their buses with high speed, 4G LTE connectivity.

This rugged cellular router connected over Verizon’s 4G LTE network provides multiple benefits to the city’s public transit system:

  • Security and safety with access to live video from the bus
  • Ability to offer value added services like free Wi-Fi to passengers
  • Reliable and secure connection to process ticket sales

In one month, customers downloaded roughly 540 GB of data across the entire fleet and an estimated 3,200-3,500 passengers accessed the free Wi-Fi. Overall, a reliable and high-speed cellular connection provides the heartbeat for the entire transit system and is guaranteed to last for years to come.

Customer Showcase: Wireless Technologies Create Foundation for Disruptive Businesses

Posted on:

Every day Digi works with customers around the world to deploy connected device solutions. Businesses across a variety of industries are realizing the value provided by internet connected assets. From the ability to monitor device health to delivering media relevant to a local audience, connected devices are modernizing business operations. Here are a few of the many companies we are proud to work with.

Monster Media
Digital Signage is a rapidly growing industry as 4G LTE becomes more prevalent and consumers expect a more interactive experience with signage and digital displays.  Monster Media is a leader in this relatively new industry. The company specializes in delivering dynamic and interactive media to high traffic venues like college campuses, conferences, sporting events, and much more.Screen Shot 2015-04-03 at 12.47.38 PM

The team was in need of a quick and simple way to connect their digital displays to the Internet in order to provide relevant and fresh content out to the world. Cellular connectivity was an obvious solution due to its the ease of deployment. Wi-Fi is another popular solution for digital signage, but often adds complexity due to coordinating with local IT as well as taking on additional security-related risks. Cellular connectivity also makes mobile assets a non-issue since no cabling is required and zero dependence on other infrastructure. With these advantages in mind, Digi TransPort WR21s are now found inside each of Monster Media’s kiosk providing a secure and reliable cellular connection

In addition to a reliable connection for delivering content, Monster Media is able to use the Digi Remote Manger for updating device configurations and firmware from the company’s NOC.

US Water
US Water provides a variety of engineering services, equipment, and field services. To enhance their offering and further differentiate themselves from larger water treatment firms, the company wanted an advanced monitoring solution that could reduce operation costs and enable their field service team to focus on high value tasks.css-thumbnail-us-water

Utilizing XBee ZigBee Modules and cellular connected gateways, their remotely connected sites give U.S. Water an easy way to monitor customers’ usage of chemicals, tank levels, and additional insight into their supply chain. Digi also partnered with Verizon to create a data strategy that made sense for their business.

Clean Hand Safe Hands 
Washing hands is one of the simplest and easiest ways to reduce the spread of disease. According to the CDC, in 2011 there were 721,800 hospital-acquired infections. Clean Hands Safe Hands saw this as opportunity and created a wireless system to remind hospital employees to clean their hands.chsh-logo-300x118

The entire system is made possible by a combination of three wireless technologies: ZigBee, Bluetooth, and Cellular. Employees’ badge reels are Bluetooth-enabled so the hand sanitizer dispensers can record when hands are washed. The dispensers are all connected by a ZigBee mesh network and data is sent to a single cellular take out point via the XBee Gateway.

The XBee Gateway enables cloud connectivity, so hospitals can easily generate reports on their compliance and remotely monitor devices.

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.
