Here are a few of the many companies we are proud to work with.powerowners

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.

XBee Tech Tip: Digital IO Line Passing with XBee

Posted on:

A unique feature of the XBee 802.15.4 modules is the ability to perform digital I/O line passing. Essentially, this feature enables the user to toggle the state of any DIO pin on a transmitting radio and have that same pin on one or more receiving radios toggle their state to match the change. This functionality is an easy way to wirelessly control relays or any other switched equipment.

Note: DIO line passing can only be done with XBee 802.15.4 modules.wck_logo

Components used in this tutorial:

  • Two XBee 802.15.4 radios
  • Two XBee Grove Development Boards
  • Two Micro USB cables

To get started with this example, configure the pin of the XBee where the button is connected as digital input, and configure the pin of the XBee where the LED is connected as digital output. You will also need to configure the first XBee to send a notification to the other XBee when the button changes state.

Let’s get started.

Here are the configuration settings that need to be written to the XBee modules. In this example, XBee A is the transmitting radio and XBee B is the receiving module (click image to enlarge):

More of a visual learner? No worries. Follow along with this video as we write the parameters described above to both of our XBee radios.

Bonus Tip: Boost the reliability of the XBee connection by setting a sample rate on the transmitting XBee (Parameter: IR). If there happens to be interference while the data is being transmitted, it might not be received by XBee B. Setting a sample rate will ensure the change of state is communicated by the following sample rate packets.

Have the radios all set and ready to go? When the button connected to the the transmitting XBee is pressed, the LED of the receiver will light. Cue the drum roll….

If the application requires multiple receiver nodes, the change of state can be sent as a broadcast. To do this, modify the destination low address to “FFFF” on the transmitting radio. Note that this concept of DIO line passing is not specific to only pin 4, it can be applied to any DIO pin on the XBee 802.15.4 module.Wireless-Connectivity-Kit-DMG (1)

For this tutorial we used the new XBee Grove Development Board found in the Wireless Connectivity Kit. Visit Digi-Key to learn more about this new kit.

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

Posted on:

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.
