Nordic’s BLE SoC Selected for IIoT Energy Monitor Device

Nordic Semiconductor has announced that OneMeter, a Lublin, Poland-based Industrial Internet of Things (IIoT) startup, has selected Nordic’s nRF51822 Bluetooth Low Energy (Bluetooth LE) System-on-Chip (SoC) to provide the wireless connectivity for its “OneMeter Beacon”, a device that provides companies with the ability to monitor and manage their energy usage data in real time.

Designed for use in a broad range of industrial and commercial environments—for example production facilities, manufacturing plants, and food service companies—the OneMeter Beacon is simply plugged in to an existing electronic electricity meter via an optical port interface, enabling the beacon to receive energy usage data from the meter using the IEC 62056-21 / IEC 1107 protocol. Once installed, the beacon is paired to a Bluetooth 4.0 (and later) Android smartphone or tablet, where from the OneMeter app the user can initialize and synchronize the beacon.

Once synchronized, the beacon reads data from the meter every 15 minutes, and stores it in the Nordic SoC’s Flash memory, from where the beacon automatically transmits the data to the user’s smartphone or tablet using Bluetooth LE wireless connectivity provided by the nRF51822 SoC. From the app the user can review data from the most recent readout (including active and reactive energy consumption parameters), as well as view daily, weekly and monthly energy usage charts and more.

OneMeter Cloud provides a comprehensive platform from which a company can not only monitor its metering data, but also perform accurate energy usage cost estimation, conduct effective energy audits, avoid penalties for exceeding contracted power by defining power parameter alerts, as well as manage its photovoltaic (PV) infrastructure. Certified measurement data can be shared with energy vendors enabling invoices to be settled based on actual usage instead of forecasts. The OneMeter beacon is powered by a 3V CR2032 coin cell battery, providing up to 12 months battery life before replacement, thanks in part to the ultra-low power characteristics of the nRF51822 SoC which has been engineered to minimize power consumption.

Nordic’s nRF51822 is a multiprotocol SoC ideally suited for Bluetooth LE and 2.4GHz ultra low-power wireless applications. The nRF51822 is built around a 32-bit Arm Cortex M0 CPU, 2.4GHz multiprotocol radio, and 256kB/128kB Flash and 32kB/16kB RAM. The SoC is supplied with Nordic’s S130 SoftDevice, a Bluetooth 4.2 qualified concurrent multi-link protocol stack solution supporting simultaneous Central/Peripheral/Broadcaster/Observer role connections.

AI, FPGAs and EMBEDDED SUPERCOMPUTING

Embedded Supercomputing
Gone are the days when supercomputing levels of processing required a huge, rack-based systems in an air-conditioned room. Today, embedded processors, FPGAs and GPUs are able to do AI and machine learning kinds of operation, enable new types of local decision making in embedded systems. In this article, Circuit Cellar’s Editor-in-Chief, Jeff Child, looks at these technology and trends driving embedded supercomputing.

Convolutional Neural Networks in FPGAs
Deep learning using convolutional neural networks (CNNs) can offer a robust solution across a wide range of applications and market segments. In this article written for Microsemi, Ted Marena illustrates that, while GPUs can be used to implement CNNs, a better approach, especially in edge applications, is to use FPGAs that are aligned with the application’s specific accuracy and performance requirements as well as the available size, cost and power budget.

NOT-TO-BE-OVERLOOKED ENGINEERING ISSUES AND CHOICES

DC-DC Converters
DC-DC conversion products must juggle a lot of masters to push the limits in power density, voltage range and advanced filtering. Issues like the need to accommodate multi-voltage electronics, operate at wide temperature ranges and serve distributed system requirements all add up to some daunting design challenges. This Product Focus section updates readers on these technology trends and provides a product gallery of representative DC-DC converters.

Real Schematics (Part 1)
Our magazine readers know that each issue of Circuit Cellar has several circuit schematics replete with lots of resistors, capacitors, inductors and wiring. But those passive components don’t behave as expected under all circumstances. In this article, George Novacek takes a deep look at the way these components behave with respect to their operating frequency.

Do you speak JTAG?
While most engineers have heard of JTAG or have even used JTAG, there’s some interesting background and capabilities that are so well know. Robert Lacoste examines the history of JTAG and looks at clever ways to use it, for example, using a cheap JTAG probe to toggle pins on your design, or to read the status of a given I/O without writing a single line of code.

PUTTING THE INTERNET-OF-THINGS TO WORK

Industrial IoT Systems
The Industrial Internet-of-Things (IIoT) is a segment of IoT technology where more severe conditions change the game. Rugged gateways and IIoT edge modules comprise these systems where the extreme temperatures and high vibrations of the factory floor make for a demanding environment. Here, Circuit Cellar’s Editor-in-Chief, Jeff Child, looks at key technology and product drives in the IIoT space.

Internet of Things Security (Part 6)
Continuing on with his article series on IoT security, this time Bob Japenga returns to his efforts to craft a checklist to help us create more secure IoT devices. This time he looks at developing a checklist to evaluate the threats to an IoT device.

Applying WebRTC to the IoT
Web Real-time Communications (WebRTC) is an open-source project created by Google that facilitates peer-to-peer communication directly in the web browser and through mobile applications using application programming interfaces. In her article, Callstats.io’s Allie Mellen shows how IoT device communication can be made easy by using WebRTC. With WebRTC, developers can easily enable devices to communicate securely and reliably through video, audio or data transfer.

WI-FI AND BLUETOOTH IN ACTION

IoT Door Security System Uses Wi-Fi
Learn how three Cornell students, Norman Chen, Ram Vellanki and Giacomo Di Liberto, built an Internet connected door security system that grants the user wireless monitoring and control over the system through a web and mobile application. The article discusses the interfacing of a Microchip PIC32 MCU with the Internet and the application of IoT to a door security system.

Self-Navigating Robots Use BLE
Navigating indoors is a difficult but interesting problem. Learn how these two Cornell students, Jane Du and Jacob Glueck, used Received Signal Strength Indicator (RSSI) of Bluetooth Low Energy (BLE) 4.0 chips to enable wheeled, mobile robots to navigate towards a stationary base station. The robot detects its proximity to the station based on the strength of the signal and moves towards what it believes to be the signal source.

IN-DEPTH PROJECT ARTICLES WITH ALL THE DETAILS

Sun Tracking Project
Most solar panel arrays are either fixed-position, or have a limited field of movement. In this project article, Jeff Bachiochi set out to tackle the challenge of a sun tracking system that can move your solar array to wherever the sun is coming from. Jeff’s project is a closed-loop system using severs, opto encoders and the Microchip PIC18 microcontroller.

Designing a Display System for Embedded Use
In this project article, Aubrey Kagan takes us through the process of developing an embedded system user interface subsystem—including everything from display selection to GUI development to MCU control. For the project he chose a 7” Noritake GT800 LCD color display and a Cypress Semiconductor PSoC5LP MCU.

Compact, Arm-based Mini-PC is Toughened up for IIoT

By Eric Brown

DFI’s Pico-ITX-based, DIN-rail mountable “EC900-FS6” mini-PC runs Linux or Android on an i.MX6 DualLite, and offers 2x GbE, 2x USB, 2x serial, mini-PCIe, and extensive ruggedization features.

A reader recently noted our excessive use of the term “rugged,” which is fair enough. In our defense, embedded gear is increasingly tolerant of wide temperature ranges, and to a lesser extent, excessive shock, vibration, and dust and water ingress. From now on, we will no longer use “rugged” to describe a system that has a wide temperature range without also offering other protections. We will, however, continue to apply it to systems like DFI’s i.MX6-based EC900-FS6 mini-PC, which is not only rugged, but quite compact at 143 mm x 96.4 mmx 34 mm.

Designed for industrial IoT (IIoT) gateways and other embedded applications, the EC900-FS6 features -20 to 60°C or -40 to 70°C support, as well as 3G, 11ms shock resistance and IEC68-2-64 (3G) compliant vibration resistance (random 5~500Hz). It also has a 10 to 90% RH (non-condensing) humidity range and provides a wide-range 9-36V DC input via a terminal block. The fanless, DIN-rail mountable system has a 15-year lifecycle guarantee.

The EC900-FS6 is built around DFI’s Pico-ITX form-factor FS053 SBC, which is equipped with a dual Cortex-A9 i.MX6 DualLite SoC clocked to 1GHz. Both the SBC and the system ship with Android 5.1 beta, as well as a stack built with Yocto Project 1.8 beta, both with Linux Kernel 3.14.52.
