ONiO.zero running without battery can revolutionize the IoT market

ONiO, a Norwegian specialist in the field of the Internet of Things (IoT) for the medical industry, announced ONiO.zero, a RISC-V-based microcontroller with very low power consumption, which can work completely from the energy harvested from the environment. ONiO claims that its design can take energy from the radio spectrum and operate up to 24 MHz.

„ONiO.zero is a wireless MCU with very low power consumption, which uses energy acquisition technology,” wrote the company about its creation. This means that ONiO.zero only works on ambient energy. There are no coin cells, supercaps, lithium and batteries, but still offers a lot of performance.

Battery-based solutions have an unavoidable warning about battery replacement. This leads to increased costs over the entire lifetime. ONiO.zero avoids this problem and reduces operating costs. ONiO.zero is self-powered and supports a wide range of power sources, from multi-frequency RF bands supporting GSM and ISM to optional external sources such as solar, piezoelectric, thermal and voltaic.

NarrowBand-IoT the new black of Industrial IoT

The NB-IoT is becoming a standard in wireless communication of IoT devices, for standalone solutions and complex installations with thousands of units, coordinated with gateways. Will NarrowBand-IoT replace other wireless technologies in industrial automation?

What exactly is NarrowBand?

NarrowBand-IoT (NB-IoT) is a radio technology in the field of LPWAN (Low Power Wide Area Network) dedicated for IoT devices, operating on the licensed frequency band used by telecommunications operators.

The biggest advantages of NB-IoT include:

  • long battery life (up to 10 years),
  • efficiency in the amount of data transferred,
  • intra-building penetration,
  • the ability to connect even tens of thousands of devices in one system,
  • a global standard,
  • a high level of security and low cost

You can build mass solutions and those that until now were considered unprofitable. NB-IoT technology works in the licensed band, so there is no risk of interference and blocking communication by competing networks.

The service life of devices powered by two AA batteries is up to 10 years. However, the devices themselves are constructed in such a way that they can work for many years without the need for technical supervision and recharging the battery.

NB-IoT used in industrial solutions

One of many uses of NarrowBand-IoT wireless modems can be communication of edge devices, dedicated to data management, process control (e.g. with MQTT protocol) and monitoring. Latest ESP32-based eModGATE controller from TECHBASE company is a series utilizing MicroPython environment to provide data management solutions for end-points applications. The eModGATE has built-in Wi-Fi/BT modem and can be equipped with additional NarrowBand-IoT modems

IoT Security with latest SLM 9670 Industrial Grade TPM 2.0

Like other embedded systems, Industrial IoT design faces a constant stream of threats. As hackers adopt new attacks, developers rush to close security holes. Deployed devices need to update IoT firmware, increasing potential security vulnerabilities. For example, using a simple firmware verification check can leave the software published. In this situation, the developer may expect to be able to query external resources for verification and catch attempts to replace the firmware with hacked code. However, even relatively novice hackers can replace the firmware with code that ignores such verification checks. To secure these vurnerabilities comes Industrial Grade TPM 2.0.

Securing devices with Infineon industrial grade TPM

Infineon Technologies AG has unveiled a new security chip that defines the first TPM (Trusted Platform Module), designed specifically for industrial applications such as industrial computers, servers, industrial controllers and edge gates. The module protects confidential data in connected devices and reduces the risk of leakage of this information due to attacks, e.g. hackers.

The OPTIGA TPM SLM 9670 module protects the integrity of industrial systems and the identity of users using them. The system controls access to sensitive data at key locations in industrial environments, such as an automated factory. It also protects the cloud interface if the network uses one. The security system fully meets the TPM 2.0 standard developed by the Trusted Computing Group and is certified by an independent test laboratory in accordance with the criteria contained in this standard. The new module is meticulously controlled and certified by Infineon. Thanks to its use, it is possible to shorten the time of designing and introducing the device to the market, thanks to the ready security solution in the system.

The TPM system has a lifetime declared as 20 years. It allows programmers to perform firmware updates, which in turn enables them to meet the long-term security requirements in rapidly changing industrial environments. In this way, it can also reduce maintenance costs of industrial equipment thanks to secured remote software updates. The TPM chip will be available in serial production in the second half of 2019.

TECHBASE offers wide range of solutions, optionally aided with TPM system.

For example, ESP-32 based solution, Moduino X series and eModGATE series products offer the support for such security measures. Read more in Industrial IoT Ecosystem brochure, to understand the importance of reliable and secure hardware for Industrial IoT.

ESP32-based LoRa / LoRaWAN wireless network

One way of long-range and low-power data transmission is LoRa wireless technology. Since the Internet of Things market (with ESP32 – based solutions) is mainly covered with short-range Wi-Fi and Bluetooth and long-range with 3G / NarrowBand-IoT technologies, LoRa oftens is omitted or simply unknown by IoT users. Below you will find a short representation of what LoRa is and how can it be used.

What is LoRa / LoRAWAN network?

LoRaWAN® network architecture is deployed in a star-of-stars topology in which gateways relay messages between end-devices and a central network server. The gateways are connected to the network server via standard IP connections and act as a transparent bridge, simply converting RF packets to IP packets and vice versa. The wireless communication takes advantage of the Long Range characteristics of the LoRa physical layer, allowing a single-hop link between the end-device and one or many gateways. All modes are capable of bi-directional communication, and there is support for multicast addressing groups to make efficient use of spectrum during tasks such as Firmware Over-The-Air (FOTA) upgrades or other mass distribution messages.

Technology must transfer data to the central system in real time, otherwise it may have negative consequences. If the sensor battery power runs out, a machine failure may stop production for one day or lead to direct danger. If battery life is unbelievable and short, IoT applications will become useless, causing more interference rather than making life easier for its intended purpose. Therefore battery powered IoT devices come as a standard in up-to-date IoT installations

Wireless sensors and sensor networks are one of the elements of the Internet of Things systems and intelligent factories. Replacing the standard sensors and data collection devices with versions that communicate wirelessly gives many benefits, but also enforces a highly thought-out system design that will minimize energy consumption. This is important because these systems must work for many years without servicing. In the article we present the issues regarding the design of systems and forecasting of energy consumption in IoT systems.

Wireless communication vs Battery power

The idea of wireless sensor networks has been around for at least two decades, while the IEEE subgroup working on personal wireless networks defined the 802.15.4 standard in 2003, a year later the first versions of ZigBee appeared. Since then, many varieties of wireless communication have been developed, such as LoRa & NarrowBand-IoT and additional functions introduced, as a result of which designers now have a choice of various open or proprietary protocols. What significantly affects the way the entire project is implemented is energy consumption.

The basic elements of these systems are sensors that measure physical quantities. Some signal and data processing capabilities are also important. After all, the communication interface is important, which will allow you to pass the measured data on. Such a sensor node should wake up from time to time, make contact with its superordinate controller, transfer data and fall back to sleep again. Battery life depends on the total charge collected. Minimizing this consumption in the long run means that you need to minimize energy consumption during each work cycle. In many cases, the sensor will only work for a small fraction of the time. A measurement that lasts a few milliseconds can be triggered once per second, once per minute, or even less frequently. Therefore, the energy consumed in sleep mode may dominate the total energy consumption.

Battery powered sensors market growth

The lifetime of IoT sensors varies greatly: some last a year years, others 10, the first being the most realistic. When organizations need to deploy engineers to install new batteries in sensors and employ staff to monitor them, the benefits of technology itself are beginning to run out.

Battery powered IoT devices crucial to 2020+ standards

It is estimated that in 2020 nearly 31 billion devices will be connected to the Internet of Things. Such forecasts provide ample opportunities, especially for producers associated with the products that make up it, and they are intensified by the developing IoT technology.

The wM-Bus or Wireless Meter Bus is a European standard (EN 13757-4) that defines communication between usability meters and data loggers, hubs or intelligent meter gates. The M-Bus wireless bus has been developed as a standard to meet the needs of the European network of media meters and remote reading systems and forms the basis of a new advanced measurement infrastructure (AMI). The frequency of M-Bus and sub-GHz wireless connections has been used for several years, but is still evolving to adapt to changing environments and take advantage of technological advances, including the emergence of the Internet of Things.

COVID-19 and wireless technologies

In times of COVID-19 pandemic hazards, the use of wireless technologies is often a must, to prevent further spread of the coronavirus. One of obvious choices for Internet of Things and home monitorng is Wireless M-Bus implementation.

TECHBASE has added high performance module for Wireless M-Bus connectivity and multi-hop networking into Moduino series expansion options. The module is configured as an embedded micro system or simple data modem for low power applications in the metering specifically allocated band of 169 MHz or in the ISM band of 868 MHz. The device is can be configured for interoperability in a WMBus network for Industrial IoT applications.

2.4 GHz band vs unlicensed bands

Intelligent network devices require robust long-range wireless communication. The most common frequencies are around 868 MHz, 434 MHz and 169 MHz, which are unlicensed bands in Europe and offer better radio wave propagation compared to 2.4 GHz. By using one of these unlicensed bands, radio waves can reach difficult areas such as underground meters or the location of buildings with many walls or obstacles. Another advantage of operating in the unlicensed band is that utilities have lower solution costs.

The RF implementation guarantees best-in-class performance in terms of covered area and power consumption. The output power can be increased up to +30 dBm on the 169 MHz band (+27 dBm on optimized version for highest power efficiency) and up to +15 dBm on the 868 MHz band. The extremely reduced power consumption gives access to long lasting battery life requirement (up to 2 μA in sleep mode for wireless M-Bus module with an RTC clock running).

The Moduino devices  can be provided with a W-MBus stack specifically developed by Embit for the platform that allows to integrate the module in the desired system without effort and simplify the interaction in WMBus networks.
