Battery powered IoT devices crucial to 2020+ standards

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-ready IoT devices based on ESP32

Battery / SuperCap power support allows the processes and data to be securely executed, saved or transferred, and the operating system to be safely shutdown or reboot, if the power source has been restored. The power failure alert can also be sent to cloud service, to perform custom task, specified by user or self-learning AI algorithm.

The Moduino device is a comprehensive end-point controller for variety of sensors located throughout any installation. It fully supports temperature and humidity sensors and new ones are currently developed, e.g. accelerometer, gyroscope, magnetometer, etc.

ModuinoModBerry symbiosis allows wide range of wake-up/sleep schedule customization, in order to perform best and save energy accordingly to power supply state. Arduino and MicroPython environments provide libraries to control different scenarios of data and power management.

With built-in algorithms and the possibility to program on your own, the TECHBASE’s sleep/wake addon module can wake the device using schedule/timer. Another option is wake on external trigger, e.g. change of input, etc. All the options for sleep, shutdown and wake can be configured for various scenarios to ensure constant operation of devices, safety of data and continuity of work in case of power failure in any installation.

ZigBee Mesh used in industrial IoT applications

ZigBee Mesh used in industrial IoT applications

ZigBee mesh‘s usefulness for IoT is partly due to the fact that it is an open standard. The same products can be used all over the world, which gives customers a large selection of available option. The high competition between products and producers means that the created solutions are innovative, characterized by high quality and give customers a considerable choice. Many suppliers of cooperating elements of this ecosystem mean that they are not limited to any specific brands or specific semiconductor manufacturers.

Competitiveness of ZigBee based solutions

With a maximum data bandwidth of 250 kbps at 2.4 GHz, ZigBee is slower than other popular wireless standards such as Wi-Fi or Bluetooth, but it doesn’t matter in typical sensor applications. ZigBee Mesh is designed to send small data packets at relatively long intervals, which is usually sufficient to collect data from temperature sensors, safety sensors, air quality monitoring systems and similar subsystems. In the meantime, the low bandwidth affects the low power needed for the system to work, so that ZigBee nodes can usually work for many years on a single AAA battery.

With low power consumption, ZigBee supporting products typically have a short transmission range – typically from 10 to 15 meters, and the signal they emit is easily disturbed by obstacles on the route, or changes in the environment. However, the beauty of ZigBee devices lies in their work as part of a lattice topology network, where each of them transmits signals between themselves over a total of longer distances. The grid topology also means that damage to a single device will not stop the entire network, as communication can simply be redirected.

Industrial use of ZigBee Mesh

One of industrial IoT devices, supporting ZigBee Mesh technology is eModGATE from TECHBASE. Economical, ESP32-based solution can serve as an end-point in any installation or works well as a gateway, gathering data from scattered sensor mesh across the installation. For more information check Industrial IoT Shop with all the configuration options for eModGATE, including ZigBee modem.

eSIM support for Rasperry Pi based ModBerry industrial device

The embedded SIM card (eSIM) is a form of programmable SIM card that is directly built in the device. eSIM is a global GSMA specification that enables remote SIM delivery to any supported device, and GSMA defines eSIM as the SIM card for the next generation of connected consumer / professional devices and network solution with the use of eSIM technology.

Easy SIM operator swap

In Industrial IoT applications in which there is no need to change the SIM card, the need of using a connector is avoided, which increases reliability and data security. eSIM can be remotely configured – users can add or change operators without having to physically swap the SIM card from the device. It is often a crucial requirement for the installations where factors such as temperature, water and shock resistance, as well as lack of access forces user to choose remote solutions.

ESP32 Serial Port

Arduino ESP32 Serial Port to TCP Converter via WiFi

In this class, you will create serial port to TCP converter using Arduino code running on ESP32 processor. We will use one of device which uses such processor: Moduino X ESP32. For TCP communication WiFi module will be used.

You will need:

  • Moduino X2 (may be also X1) ESP32 device (check this website to find out more)
  • PC with Linux operating system
  • socat application
  • RS-232/RS-485 port in your computer or USB to RS-232/RS-485 converter (for programmming and testing)

Introduction

In our example data sent to serial port (which is used as terminal port in regular Micropython ESP32 device) will be send via WiFi using TCP protocol. It also decodes incomming TCP packets and writes them to serial port.Then virtual serial port can be opened for that TCP packets and perform serial communication.We will use socat application for that.
