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.

Raspberry Pi Compute Module 4

Raspberry Pi Compute Module 4 coming soon? Check possible specification.

It seems a matter of time before the Raspberry Pi Compute Module 3+ will get its own successor, probably called Compute Module 4, a new milestone of professional embedded IoT module

Possible Raspberry Pi Compute Module 4 specification

  • Broadcom BCM2711, Quad core Cortex-A72 @ 1.5GHz will highly plausible replace previous Broadcom BCM2837B0, Cortex-A53 64-bit SoC @ 1.2GHz,
  • 1GB, 2GB or 4GB LPDDR4-3200 SDRAM will become a standard options, instead of fixed 1GB LPDDR2 SDRAM,
  • Current flash memory (eMMC) options: 8GB / 16GB / 32GB from CM3+ will probably stay the same,
  • H.265 (4kp60 decode), H264 (1080p60 decode, 1080p30 encode) might replace outdated H.264 (1080p30),
  • and OpenGL ES 3.0 graphics will replace 1.1, 2.0 versions,
  • weight and factor will stay the same, to provide a possibility to upgrade current IoT applications of CM3 and CM3+

A Lite 4 version of Compute Module is to be expected too, without eMMC and probably limited SDRAM options.

Rasbperry Pi Compute Module 3+

ModBerry, the first Industrial Raspberry Pi application

With Compute Module 3+ options from Raspberry Pi, TECHBASE upgraded our ModBerry 500/9500 industrial computers. From now on the ModBerry 500/9500 can be supported with extended eMMC, up to 32GB. Higher memory volume brings new features available for ModBerry series.

Raspberry Pi 4 Model B

Updated M500 Industrial IoT device with latest Raspberry Pi 4

The newest addition to TECHBASE’s Industrial IoT Ecosystem is an updated ModBerry M500 with latest Raspberry Pi 4 development board, equipped with a 1.5GHz quad-core 64-bit ARM Cortex-A72 processor (approximately 3 times better performance than previous Cortex-A53 powering Raspberry Pi 3+ Model B and Compute Module 3 and 3+). ModBerry M500 can be configured from 1GB / 2GB / 4GB LPDDR4 SDRAM options.

Gigabit Ethernet & USB 3.0 on-board

Another new and appreciated feature is an upgrade to full-throughput Gigabit Ethernet for fast network connection and 2x USB 3.0 / 2x USB 2.0 for additional I/O, data storage extension and fast wireless modem support.

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.
