ESP32-based devices with 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.

Industrial use of LoRa & ESP32-based solutions

One of industrial IoT devices, supporting LoRa wireless technology is ESP32 based 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 and also Raspberry Pi based solutions check Industrial IoT Shop with all the configuration options for eModGATE.

Arduino-aided ModBerry 500-CM4 with ESP32 for power management

Sleep functionality for ModBerry 500 CM4 devices

TECHBASE company designed an extended version of Raspberry Pi Compute Module 4 based devices, ModBerry 500-CM4-PM series for better power management in changing conditions of industrial applications. With the use of GPIO the module can manage boot, sleep mode or safe shutdown of the device in terms of unexpected drop in the power network with help of built-in ESP32 module and Arduino environment.

In the last few years developers marketed a wide range of ARM-based development boards, lacking in enhanced power management, especially sleep and wake up modes, commonly used in PC-grade computing. These boards are not adjusted for battery power supply, so it’s natural that sleep/wake functions should be implemented. In connection with the development of solutions based on Linux-SBC, key factor is adding sleep modes to any remote installation

ESP32 based addon module for Raspberry Pi

With built-in algorithms and the possibility to program on your own, the TECHBASE’s sleep/wake addon module can wake the device using a scheduler/timer. The module itself is based on ESP32-WROVER, used in the Moduino X series. ESP32 as a lightweight and low-powered solution is a perfect aid system for Raspberry Pi. Another option is wake on external triggers, e.g. change of input state, 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.

Sleep mode with additional power backup

Additional power management option for ModBerry devices is sleep functionality enhanced with SuperCap UPS energy backup device. This solution allows programming scenarios including the execution of chosen actions, in order to save data, send a notification and restart/shutdown the controller after completion.

Advanced power management solution

Most advanced configuration includes use of ESP32 module, known from the successful, lightweight Moduino X series, for extra logic for wake up / sleep scripts. This addon will allow the RaspberryPi-based ModBerry device to be woken up by the internal ESP32 controller

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

ModBerry 500-CM4-PM availability

The preliminary ModBerry 500-CM4-PM devices are available on request and delivery time will be specified by the Sales Dept. depending on the size of the project. Contact via email or Live Chat here: https://iiot-shop.com/

IoT device built on ESP32 module and NarrowBand-IoT wireless technology

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

eModGATE with ESP32

eModGATE eqipped with wireless NB-IoT modem are perfect for industrial automation solutions, e.g. data logging, metering, telemetrics, remote monitoring, security and data management through all Industrial IoT applications.

Supported bandwidths:

  • Global-Band LTE CAT-M1:  B1/B2/B3/B4/B5/B8/B12/B13/B18/B19/B20/B26/B28/B39;
  • Global-Band LTE CAT NB-IoT1:  B1/B2/B3/B5/B8/B12/B13/B17/B18/B19/B20/B26/B28;
  • GPRS/EDGE 850/900/1800/1900Mhz Control Via AT Commands

Supported data transfer:

  • LTE CAT-M1(eMTC) – Uplink up to 375kbps, Downlink up to 300kbps
  • NB-IoT – Uplink up to 66kbps, Downlink up to 34kbps
  • EDGE Class – Uplink up to 236.8Kbps, Downlink up to 236.8Kbps
  • GPRS – Uplink up to 85.6Kbps, Downlink up to 85.6Kbps

Industrial Raspberry Pi with LoRa support is a must

As the remote application market is growing rapidly, technology also needs to progress, ensuring greater range and transmission speed while reducing energy consumption. Technological progress makes it possible to create innovative standards for new, sophisticated applications that facilitate our life and work. One of wireless connection choices can be LoRa technogoly.

What exactly is LoRaWAN?

LoRa (Long Range Radio) technology with low data throughput allows IoT and M2M applications to communicate wirelessly over 15 kilometers, with a battery life of more than 10 years. LoRa allows you to connect millions of wireless nodes with compatible gateways and has several key advantages over other wireless solutions. For example, it uses spectrum spreading modulation with the ability to demodulate a signal 20 dB below the noise level.

LoRa uses license-free sub-gigahertz radio frequency bands like 433 MHz, 868 MHz (Europe) and 915 MHz (Australia and North America). LoRa enables long-range transmissions (more than 10 km in rural areas) with low power consumption.[4] The technology is presented in two parts: LoRa, the physical layer and LoRaWAN (Long Range Wide Area Network), the upper layers.

Source: https://en.wikipedia.org/wiki/LoRa

Compared to 3G and 4G cellular networks, LoRa technology is also better scalable and more cost-effective for embedded applications. It has a much greater range than other popular wireless protocols, which allows devices to operate without amplifiers, reducing the total cost of the application.

Thanks to scalability, reliable communication, mobility and ability to work in difficult external conditions, the LoRa module is perfectly suited for use in a wide range of wireless monitoring and control applications that do not require high transmission speeds. Examples of applications may include smart city (street lighting sensors, motion sensors), energy (intelligent measurement of electricity / water / gas consumption) and industrial / commercial / home applications, among others HVAC, intelligent devices, security systems and lighting.

Use of LoRa in industrial automation

Use of wireless connection makes life and work easier for us every day – from radio stations and GSM to Wi-Fi wireless networks, Zigbee, short-range Bluetooth connectivity and LoRa. With the spread of internet access, the possibility of using wireless connectivity for a new type of service and application has opened. Terminology such as M2M (Machine to Machine) – remote communication between devices and IoT – a network of applications and devices communicating with the Internet have been created.

Device equipped with LoRa module is delivered with a LoRaWAN protocol stack, so it can be easily connected to the existing, fast-growing LoRa Alliance infrastructure – both in privately managed local area networks (LAN) and public telecommunications networks to create wide area low power WAN (LPWAN) on a national scale. LoRaWAN stack integration also allows connection to any microcontroller, such as LoRa Gateway from TECHBASE.

New features of multiple Compute Modules 4 brought to new ClusBerry series

Accompanying the release of ModBerry 500-CM4 and AI GATEWAY 9500-CM4, we present to you a cluster version of the device, called ClusBerry 9500-CM4. Main difference between standard Gateway and ClusBerry is the possibility to include multiple Compute Module 4 in one device, as well as the intended suitable amount of wired and wireless interfaces, suited for the project.

Fully configurable devices are something desirable in the IoT market, where high performance and low cost is a key factor to success of implementation. TECHBASE’s Industrial IoT Ecosystem gives the opportunity to adjust ordered devices with certain resources and cut unnecessary I/Os, lowering the total cost of the device.

For this purpose, the arrays of processor blocks are constructed to be assigned to individual tasks. For several years now, attempts have been made to use various types of SBC for this purpose, including, of course, Raspberry Pi. However, the practical effectiveness of such solutions so far has not been of interest for several reasons. First of all, these solutions were most often associated with many mechanical limitations and the structure of the matrix itself required excessive wiring, preventing failure-free operation and the cost of the entire maintenance of the structure.

Raspberry Pi Compute Module 4 Cluster

This is where Raspberry Pi Compute Module can shine, but due to the hardware speed limitations of the buses in this module, it was not completely effective and was rather a development platform. Altho the introduction of new Compute Module 4 has opened the possibility to construct and maintain effective hardware matrix solutions with the use of both PCI-Express buses and 1GBps Ethernet. Therefore, the ClusBerry 9500-CM4 opens up completely new capabilities of utilizing cluster solutions for Industrial Automation and server applications.
