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.

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.

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.

Symbiosis of RaspberryPi and ESP32 in one device

The latest configuration of ModBerry 500 device presents the important milestone in TECHBASE’s offer. The introduction of two platform symbiosis, RaspberryPi Compute Module 3 assisted with Espressif’s ESP32 module brings new possibilities of application to life. High performance of CM3, if compromised by exposition to harsh environmental conditions or sudden drop of power, is aided with low-powered ESP32’s real-time system to continue operation of the device. ESP32 module can be battery powered, same as standalone Moduino series, based on similar solution.

ESP32 subsystem for ModBerry 500

Main difference between ESP32-aided ModBerry device and ESP32-based Moduino is that the first one benefits from low-power module aid to prevent errors and downtimes. ESP32 compared to Compute Module 3 works much longer on battery power supply and offers extended sleep modes. Real-time system of ESP32 and simplified communication between ESP32-aided ModBerry device and Moduino controllers drastically shortens the time needed for the system implementation and the cost of maintaining the application. It also enables the use of Espressif’s Wi-Fi-based technology in the ESP-NOW and ESP-MESH networks.

The separate ModBerry-Moduino Ecosystem, working as a separate devices is a solution for scattered object and installations monitoring – with the use of wireless communication interfaces (e.g. LoRa, NarrowBand-IoT, ZigBee, Wi-Fi, Bluetooth, etc.), rather than standard wired networks. For more information ask TECHBASE via one of contact form at: https://modberry.techbase.eu/ & http://moduino.techbase.eu/

Coming soon

TECHBASE plans further development of the product, particularly the issue of remote access to input/output resources and use of ESP32 as a Security Chip – hardware layer protection against hacking (very important issue in current IoT business).

 

ModBerry brings Compute Module 3 to next level of Industrial IoT

Introduced with Moduino series, TECHBASE developed further the project of modular aluminum case for their devices. The latest version of housing allows ModBerry to expand in any dimension, supporting additional extension cards (e.g. I/Os, modems, opto-isolation, accelerometer, etc.) and DIN rail mount, that can be retracted into device itself. TECHBASE constantly improves the project to support different platforms (e.g. Raspberry Pi Compute Module 3, NanoPi, ESP32, UpBoard and probably more in the nearest future) and brings them to Industrial IoT world.

Supercapacitor power support for ModBerry

To improve the possibilities of ModBerry devices, TECHBASE added supercapacitor UPS option for ModBerry 500 configurations. Additional power supply available at emergency situations, such as power drop or loss, allows the device to log the recently acquired data and send the notifications to user regarding the occurred event. The supercap support for ModBerry ensures safe system shutdown and protects memory from fragmenting, so there is no need to use diagnostic tools afterwards.

ModBerry enhanced with OLED screen

Just like ESP32-based Moduino series, the ModBerry computers can be now equipped with OLED 0.96″ 128×64 screen via i2c extension protocol. The is small, only about 1″ diameter, but very readable due to the high contrast of an OLED display. Because the display makes its own light, no backlight is required, therefore reduces the power required to run the OLED.
