The Future of Asset Tracking: IoT at Scale with LTE-M technology

IoT tracking at scale LTE-M technology

CNXSoft: This is a guest post by Ohad Peled, Product Marketing Manager at Sony Semiconductor Israel, about the challenges of tracking a large number of IoT assets and how LTE-M can help businesses scale tracking solutions. Over the last few years, asset tracking has emerged as a critical business function and is estimated to grow to a $34.5B market by 2032, according to Custom Market Insights. Whether businesses are monitoring a global supply chain or keeping tabs on expensive equipment, knowing where assets are at all times is essential. It enables businesses to optimize supply chains, prevent theft, and reduce operational downtime. There are several technical and commercial challenges in deploying such a solution, which could result in failure to deliver the promised value. Some solutions struggle to maintain accurate tracking as assets move within or across different facilities, especially if they go through an indoor environment. Others suffer from […]

Dual-channel LoRaWAN AC energy meter features 10A/100A CT clamps, measures temperature and humidity

AgroSense 2 Channel LoRaWAN AC Current Monitor

The AgroSense AGLW2CT is a dual-channel LoRaWAN-based industrial AC energy meter that utilizes 10A and 100A CT clamps to measure power consumption non-invasively. The device features two 0–5V analog inputs for the clamps, an AHT20 temperature & humidity sensor, and local storage for 3,300+ records. It supports LoRaWAN 1.0.3 OTAA Class C and works with TTN, Datacake, and CloudStudio. The device operates within the -40°C to 85°C industrial temperature range and is suitable for contactless current sensing, overload/no-load detection, and machine health monitoring. We had previously covered, and even reviewed, several Wi-Fi-connected CT clamps meters such as the MachineQ’s MQpower CT, Seeed Studio’s XIAO-2CH-EM, and Emporia’s Vue Gen 2 energy monitor, but it’s the first time we’ve come across a LoRa AC energy meter with CT clamps. Earlier this month, we noticed the MOKO LW005-MP LoRaWAN Smart Plug and power meter, but it relies on direct AC power measurements and […]

$6.5 RAK11160 LoRaWAN, WiFi, and BLE module pairs ESP32-C2 with STM32WLE5 for low-power, long-range IoT

RAK11160 ESP32-C2 STM32WL LoRaWAN module

RAKwireless RAK11160 is a new low-cost, low-power LoRaWAN, WiFi 4, and Bluetooth LE module based on ESP32-C2 (ESP8684) wireless microcontroller and STM32WLE5 LoRa SoC for LPWAN IoT applications. The company noticed that many people would combine their STMicro STM32WL-based RAK3172 WisDuo LoRaWAN module with an ESP32 module to add WiFi and/or Bluetooth connectivity to their projects besides LoRaWAN. So RAKwireless decided to offer a module combining both STM32WL and ESP32-C2 to offer a cheap and much more compact solution to their customers. RAK1160 was born. RAwireless RAK11160 specifications: LPWAN SoC/SiP – STMicro STM32WLE5 Core – Arm Cortex-M4 MCU @ 48 MHz Memory – 64 KB RAM Storage – 256 KB flash memory with ECC Wireless  – Sub-GHz radio based on Semtech SX126x LoRaWAN 1.0.4 specification compliant Supported bands – EU433, CN470, IN865, EU868, AU915, US915, KR920, RU864, and AS923 LoRaWAN Activation by OTAA/ABP LoRa Point-to-Point (P2P) communication Tx Power Output – […]

ThinkNode M2 ESP32-S3-based Meshtastic handset features 1.3-inch OLED display, 1,000 mAh battery

ThinkNode-M2 Meshtastic Messenger

Elecrow ThinkNode M2 is yet another Meshtastic handset for off-grid messaging and GPS coordinate sharing based on an ESP32-S3 module providing Bluetooth connectivity to a smartphone, and a Semtech SX1262 LoRa transceiver for low-power long-range wireless connectivity. It’s an evolution of the ThinkNode-M1, itself similar to the LILYGO T-Echo, based on a Nordic Semi nRF52840 Bluetooth module and SX1262 LoRa transceiver with an external antenna housed in a 3D printed enclosure. The new ThinkNode M2 is very similar but features a more powerful ESP32-S3 module instead, relies on a 1.3-inch OLED display instead of a 1.54-inch e-paper display, and is housed in an ABS plastic case. ThinkNode M2 specifications: Core module – ESP32-S3 module (looks to be ESP32-S3-WROOM-1 on the photo below) SoC – ESP32-S3 CPU – dual-core 32-bit microcontroller @ 240MHz Memory – 512KB SRAM, 8MB PSRAM Storage – 384KB ROM 4MB flash Wireless – 2.4GHz Wi-Fi and Bluetooth […]

A LoRa-based Walkie-Talkie? Meet LILYGO T3-S3 MVSR LoRa voice communication kit

LoRa Voice Communication Kit Walkie Talkie

With its low-power, long-range capabilities, LoRa has been used for P2P and Mesh messaging with firmware like MeshTastic, but due to its limited bandwidth, we haven’t seen quite as many LoRa audio applications. This has not stopped LILYGO from designing the T3-S3 MVSR LoRa voice communication kit, integrating LoRa radio, a microphone, and a speaker to use the board as a walkie-talkie solution working over Semtech SX1262 or SX1280 RF transceiver.
