DeNova Detect natural gas alarm works with Amazon Sidewalk network

Denova Detect Amazon Sidewalk natural gas alarm

New Cosmos’ DeNova Detect is a wireless natural gas alarm that works with the Amazon Sidewalk network designed for low-power, low-bandwidth IoT devices in and around the house, benefiting from free connectivity thanks to the installation base of Amazon devices such as the Echo Show acting as gateways. DeNova Detect does not require wiring to mains, and the device is expected to achieve an extended battery life of seven years, so customers can choose the optimal location for a gas alarm in their homes without needing to be close to an electrical outlet. There’s no need to have an additional gateway such as with LoRaWAN solutions as well as the customer owns one or more Sidewalk-compatible device. Note that Amazon Sidewalk is currently deployed in the US only with global expansion planned for later. Amazon Sidewalk relies on Bluetooth LE inside the home, Sub-GHz GFSK on the sidewalk/around […]

Wi-SUN: An LPWAN standard for Smart Cities, Smart Agriculture, large scale IoT deployments

Wi-SUN is a standard (IEEE 802.15.4g) managed by the Wi-SUN Alliance and designed for Smart Cities, Smart Agriculture, and other large scale IoT deployments with a large number of devices thanks to the use of IPv6 mesh networking. The organization was founded in 2011 to “support the worldwide development of Wireless Communications Networks for Utilities, Smart Cities and IoT”, but due to the niche nature of target applications, it does not get that much press coverage and was only recently brought to my attention. Wi-SUN stands for “Wireless Smart Utility Networks”or “Wireless Smart Ubiquitous Networks”, and the standard aims to connect streetlights, cameras, weather stations, smart metering, utility transmission systems, and others to enable data-sharing between city services to improve their efficiency, save costs, and offer improves services to citizens. Wi-SUN FAN (Field Area Network) is the latest protocol managed by the Wi-SUN Alliance with over 95 million units shipped […]

ESP32 board supports 2.4Ghz LoRa with SX1280 RF transceiver

We’ve seen plenty of ESP32 LoRa boards with the traditional 433 MHz, 868 MHz, or 915MHz frequencies, but I think LilyGO LoRa V1.8 (aka T3 V1.8) is the first ESP32 board that integrates a Semtech SX1280 transceiver for the 2.4GHz LoRa standard used for global coverage, notably maritime applications, and ranging. The ESP32 & SX1280 board also offers 26 pins for expansion, a microSD card for data storage, a 2-pin connector for batteries, a 0.96-inch OLED for information display, and comes with a 3D antenna and u.FL connector for WiFi and Bluetooth, and an SMA antenna for LoRa connectivity.

Sparrow is a sensor-to-cloud LoRaWAN solution based on STM32WLE5 microcontroller

Blues Wireless Sparrow is a LoRaWAN solution designed to connect a group of low-cost, low-power device sensors for shared data backhaul to the cloud. It is comprised of STMicro STM32WLE5 LoRa-based sensors whose data is then routed through the company’s Notecard-powered WiFi or cellular gateway and ultimately a cloud app hosted on AWS, Microsoft Azure, or other IoT cloud platforms. The company claims the Notecard and Sparrow solutions ease the development of IoT networks in a way that was previously only available “to sophisticated engineering firms”, and now Blues Wireless supports cellular, WiFi, and LPWAN technologies. Let’s have a look at the “Sparrow Essentials” board specifications first: Wireless SoC – STMicro STM32WLE5+ Arm Cortex-M4F microcontroller @ 48MHz with 256KB Flash, 64KB of SRAM, Semtech SX126x LoRa transceiver I/Os Breadboard compatible 2.54mm headers with digital and analog I/O, I2C, UART, and SPI Qwiic Connector Debugging – JTAG (SWD capable) debug jack […]
