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 […]

Radxa CM5 – A Rockchip RK3588S module (somewhat) compatible with Raspberry Pi CM4

Radxa CM5

Radxa has been working on the ROCK 5 Compute Module (aka Radxa CM5) system-on-module compatible with Raspberry Pi CM4, but based on the more powerful Rockchip RK3588S octa-core Cortex-A76/A55 SoC. Just like the Raspberry Pi Compute Module 4, it comes in a 55 x 40mm form factor, but instead of just two high-density 100-pin board-to-board connectors, the module includes three to cater for the additional I/Os from the Rockchip processor, just like they did for the Radxa CM3 equipped with a Rockchip RK3566 processor. Radxa CM5 specifications: SoC – Rockchip RK3588S octa-core processor with 4x Cortex‑A76  cores @ up to 2.4GHz, 4x Cortex‑A55 core @ 1.8GHz Arm Mali-G610 MP4 “Odin” GPU Video decoder – 8Kp60 H.265, VP9, AVS2, 8Kp30 H.264 AVC/MVC, 4Kp60 AV1, 1080p60 MPEG-2/-1, VC-1, VP8 Video encoder – 8Kp30 H.265/H.264 video encoder 6 TOPS NPU System Memory – 4GB, 8GB, or 16GB LPDDR4x‑4224 SDRAM Storage – Optional 8GB, […]

Sensirion SCD40 CO2 sensor units for makers: M5Stack UNIT CO2 and TeHyBug ESP8285 device

M5Stack UNIT CO2

We just wrote about the Infineon XENSIV PAS CO2 Shield2Go board to measure carbon dioxide (CO2) levels last week, but I’ve just come across two more hardware with a CO2 sensor designed for makers, but based on Sensirion SCD40 sensor instead, and mostly designed to monitor indoor CO2 levels since high concentrations may impact your health negatively. The first one is the M5Stack UNIT CO2 that’s designed to be connected to one of the company’s Core modules through an I2C interface, and TeHyBug portable mini sensor device equipped with ESP8285 WiFi microcontroller, as well as optional AHT10 temperature & humidity sensor and BMP280 pressure sensor, besides the SCD40 sensor. M5Stack UNIT CO2 Specifications: Sensirion SCD40 sensor CO2 Measurement range – 400 ~ 2000 ppm CO2 Sampling accuracy – ±(50 ppm + 5% of reading) Temperature range – -10 – 60°C with 0.8°C   accuracy Humidity range – 0 – 95% RH […]

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

Wi SUN network architecture

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

LilyGO LoRa V1.8 SX1280 antenna headers

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.
