Seeed Studio launches ESP32-C6-powered 60GHz mmWave human fall detection and breathing/heartbeat detection sensor kits

mmWave human fall detection and heartbeat sensor

Last year, we reviewed the MR60FDA1 60GHz mmWave fall detection sensor kit, which utilizes the XIAO ESP32C3 module as its core. This module, featuring both Wi-Fi and Bluetooth connectivity, opens up various IoT applications. Now, Seeed Studio has introduced advanced mmWave sensor modules specifically designed for enhanced fall detection and heartbeat monitoring. The MR60FDA2 is optimized for fall detection, while the MR60BHA2 is designed for heartbeat monitoring. Powered by an ESP32-C6 WiFi 6 and RIS-Bluetotoh LE microcontroller, these modules offer reliable detection for real-time fall monitoring and accurate heartbeat tracking. They also feature customizable RGB LEDs and ambient light sensors, providing additional flexibility. With expansion options via Grove GPIO ports, these versatile modules are well-suited for applications like smart home integration and healthcare monitoring. Previously, we covered the RoomSense IQ and the DesignCore RS-6843AOPU with mmWave technology. The RoomSense IQ is an ESP32-S3-based modular room monitor with mmWave radar presence […]

SONOFF ZBMINIR2 tiny Zigbee 3.0 switch also works as a Zigbee router with up to 64 sub-devices

SONOFF ZBMINIR2 is a tiny Zigbee smart switch that looks very similar to the SONOFF Zigbee Extreme (ZBMINIL2) but requires a neutral wire and can act as a Zigbee router with up to 64 sub-devices. It also supports new features such as “Turbo mode” for extended range and “detach relay” mode where the states of external switches and relay are separated, so operating the external switch button won’t affect the relay state. The tiny wireless switch can fit into the smallest EU-type/86-type/120-type mounting boxes and works with gateways supporting the Zigbee 3.0 protocol such as ZBBridge Pro, NSPanel Pro, and other compatible Zigbee 3.0 hubs. It also supports external switches (momentary, door, SPDT, and rocker), voice control through Amazon Alexa and Google Home, and like other SONOFF devices is designed to be controlled through the eWelink mobile app by default. SONOFF ZBMINIR2 specifications: MCU – Unspecified – Potentially the same […]

Integrated motor driver and controller bundles ESP32-S3 and TMC2209 for IoT applications

The PD Stepper is a NEMA 17 integrated stepper motor driver and controller board powered by USB power delivery that combines an ESP32-S3 wireless microcontroller, the Trinamic TMC2209 ultra-silent motor driver, and other components onto a single board for Smart Home and automation applications. The maker, Josh R., states that the PD Stepper isn’t another “just because we can” project. It addresses the need for an integrated motor driver and controller module that can used in compact or space-constrained designs. The ESP32-S3 SoC controls the other components on the board and provides wireless connectivity as well as access to development tools and libraries such as ESPHome and ESP-Now. The motor driver IC, Analog Devices’s Trinamic TMC2209, offers efficient, noiseless control of two-phase stepper motors. Other onboard components and connectors include an AS5600 magnetic rotary position sensor, a 3.3V buck converter, a Qwiic/Stemma QT connector, a motor connector, and an AUX […]

WiCAN Pro – An ESP32-S3-powered OBD scanner for vehicle diagnostics with Smart Home integration (Crowdfunding)

MeatPi Electronics introduced the WiCAN Pro, an ESP32-S3-based OBD scanner, and the successor to WiCAN-OBD. Equipped with an OBD-II interface IC, it provides full support for all legislated OBD-II protocols. It offers compatibility with multiple CAN Bus protocols, including three standard CAN Bus and single-wire CAN Bus. The previous generation WiCAN module came in an OBD or USB-based version. The WiCAN Pro only has an OBD interface, but another significant difference from the previous product is that it features a USB host port. This port can power USB devices up to 1.5 amps at 5 volts and enables capabilities like adding GPS or cellular-based radios, like with meatPi’s ESPNetLink add-on. WiCAN Pro specifications: Wireless Module – ESP32-S3-WROOM-1-N16R8 SoC – Espressif Systems ESP32-S3R8 dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration, 512KB RAM, 8MB PSRAM Storage – 16 MB flash Wireless – 2.4 GHz WiFi […]

Mixtile Edge 2 Kit review with Home Assistant, 2-in-1 Zigbee & Z-Wave mPCIe module

We received the Edge 2 Kit IoT gateway on the Rockchip RK3568-powered Edge2 single board computer (SBC) and a 2-in-1 Zigbee and Z-Wave mPCIe card from Mixtile which we will be reviewing from the perspective of smart home applications using Home Assistant open-source home automation framework. Let’s dive into the details. Unboxing Mixtile Edge 2 Kit CNX Software previously reported on the Mixtile Edge 2 Kit in 2022 and you can check the detailed specifications and block diagram in that earlier article. Since then, Mixtile has found a wider range of applications for the device and is also promoting it as an Edge AI Box that performs AI object detection using the Edge 2 Kit (or the more powerful Mixtile Blade 3) using the built-in NPU (Neural Processing Unit) with up to 1 TOPS of AI performance for tasks such as object detection. Let’s unbox it and take a closer […]

The Open Home Foundation adds HACS, microWakeWord, and Music Assistant open-source projects

Open Home Foundation adds HACS, microWakeWord, Music Assistant

HACS, microWakeWord, and Music Assistant projects have joined the Open Home Foundation launched a few months ago to manage open-source projects related to Home Assistant and Smart Home applications in general separating them from Nabu Casa’s commercial activities. Note the HACS, microWakeWord, and Music Assistant projects will not operate directly under the Open Home Foundation’s umbrella, but they are external projects that the foundation collaborates on since it believes those are projects worth investing in to further develop the Smart Home ecosystem. Let’s have a quick look at the three projects. Home Assistant Community Store (HACS) is the most used custom integration for Home Assistant and allows users to easily install custom integrations, cards, and themes. Music Assistant gives users control over their media players and audio files handling both local music collection and music streaming services so that users can play any tune anywhere in their house without restrictions.

SONOFF SWV Review – A Zigbee Smart Water Valve tested with eWelink and Home Assistant

Today, we are going to test and review another new Zigbee product from SONOFF, the SONOFF Zigbee Smart Water Valve (SWV). This is the first water valve built by SONOFF. When it comes to devices related to water control, whether watering plants or opening and closing valves in tanks or pools, many people might be familiar with the SONOFF 4CHPro model, which is a WiFi smart switch that controls solenoid valves with DC or AC power (valve sold separately). The SONOFF SWV is an all-in-one device that integrates both valve control and IoT functionality in one. It is ideal for plant watering around the house or controlling water filling into pools or tanks. Besides being able to set schedules for opening and closing valves, it also has other interesting features. Let’s look at the details. Unboxing the SONOFF Zigbee Smart Water Valve Inside the box, you will find the valve […]
