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 […]

DALI2 expansion module for ESP32-C6-Pico and ESP32-S3-Pico boards facilitates Smart Lighting integration

Waveshare has recently launched the Pico-DALI2 expansion module for ESP32-Pico series boards designed to enable DALI communication for customized control of multiple lighting groups. It is compatible with development boards such as the ESP32-C6-Pico and ESP32-S3-Pico and includes a DALI communication screw terminal for connecting external DALI devices. DALI (Digital Addressable Lighting Interface) is a standardized protocol used for lighting control in building automation systems. The latest version of the DALI2 protocol is better than the old one in that it offers enhanced interoperability, additional features like multi-master configurations, and better energy management capabilities. DALI2 devices can communicate bidirectionally, meaning controllers can send commands and also receive status feedback from lighting devices, allowing for more complex automation and diagnostics. We can get more information about DALI from Wikipedia. We have previously seen the uses of DALI in Texas Instruments MSPM0 Arm Cortex-M0+ microcontrollers as an interface and in Acme CM3-Home […]

Spectra is a customizable, JavaScript ESP32-S3 and nRF52832 smartwatch (Crowdfunding)

Spectra is a JavaScript-based hackable smartwatch based on the ESP32-S3 WiFi and Bluetooth microcontroller that aims to offer the quality of high-end consumer smartwatches with the repairability of a maker-targeted device. The Spectra smartwatch combines the ESP32-S3 microcontroller with a Nordic Semi nRF52832 co-processor to optimize the battery life. The ESP32-S3 is maxed out with 8MB of RAM and 32MB of external flash memory, and the microSD card slot in the watch supports up to a 512GB memory card. It shares a similar concept with the Bangle.js and the Bangle.js 2 customizable smartwatches. According to the maker, Spectra is not bound to be fully open-source, since the project uses “external proprietary code [they] aren’t allowed to share.” They plan to publish Arduino libraries and hardware design files, but there is no live GitHub repository yet. Other hackable smartwatches include the TinyWatch S3, the ZSWatch, and the Sensor Watch Pro. Spectra […]
