STMicro ST60A3H0 and ST60A3H1 60 GHz transceiver ICs aim to replace USB cables

ST60A3H0 ST60A3H1 60 GHz transceivers

STMicro ST60A3H0 and ST60A3H1 are short-range 60 GHz transceiver ICs that tunnel eUSB2, I2C, SPI, UART, and GPIO signals and aim to replace USB and other cables in consumer devices such as digital cameras, wearables, portable hard drives, and small gaming terminals. They should also find their way into industrial applications such as rotating machinery where cable use may be challenging. The smaller ST60A3H0 chip provides more flexibility and requires an external antenna, while the ST60A3H1 chip is a fully integrated solution with a built-in linear antenna. Both are capable of USB 2.0 speeds of up to 480 Mbps and support UART, GPIO, and/or I2C signals so they are not limited to USB cables and can be used in a range of applications. ST60A3H0 and ST60A3H1 key features and specifications: 60 GHz V-Band transceiver for short-range contactless connectivity up to 480 Mbit/s eUSB2, UART, GPIO, or I2C RF tunneling Low […]

Seeed Studio mmWave sensor kit – Part 1: unboxing and first impression with ESPHome and Home Assistant

mmWave Human Detection Sensor Kit Review Home Assistant

Excited to share my first review, written for CNX Software! This time, we’re diving into the Seeed Studio mmWave Human Detection Sensor Kit, which harnesses the power of mmWave radar. The technology I’m particularly interested in for its smart home potential. Therefore, I jumped at the chance when CNX Software offered a product review opportunity. The kit arrived promptly at my doorstep just one week after accepting CNX Software’s offer. Here are my initial findings of the product and its capabilities to replace existing motion detection products.  Unboxing the mmWave sensor kit I opened the DHL box and found the neatly bubble-wrapped mmWave Human Detection Sensor Kit. Alongside the kit, I discovered a bonus: the MR60FDA1 60GHz mmWave Sensor – Fall Detection Module Pro. This higher-frequency module boasts better resolution and even adds a fall detection feature compared to the kit’s included module, the MR24HPC1. However, the MR24HPC1 24GHz mmWave Sensor […]

RoomSense IQ – An ESP32-S3 modular room monitor with mmWave radar presence detection (Crowdfunding)

roomsense iq mount rotation v2

RoomSense IQ is a modular room monitor for presence-based home automation based on the ESP32-S3 module with Bluetooth Wi-Fi connectivity. It uses physical presence detection to automate your smart home devices. It comes with multiple sensors that can be used to detect human activity and track ambient light, temperature, and humidity levels. It uses mmWave radar technology to determine when rooms are empty and when they are occupied. It also features built-in temperature, humidity, and light sensors for indoor climate monitoring and control. Rather than relying on schedules, or voice detection, RoomSense IQ triggers automations or alerts based on whether people are in a room or not. It is therefore possible to set it to automatically turn off lights or air conditioning in rooms that are empty to save on energy. In addition, the device offers distance to target measurement that can be adjusted to trigger certain actions. RoomSense IQ […]

SONOFF SNZB-06P Zigbee human presence sensor is based on a 5.8GHz microwave radar

SONOFF SNZB-06B human presence detection sensor

ITEAD has launched a new Zigbee sensor with the SONOFF SNZB-06P designed to detect human presence using a 5.8GHz microwave radar whose main advantage over a traditional PIR motion sensor is the ability to detect stationary persons since this type of sensor can detect breathing. You’ll need a Zigbee Hub from SONOFF such as the NSPanel Pro or SONOFF iHost, or from other manufacturers, for instance, the Amazon Echo Plus 2nd generation, or simply use a Zigbee USB dongle such as the SONOFF ZBDongle-E connected to a host like a Raspberry Pi. Configuration and control is done through the usual eWelink app for Android or iOS. SONOFF SNZB-06P specifications: MCU – Silicon Labs EFR32MG22 wireless microcontroller Human presence sensor 5.8GHz microwave radar Sensitivity configurable from 2.5 meters to 4 meters Wireless – Zigbee 3.0 (router type) up to 30 meters Misc – Red LED, magnetic base, button Power Supply – […]

Socionext 24 GHz Radar Sensor for IoT Measures Distance and Angle (Video)

24 GHz Radar Location Distance Demo

Last year, we wrote about Socionext MN87900 24 GHz radio wave radar module for IoT with Rx & Tx antennas and a crytal unit that measured just 12×7 mm. The module is made for IoT equipments, security systems, smart home appliances, autonomous vehicles and drones, medical devices, and more. Basically any application that requires distance measurement up to 8 meters (expandable to 30 meters with a radome horn), rough location, or motion detection may leverage the technology. The company has now uploaded a video showing a demo of their 24 GHz radar sensor. Socionext did not explain which exact solution they used, and it’s probably not the full module above, but either one of their sensors based on the link provided in the video description: SC1232AR3 – All-in-one RADAR sensor for Entry Motion & Distance Detection SC1233AR3 – All-in-one RADAR sensor for Entry Motion & 2D Detection I suspect SC1232AR3 […]

Infineon Showcases the Radar Board used in Google’s Project Soli, and Sense2Go Development Kit (Video)

Google’s Project Soli sensing technology uses a miniature radar to detect touchless gesture interactions, so that you can control devices such as wearables using gestures without having to physical touch the product. The 60 GHz radar technology used in the project has been developed by Infineon, and the company was recently interviewed by Arrow Electronics where they showcased Soli board, as well as another 24 GHz radar development kit called Sense2Go. The Soli board called BGT60TR24 features Infineon XMC4500 ARM Cortex M4 MCU, and a 60 GHz “CRIS20” radar chip designed specially for Project Soli by Infineon, and allowing 20mm resolution, falling to less than one millimeter with Google’s algorithms. The micro USB port will be used for power and programming. This board should be the one included in Project Soli development kit to be shipped to developers this fall. Infineon also have a Sense2Go 24GHz sensor development kit that […]
