SocioNext MN87900 is a Really Tiny 24 GHz Radio Wave Radar Module for the Internet of Things

In the past, we covered tiny microwave radar modules operating at 5.8 GHz and measuring just 32 x 23 mm. Those modules are normally used to detect motion, distance, and/or direction of movement. Socionext has now introduced MN87900, a single low-power single-chip 24 GHz radio wave IoT sensor solution that even smaller at just 12x7mm with the chip, Tx and Rx antennas, crystal, and 40-pin to solder the module to your board. The solution targets IoT equipments, security systems, smart home appliances, autonomous vehicles and drones, medical devices, and more. SocioNext MN87900 key specifications: Sensor Type – CW, FSKCW, FMCW (moving or stationary) Detection Motion direction – approaching or leaving Motion speed – up to 200 km/h Range – 0.15 to 8 meters 80°@-3dB, expandable to 30 meters  with a radome horn, a metal shield that narrows the field of view. Variable frequency width –  24.15±0.1 GHz Transmission Power – […]

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 […]

Walabot MIMO Radar Board Can See Through Walls Thanks to Vayyar 3D Imaging Sensors

A few days ago, I wrote about Orbbec Astra 3D camera that can analyze distance and depth to form a 3D image of object. However, this solution uses an IR sensors, and while it can fulfill the needs of many application it does not allow to see through object, and that’s exactly what Walabot wideband MIMO radar board promises to do thanks to Vayyar 3D imaging sensor and a dozen of RF antennas. Some of the key features and preliminary specifications of Walabot board include: Vayyar VYYR2401 3D imaging sensor 12 (or is it 14?) non-contact antennas array system based on “Octopus A3 System on chip” Build in Tx/Rx linear polarized wide-band antennas from 3-10Ghz. On-board Cypress FX3 controller for communication and pre-processing EEPROM (for inventory and calibration information) Walabot interface connectors: Micro-USB 2.0 for high-rate data communication. Option to provide supply from USB. Single supply voltage 4.5-5.5v input for […]
