https://www.electronics-lab.com/xensiv-bgt60ltr11aip-radar-shield2go/
Infineon’s super-low-power 60 GHz Doppler radar sensor includes antennas-in-package (AIP) Infineon’s Radar Shield2Go can be used independently as a plug-in radar sensor (e.g., with Arduino form factor boards or another microcontroller) to detect motion and direction of motion by using only two GPIOs (TD and PD) in autonomous mode (default). The board comes with two […]
Microwave Presence detector works using Doppler Effect
https://www.electronics-lab.com/microwave-presence-detector-works-using-doppler-effect/
It detects stationary and moving people just like a PIR, but it can do that also behind doors and thin walls, by taking advantage of the Doppler effect. By Boris Landoni @ open-electronics.org: The detection of people, animals and hot bodies in general has been done for years using passive infrared radars, also known as […]
Tutorial, Experiment & Teardown of a 24GHz Doppler Radar Module
https://www.electronics-lab.com/tutorial-experiment-teardown-of-a-24ghz-doppler-radar-module/
In this episode Shahriar demonstrates a full analysis of a CDM324 24GHz Doppler radar module from IC Station. Opening the module reveals a series of microwave PCB components and several active devices. A complete analysis of the module is presented. The unit is then measured and the impact of antenna impedance and power supply voltage […]
Teardown and experiments with a Doppler microwave transceiver
https://www.electronics-lab.com/teardown-experiments-doppler-microwave-transceiver/
Kerry Wong did a teardown of Microsemi’s C900502 X-band planar transceiver: I got a couple of Microsemi’s C900502 10.525 GHz X-band Doppler radar motion sensors a while ago. This batch was made in UK and had “UK patents 2243495 and/or 2253108 apply” printed on the case. I have seen a teardown of an HB100 Doppler […]
