Making the Electronics for a 24GHz doppler motion sensor

Tuesday, April 4th, 2017

Limpkin has a nice write-up on his tiny CDM324 Doppler speed sensor: You may recall the article I wrote a couple of years ago about a nearly identical Doppler sensor, the HB100. While the HB100 is using a 10.525GHz frequency, this new module uses 24.125GHz! This has the main advantage...

Breakout board uses HB100 doppler motion sensor

Wednesday, August 21st, 2013

limpkin has been working on a dev board for the HB100 microwave sensor. He developed a breakout board that allows the module to operate as a motion sensor. "I'm sure you're quite familiar with the Doppler effect: you send an RF signal at a given frequency to a target, and...
