ZY-JIN HB100 Microwave Sensor 10.525GHz Doppler Radar Motion Detector

[Jarrod Roberson]

Anyone have an information in english about how this part actually works?

Like its input/output protocols or anything else?

This looks like something might be appropriate for a project of mine, but I can't find any useful information via Google searches on the part number?

Hi,

I did a review of a HB200A radar module, which should be more or less the same:


It's powered from 5V DC and it's output is completely analog.
The output signal is something like this:
U_out(x) = 50mV*cos(2*pi *2*x/lambda)*(10cm/x)² + 15mV

The output amplitude is about 50mV on an offset of +15mV @ a distance of about 10cm.
From there on the amplitude drops with 1/x².

Greets,
Karl
