The HB100 doppler modules you can find on tindie or ebay need some electronics to operate them. This fundraiser is for a HB100 module with its backpack, which contains all the necessary components. Please note that the assembly you'll receive may have a 90 degrees back connector as a straight one may damage the envelop it is shipped in. To make it work, you just need to apply 5V and you're good to go!
Input & Output signals
- 5V / 50mA input
- Frequency output, proportional to the object's speed
- Voltage output, proportional to the amount of reflected RF signal
Please have a look at the above video, which shows what you should expect. For advanced technical specifications, please have a look at my webpage.
As I don't have much time these days, the assembly will be made by smart-prototyping in Hong Kong. They are the ones who produce and distribute my whistled project, so you don't have anything to be worried about :).
For information, smart-prototyping distribution fee + production & assembly cost should be around $17. Tindie + credit card processing fee is around $2 and envelope cost + shipping fee will depend on the final quantity.

How hard would it be to hook up the vcc out put to a relay

You would need to make another circuitry with a programmable threshold to activate the relay, as the module can't provide enough power.

Will this work if I need it for a project that measure the speed of an approaching object? I need to connect the module to an Arduino and calculate the speed.

Yes it will, as it is actually what it is made for :)

Looks like a fun sensor! I would like to know what kind of beam u use? Is it narrow ore very broad, maybe you have the antenna pattern?

It is a fun sensor :). It is 10.5GHz, and you can have a look at the radiation pattern here: http://www.limpkin.fr/public/HB100/HB100_Microwave_Sensor_Module_Datasheet.pdf
I received this in good condition. I haven't used this in an application but I did set it up on the bench for testing. The HB100 seems to have a fairly substantial integrator... or I'm assuming that's what it is. Maybe it's just a function of the device? I've never really worked with a detector like this before so maybe that's just how they respond? Interesting device and I can see a use for this in a project in the near future. Excellent product, I highly recommend this.
