HB-100 Sensor (Doppler Radar)

Okay Here is how I think I got it working...First off someone at Dangerous Prototypes did link a breakout board that does both logic out and analog (for RSSI): http://dangerousprototypes.com/2013/08/21/breakout-board-uses-hb100-doppler-motion-sensor/

I used the schematics on page 5:
http://www.limpkin.fr/public/HB100/HB100_Microwave_Sensor_Application_Note.pdf%20to%20build%20the%20Amplifier%20circuit.

Then used the frequency counter library:
http://interface.khm.de/index.php/lab/experiments/arduino-frequency-counter-library/
Note they use Pin 5 on Arduino because this connects to the counter.

Finally using page 7 of the manual shows the simplified formula to get Miles per hour for an object strait on:
http://www.limpkin.fr/public/HB100/HB100_Microwave_Sensor_Application_Note.pdf
Forumula: F_Dopper = 31.36(V)
F_Dopper, is the what the counter sees


The results are computed and displayed on an LCD screen using an I2C LCD library Adapter.

Now to see how well this works...Anyone else played with this sensor yet? I might use it for a motion sensor as it does see me walking towards it. In a small 12x12 room, I noticed the sensor will see my own moment from reflections as well.

I might order more soon. These work really well as motion detectors too!

electromagnetic frequency detector refers to another working wave field,that are common in our daily life as well ,so you can handle it easily.You can come to know more specification about it if you need one.

I worked for a company building/engineering cell detectors for a while...lol. Gave me the background i needed.

That's a great idea. I never thought os using them for a motion detector.

There is a newer sensor I'm getting a cheaper lidar like detector. Only good for sensing about 2 meter unlike LIDAR which is further.
