    I did a lot of practical testing on this little sensor and found that it seems to work at great range 360 degrees although what is to be considered as the actual front of the sensor is more sensitive I was able to get good detection from even at the sides of the board at the full length of my living room, I'd say that is around 25 to 30 feet. approaching from the top of the board gave no detection at all but it did seem to work very well 360 around the antenna. I placed a plastic project box along with a glass cover and still got good results at 360 degrees around the antenna

    No transistor needed. You can wire the LED directly to the output pin. There's a 100ohm series resistor on board.
    Data and schematics for the chip (RCWL-9196) and the board (RCWL-0156) can be found here:

    These documents also show some options that are available on the board for adjusting range, trigger cycle time and light sensitivity (if using with a photoresistor).

    So do you know what the exact SMD Capacitor is for the required sensor to extend the trigger time?

    A comparison between those radar modules and the common PIR motion detector modules would be interesting. Ie comparing range, detection cone and sensitivity.

    Will it only work for humans or will a stuffed animal or other moving object set it off? Like tree branches moving in the wind?

      I think it would probably work for all sorts of things ... but ... If you imagine the detection cone spreading out from it, I suspect at any distance it would need a large object.
      So small pets might not trigger it unless they were very near

      I'm pretty sure it does not need to be alive. It needs to be moving.

    Assuming this outputs an analog range why not start characterizing it with a microcontroller script? This simply demonstrates that it powers on but you've really learned very little about the range, sensitivity, and coverage of the device.

      I'm pretty sure it's only outputting a trigger / no trigger. But as soon as it's properly housed I will test it more thoroughly

      Normally this sensor is used in conjunction with a infra red to reduce the false positives in an alarm system. I suspect this board exists because the chipset used in the security market became very cheap. We will see after some digging what it can do, a datasheet may even exist

      Not an analog output -- only on/off.
