More than I expected. I thought it was about the same size as my SmartThings motion sensors, but it's a lot bigger. Seems to work pretty well with my Pi3. For some reason it's less reliable when I connect it to Pi Zero. Not sure why. I usually use my Pi3 for setup as it's much faster and the remote desktop is faster, and when I'm done I pop the microSD into the Pizero and transfer the hardware. Works great with everything except this motion sensor. Often dims when nothing happens even though the lowest possible sensitivity is set. If I set the sensitivity to high, he sees movement all the time. 3 stars as it seems to work well depending on what device it is connected to. I had the same experience with two of them and also with two different Pis. I ended up not using them as they weren't very reliable with zero pi.
