    2 out of 3 inexplicably stopped working. Maybe someone more knowledgeable than me can explain why these appear to be so sensitive that they fail after a few uses making them cheap but really, really c.r.a.p.p.y. I will stick to good old fashioned PIRs or try something different. Great paperweights. Actually, not good paperweights, too light, but work better than as a movement sensor. Well for a while it sent out a TTL 3 v when activated, then. Just. Stopped. Dammit.

    Tried with 5v and 12v output on the device appears be standard TTL logic 3.3v measured. 10mA not measured but looks good sensitivity unmeasured but worked as or better than hoped for expected and described. The wire and plug supplied is smaller than regular spacing. The HW-MS03 has the regular pin spacing otherwise basically the same.

    Tried 3 versions of sensor from BG These are + output with sufficient current to drive relay etc. With 2 in very close proximity they seem to interact @ the same f so will now try a different type and see if that stops hunting.
