Mysensors S_MOTION shows up as S_LEAK

Hi,

Just tried to connect a motion detector using the mysensor library and the example sketch for motion detection on mysensors.org. The child is declared as S_MOTION but shows up as S_LEAK in Easyiot once the node has been added.

But the communication seems to work as I get "OK" or "Leak" on the node on the frontpage when waving my hand in front of the motion detector

Ahh, good to know Thanks for the quick answer!

I havent got around to it yet but the plan is to make it batterypowered. The sleep function implemented in mysensors library allows for waking on interrupts only which has been my plan to use. No tested it yet though.

So as long as i manage to tune the sensitivity and trigger time not reacting at too small movements/too quickly I figure it should be possible toput it to sleep quite a lot of the time and manage on batteries. The main concern is the current draw of the motion sensor in standby.

Ok, so just made some quick measurements of the current draw of one of these PIR motion sensors. Its actually not bad. In standby it hovers somewhere around 50-60 microamps depending on incoming light it seems. When it detects changes the consumption rises to 200-300 microamps. So even without removing the power regulator, i think its pretty ok.

I also tried running it directly from 3.3v but even if it seemed to kind of work it was much less sensitive and i got the feeling that the trigger time changed. If removing the voltage regulator I guess it needs to be powered from 3.3v?

Nice sketch for the door/window sensing! But I dont think you need to call powerUp and powerDown manually. All that is taken care of in the mysensors sleep command. According to mysensors.org that should put both radio and arduino in powerdown mode which i think is correct . At least it mathes the current measurements I have done.
