    For PIR, there is a low power design proposal by ST here. Perhaps something to consider? I would like to make one myself, but I do not have the time for that right now. Could be useful for battery-driven PIR.

    Do you feel secure today? No? Start requiring some signatures and feel better tomorrow ;)

      @Anticimex : it seems very interesting. Something I was searching for.. I have found some others links different, but not easier to implement as your link. A low power PIR could be great, this is something missing in our battery powered sensors toolbox. I will look at this asap. Thx for share :smiley:

        @scalz No problem :) I would replace the 4-resistor voltage dividers with potentiometers instead. Fewer components and much more tunable :)

          @Anticimex: yes, good idea. I am still waiting my D203s pir sensors. asa I get them, I try your link on breadboard and give you some news. thx. see you soon :smiley:

              Can i buy his board?

              Domoticz, with a lot of working hardware, include mysensors :-)
              OpenPLI, RuneAudio, Solarmeter, etc......

              Not a great builder of software and hardware, more a user...
              Only i try to do my best :-(

                @Dylano: thx for interest :). I am comparing few pcbas, waiting my reflow oven much for small batch and boost prototyping than selling. I would prefer to have a good quotation or deal like limited partnership maybe...

                In fact I have other boards in progress maybe you would prefer..
                This one is based on mytinycamel, a board I made for ultra low power <1uA + booster, and for the exercise of power sequence&mosfets.... but it is better for telemetry application than PIR motion sensor.
                Plus, here it needs a shield which add a little bit thickness, for indoor, I know it's just few mm...

                So I made this one, better for pir (in progress, I will post pics) : http://forum.mysensors.org/topic/2951/my-mysx-multisensors-board

                but mytinycamel is still actual because modular and enough cheap too, it works but I redraw it to add more connectors as i don't need pir on this one. rfm69 or nrf, ldo or booster+ ultra low power modee, eprom, power on/off sensors radios 2.4x5cm blabla...looks like this now with 3 connectors for common sensors.

                Note: I have not yet this rev, this is a part of my week order ;) (with a dhl in my face please, as I am not so patient ...)

                So for the moment nothing to sell, but in future..I would be glad :)

                  I wait..
                  Hope you give a signal here when there are new possibilities..
                  And i hope you will share a stable sketch... for battery devices.

                  good luck!!

                      @alexsh1
                      veml6070 works nice.
                      that's a while i've done this ulpnode board. finally i've done my coincell multisensors for indoor.
                      And now, for lot of sensors etc i use more powerful mcu.
                      That said i have a weather extension board with lot of sensors including the veml6070. will try to release when i'have time ;)
