Hi @carlierd
i'll fix this! There is still my first version i posted there, on the old topic, https://forum.mysensors.org/topic/3600/my-other-pir-multisensor-on-coin-cell
PIR is repsonding well, depending of the sensitivity i set in sketch. same for batt!
Many sensors but all low power :) Except reed switch option, of course my power consumption results above are without reed switch. If i need it, i use a 1M res min (increase a few uA).see you soon
-
@anticimex almost! in fact i noticed that's mostly the same schematic if you look at different source. of course it's a PIR ! Regarding the app note you showed me, resistors, capa values changed, and not same ref of comparator (lower power consumption here). so it's very low power :)

Would it be possible to buy it pre-assembled soon?

Hi.
yes i'm preparing files for the fabhouse.
As you can see i've done a little update on my description, i'm focusing on my "work in progress" stuff to "released" at openhardware because i would like to release my others boards etc. and have my mind free for software. That will be hard for a pcb addict like me :)
I hope we'll get a reasonable price..This will be a project for contributing to Mysensors project ;) -

Hi,
is it possible to get the actual sketch ? -
hi.
i've updated the bom. you can use CSTCE8M00G55-R0.
it's optional, you can omit it if you want, and use internal 8mhz -
Hi, which tool do you use for programming with your pogo pin avr isp ?
Why didn't use pogo pin for FTDI too ?
-
@scalz Thx but how do you connect your USBASP on the pogo pins ?
I use an usbasp like this http://d1gsvnjtkwr6dd.cloudfront.net/large/AC-PG-USBASP_LRG.jpg but i don't see how to connect him on the pogo pins ;) -
nothing fancy..with dupont cable.
of course you won't connect the pogo directly on the usbasp.
make a small adapter. simple and cheap :)
Example with ftdi adapter

@scalz Awesome board, really. However, I'm a bit worried about its practical use. You see, the motion sensors are commonly placed near the ceiling or sometimes on the ceiling. This may induce a serious drift in the reported temperature. Ideally, a temperature sensor should be placed in the middle of the wall.
Some people would have the impression that they're wasting energy on heating during winter while others would boost their A/C units during the summer just to read they temperature they feel confortable with. This effect would be mitigate by either concealing the motion sensor at a proper height for temperature reading, or use a reference sensor for calibration and compensate the reported value of an improperly placed sensor, and that's assuming that the seasonal variation is linear.
Anyway, excellent SMD work, I'm still in the PTH ice age :grinning: -
@mihai-aldea
thx :)
of course i won't use temperature/hum sensor on the ceiling. Boards are small i can put them everywhere i want.
On my side, i just need one temp/hum/lum per room, and at least one PIR. This board needs to be well placed of course.
But if i need more PIR only, or temp/hum only... it's also possible. So i don't need to have a dedicated pcb per use. I stencil only what i need ;) -
I guess ordering the pcb will only get me the pcb. I need to do the soldering etc myself ?
But I really wonder how to solder such a board seemingly being smd soldering. Are there any guides available for someone like me (pretty handy, but not experienced in this hardware stuff) ?
Thanks ! -

Speaking of which, I thought there were going to be some mysensors manufacturering partners who would actually make this stuff, including the soldering. When is that going to happen?
