My other PIR multisensor, on coin cell

I love!
I was reading the other day about using White silkscreen layer on top, and then the names and values where on the top copper layer (being very careful), it gave the effect of pure white and gold plated. It looked beautiful!

@scalz - Could you take 2 minutes to check this MOSFET for me please, do you think this would work in our application? Once i get the board made i will be using the exact one you have, but i need to breadboard all of this together to learn.

@samuel235 I think you don't need a 17amp mosfet.. for breadboarding, you could use the common TO92 BS250 instead. just a thought :)

@scalz, i never chose that MOSFET due to its specs, its just the first i came across at the cheapest price available to me. However, i have found this one now and will only have to pay a small shipping fee. http://www.bitsbox.co.uk/index.php?main_page=product_info&products_id=1018

@NeverDie thx. I know this sensor. a bit thick. And I had others goals! thin and compact overall with custom box, I like custom box, you can think your assembly, and it's durable source (stl),
for sharing some parts, and fun a to z training/challenge :)@Samuel235 not yet. I have received pcb some days ago. but I'm missing few values to assemble pir. I delayed a bit my order because I have other board/bom, and try to have free shipping each time ;)
but I already use p mosfet on other sensors boards and that works nice...
true, I could have shown you what looks my pcb..so it's white because box will be white and with transparency, I don't want to see the board. But I noticed that each time silkscreen never looks good on white...few ugly things but that will be tiny and thin I think ! I can't wait to assemble it and debug it :)

You're doing a great job, but in my case, I'm currently motivated to move quickly and simply "get it done" and move on. Of course, if your project were already finished, I'd be very much interested in it for possible deployment. However, because it's not finished, I think I'd like to mysensor-enable an existing unit, especially if it works well, has long battery life, and is fairly inexpensive. Also, because motion detectors tend to be visible, having attractive industrial design on the enclosure is not unimportant, and that's hard to accomplish on a DIY basis without turning it into a "project."
So, in the meantime, have you run across any other off-the-shelf motion sensors with good battery life? Or, if not, have you found any with good enclosures? If worse came to worst, I could possibly just make use of a COTS enclosure after upgrading the electronics. For instance, I do have an outdoor Optex motion detector with low(ish) energy requirements and which can run on battery and which, by design, leaves space for inserting my own wireless transceiver.

@Neverdie
Thx. yep I understand. Each one his way, no way really better I think, your is nice too ;)
And like I said, I am much more interested in complete design. If I would like something complete, I would buy a commercial products for this kind of application or use the ikea molgan for ceiling. And you're right that PIR tends to be visible, but should not be too much visible too..that's why I prefer smaller/thinner box.
I'm now working on things which are more expensive to buy..because you can't save big money on this kind of device...That said I have no problem to design my custom box ;) The 3d box for this one is already designed, simple, for a compact 6m lense.
I enjoy to use Solidworks to design my custom 3d box (for me it's as addicitive as Eagle). I own a 3d printer and filament is cheap! And I would say I'm luckily well equipped to make all sort of diy :) An electronic lab with a reflow oven and nice tools! And a mecha part, with mini lathe, drill press, tig... and more!So you see not a problem on my side, just the time, but I have to relativise, my iot thing is not so hurry compared to my daily job. I should assemble one very soon now, things are coming. And this design is well know from TI, I have just adapted it a bit, just another alternative ;)

I see that Olimex has a version of TI's reference design. Currently $16 on Amazon, with Prme delivery. Coincell powered, small, but no enclosure.

I have looked on AZ, but can't find this version of TI's ref design. Can you provide a link?

That's funny. I thought I had posted the link. Might it have been auto-deleted from my post if it's no longer carried on Amazon?
Anyhow, at present I'm pursuing the AM612 instead.

@NeverDie I have seen reference to the Olimex version of the TI ref design in the past on other forums, but I have never seen a link to it. I have scoured the web for something that will point me to it. Can you point me in the right direction? Thanks.

@scalz How did your testing / calibration go for the PIR ?
I would love to pay a fab house to put one of these amazing boards together as I'm sure would many other folk watching your work! :) -
@tomtastic
yes I played with different PIR sensor design :)- The other (old) thread you're linking (with booster and special PIR ic) is working well too, but if i remember I never realeased it completely because I wanted something smaller and lower power..
- And regarding this thread, it is now located https://www.openhardware.io/view/75/MyMultisensors and it works well too. It is smaller and thinner than the old board.
I have also another nice design for nrf52 (again, smaller) but actually busy with my job.
