In deep Sleep the cunsumption is below 19µA, but i have to send with PA_MAX. On some Windows the open/close frequency is verry high, so the battery is to fast emty. The CR2032 is good, but i want more "lifetime"

Hi @tbowmo, do you mind to explain a bit about the design? I'm interested with your design. I will use these steps for removing voltage regulator, http://goo.gl/CsZaNg So the design will be battery > external step up regulator (http://goo.gl/PFt99R - to stabilize 3.3v) > vcc pin ? with these then I can use my first post design? Thanks

Thanks again, learned a lot... I decide to give a try there, I also had a look on some components' datasheet and seems to be what I need... Let's see, if end up getting the boards I'll publish a review here later.

@hek : Thanks so much... no idea why I didn't see that earlier. I think you can close this post.

@nekitoss I used 3.3V pro mini with regulator removed and powered by Vin pin. Also removed leds from the pro mini. I used minicore bootloader. I used the small pir sensors and again removed the regulator to power directly from the pro mini outputs. After that sleep the node and trigger on interrupt. Send battery level once a day. Use inbuilt battery level monitor and not external components that constantly drain power to get battery level. 1.8V is 0% on the graph (not visible yet!) but I have had nodes working below 1.7V It's a matter of luck with that it seems. Hope this helps you on the right track. I'll try and help if you want. This is the latest image and still going strong after 18 months. Voltage is at 2.903V Here is photo of the test example - I need to make a case and produce more of them over winter..... Here is the same build/code of a window sensor. Similar time frame but hardly triggered.....

Thank Sensor ready work. (I have not valid binary Optiboot)
