Donate to support Open Hardware@berkseo Good question. The code seemed good at the time I wrote it, but I can't say that it was extensively tested. I may circle back to it at a future date, and if so, I'll take a closer look. Even with more than 500 downloads of the code, no one has posted any feedback on how well (or not) it has run. Also, I not sure how compatible the posted code is with newer releases of the mysensors library.
This PIR sensor is powered by three AA batteries, which should easily power this sensor node for more than 10 years.

Hi, it is not clear from the message, if a movement occurs, will the battery data transmission interval be saved? -

Project completed. I've just now uploaded the files for version 607. I've tested this board, and it works.

Because this is a compact design, the battery clips may touch. So, to prevent any short-circuiting, you may wish to use a bit of Kapton tape, or similar insulating tape (maybe even electrical tape) on the outside of the inside clips to prevent contact with the outer clips):

I've just now uploaded a demo sketch whereby the PIR reports its voltage as a heartbeat once every 5 minutes. However, if motion is detected, it's immediately reported wirelessly.

I just now uploaded version 604, which uses an LDO better suited to meet the current requirements of the BT832X, in case that is installed. I have shipped the files to the fab, so I'll post an update after I've received and tested the board.
I expect that upgrading to use the nRF52840, when it becomes available, will be a simple drop-in replacement upgrade.

I just now uploaded version 603, which includes a 32.678KHz crystal oscillator.
