It has been a while (mainly because the PIR was out of order for other reasons) but now I am restarting the project and again it happened that the PIR no longer responded. So I took a look at your code, but it seems your are using a BH1750 light sensor, is that correct? And are you using that in fact at the moment, or did you switch to LDR and is this perhaps not the latest version of the code?
Thanks!

@gijss the code can be found here. But I don't know the actual status of this code as I have not used it for a while and I was busy creating a dimmer. But maybe you can copy parts out of it.

@dynamite Thanks for the code, I am sure it will prove to be useful. Will try to experiment this weekend. Can you also share how you connected the LDR to the arduino? I have the feeling I might be using a suboptimal wiring scheme (or wrong resistor) resulting in shorter battery life.
I have build a couple of these and they work fine. Replacing batteries with the baseplate is really a huge advantage, and battery life seems to be pretty good.
I have one issue though: I have built one including an LDR. But this seems to freeze after a random time, no longer reacting to movement.
@dynamite , can you may be share your code and the way you have attached your LDR to the arduino etc?
Many thanks!
