Incredible. The "yeah it's a hobby" terrain has been left far behind.

It might be possible to power the Arduino off the output pin. Since they are dirt cheap I would just test it. But like the others I would suggest to use the interrupts of pin 2 and 3. For my battery powered 3.3v pro mini I use 3.3v pir sensors without the voltage regulator. The standard 5v pir needs at least 4.5v just to step it down internally to 3.3V. On these I had problems with voltage stability because I stepped it up to 5V. Also the battery lifetime was poor. With the 3.3v pir version this thing runs for months. With the solar panel on top maybe forever.

@NeverDie Perhaps but the design is a bit too simple and unoriginal. I'd have to clean up the files a bit and I haven't touched Eagle since I made this board several years ago.

The product listing for the step-up that the OP is using says: Sucks the juice out of your batteries. Sounds like it delivers on what it promises....

What is the max ampere capacity of 3.3V battery it can charge ? Is there any upper limit like 1000mAh or 3300mAh like that ?
