Hi Jens, That's how I did it on my concept board, with an external interrupt. Problem is that I need more components to be able to generate the interrupt and believe it or not, it actually used more current. Standby mode means the processor is in sleep mode but wakes up about 8 times per second to check the sensor. The sensor only uses 2uA but the processor uses more current in sleep than in deep sleep mode, so all together it is 10uA.
In deep sleep, the processor is completely powered down, only the RTCC continues running. It can only be awakened by an external interrupt (push button rather than motion sensor).
