Hi,
I would like to put Arduino into sleep and wake up to collect data every 5min.
Is it possible to implement the wake up interrupt with DS1307?
Thanks.

Yes.
AS far as I know DS1307 doesn't has alarm, only the 1Hz signal, but I wil be happy to discover to be wrong.

The OP didn't ask about an alarm signal. It's possible to use the 1Hz signal to wake the ATmega every second and go to sleep again for another second if the check of the time did not show the need to do something. It's also possible to use the internal watchdog timer to wake up once every 8s and check the time.
