Hello,

I need to record temperature & humidity over days with a sample frequency of 15 minutes.

Since the PIC will be battery powered, I think about putting it to SLEEP until the next sample record happens.

According to my PIC's data sheet (16F88 - 4MHz), the TMR0 won't be able to wakeup during SLEEP mode.

What is the best way to time the PIC for long sleep periods?
