hi
im trying make arduino, takes co2 measurements 1x or 2x day, go sleep rest of day until next day.
i've read lowpower library , external interrupt option im trying decide. im not sure make go sleep whole day using lowpower, @ least not without external interrupt.
i think understand need put sleep , setup interrupt such using rtc module, @ 5am each day example, rtc send interrupt arduino , wake up?
