Electronic clock timer to periodic wake up a sensor

I actually need to be built an atmega328P ( or simpler ) as a timer to close a transistor gate to power a sensor.

The target is to wake up few seconds (measure + send data via 2.4 GHz arduino module ) each 6 hours (around ) and then go back to sleep.

I've linked the set up I've made, that actually works but sometimes the timer keeps awake.

Then I'd like to have a more stable solution.
