 We want to collect data from sensors and then periodically send packets of data. When we do not want to do this at a high frequency, we have some dead times. This leads to high energy consumption, which can have a significant impact on the battery life of sparrow when it is powered by a battery.
+You can download SleepLibrary code from [[https://github.com/TheodorUngureanu/SparrowV/tree/master/SleepLibrary|here]].
+Bellow you can see and example on how to use sleep library.

+/* This is an example for SparrowVSleep library.
+    You need to call SparrowV_SleepInit function.
+    The funciton has 2 params.
+st param: integer (> 1 second, greater than 1 second) (represent time in seconds, how long the board will sleep)
+nd param: bool (true - with data retention, false - with no data retention)
+               In case of no data retention the board can sleep max 8 secons and it will
+    reboot after time end.
