Sleep and Low Power

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 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.
    1st param: integer (> 1 second, greater than 1 second) (represent time in seconds, how long the board will sleep)
    2nd 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.
#include <SparrowVsleep.h>
void setup() {
void loop() {
  // put your main code here, to run repeatedly:
  Serial. println("****************************");
  //sleep for 25 seconds with data retention
  SparrowV_SleepInit(25, true);
  Serial. println("****************************");
  Serial. println();
