getting value of sensor each second c++

Question

I am recently trying to store data measured by my humidity sensor into my MYSQL database. I have already programmed the necessary C++ pogramm getting the data from the sensor, storing it in my MYSQL database and getting the current UnixTime as well.

However, I´d like to store the data each second and think using a thread does not seem a neat solution for this problem. I also do not want MYSQL to insert the UnixTime automatically. I´d like to keep on using my C++ programm for that.

Does anybody know an easier approach to store the data each second with the necesarry UnixTime using C++?

Threads are actually a neat solution for background tasks. Consider this example:

#include <iostream>
#include <thread>
#include <chrono>

void everySecondTask() {
  while (true) {
    // Do actual work here, e.g. get sensor data and write to db
    std::cout << "second passed" << std::endl;

    std::this_thread::sleep_for(std::chrono::seconds(1));
  }
}

int main() {
  // operations and sleep in everySecondTask is done in different thread, code
  // in main is not paused.
  std::thread background(everySecondTask);

  // do you 200 lines of code here, while task is called every second

  background.join();
}
