Why doesn't the autorun of the program through rc.local work correctly when loading armbian?

Question

linux

I'm trying to organize the autostart of the program when starting Armbian on Orange Pi Lite via rc.local.
A simple program, dust_s, written in C, which polls the sensor via UART and writes information to a file, if run through the console, it works fine.
When writing the line "sudo /*full_path*/dust_s &" to rc.local, the program seems to run, but for some reason it does not write to the file. With what it can be connected?

Answer 1

Maybe it's worth it?
sudo /*fullpath*/dust_s >/dev/null 2>&1
