Tell about a multithreading task: what problem was solved and how?

In one of the projects for IoT devices, there was a task of parallel data collection from multiple sensors and simultaneous processing of this data without blocking the main thread.

The problem was that sensors operated at different speeds and could delay each other, leading to data loss or delays.

Solution:

• Used multithreading with RTOS or OS threads.
• For synchronization of access to shared resources, mutexes or semaphores were used to prevent data races.
• For data exchange between threads, message queues were used, which allowed buffering data and processing it asynchronously.

This approach ensured stable data collection and processing without mutual blocking and data loss.
