Is a .NET Core app working with sensors the right way?

Question

linux

How to properly implement the following architecture:

A computer with Ubuntu Desktop 18.04 on board
Loading a .NET Web API application (.NET Core 2-3 is not important)
The same application reads data from various sensors, controls a couple of servos, etc.

An example of architecture is shown in the figure:


How to organize all this correctly?

My version is to start the timer when loading the application and do all this work with pieces of iron in the callback.

Answer 1

I would just write to files and read from them.
ls /dev
and man for each device.

Answer 2

Application is when colored paper is cut out with scissors and the pattern is assembled with glue.
I would break the application into 2 parts, the service that actually collects the data, and the webapi itself. Working with the equipment is unknown how time will go, and web requests have a time limit, of course it can be made large, but this is not it. And the interaction can also be done through sockets or through dbus.
