Irrigation valve control system

[Gabriel61]

The problem is like
Irrigation control of a garden from 2 km distance.
Need simple setup.
Using humidity and light sensor inputs.
For communication Lora 1278 is better or any other better option?
I’m doing it with arduino.
Is it possible with some simple microcontroller like any 8 bit, because the target is to reduce cost and improve resilience.

Is it possible with some simple microcontroller like any 8 bit, because the target is to reduce cost and improve resilience.

Obviously, as that's all an Arduino is anyway, a development board (usually) using an 8 bit AVR processor.

You can develop using the Arduino, then replace that with an AVR processor (and associated components).

Or use a different processor entirely, and go from there - as with many people, and vast numbers of commercial projects, I mostly use PIC processors, but dabble with Arduino as well. For a completed project, rather than use just a bare processor (plus bits), I usually use an Arduino mini - https://docs.arduino.cc/retired/boards/arduino-pro-mini - as everything you need is on there, and they are available ridiculously cheaply.
