help me please

Hello People I am new to this forum
I would be happy if you could direct me.
I'm doing a project with arduino uno with lora module The goal of the project is to create a network of wireless sensors for detecting fires I have arduino with lora and it is connected to temperature sensors via lora It sends the data input from the sensors to arduino getway that uploads it to a web server
I have a number of my questions:

  1. How ardinuo getway supposed to cost the data to the server? , I would be happy to have a good guide
  2. I want my site to be real-time and update me, meaning I want to display a map of Google and have a point where arduino lora with temperature sensors is how I do it.
    May God bless you, thank you to anyone who tries to help me
