Hi I am building my home alarms systems. what is the solution to read 12V analog inputs with an arduino ? I don't want to use a resistor dividers circuit, is there a hat card or a solution to plug 12V analog input and be able to process it with arduino? I need about 4 analog inputs for 4 alarms …

If there is such a solution, it will probably use voltage dividers!
