There are 3 inputs and these inputs are read on Arduino according to the adjusted voltage. As a result of this reading, it turns the system on and off with relay control with certain voltages. When a voltage of more than 65V is read from IN1, relay1 turns on and an IN1 high voltage alarm is given t…

How can I do that

How do You intend to detect those voltage levels?
AC or DC?
