How to make a household power overload alarm?
I haven’t found anything like it anywhere. I would like to make a sound alarm network load (preferably adjustable). So that it trips when the current value is close to the tripping current of the circuit breaker. Very useful thing. In the event of a trip, it is possible to reduce consumption and prevent the circuit breaker from tripping. Sometimes the machine knocks out several times a day, when the wife turns on everything that is needed and not needed. Most acquaintances have the same problem. Can someone tell me a solution.
Hello! In general, such a project can be implemented using a current transformer and a microcontroller, it is also possible on operational amplifiers, well, or on logic. In addition, it may be easier to implement using a current relay, a 12V power supply and a gramophone from a car alarm. They gave you the direction, I think you will master the project yourself.
