I 'm designing a smart switch remote controllable for home automation.
I want add the capability of detecting short circuit and human body shocking protection to this single relay (of e.g. a lamp).
I mean when the circuit detect that (1) there is a short circuit in the side of lamp, or (2) live line (220v) is connected to a human body, A buzzer is alarmed and the power is break.
Hope you can understand my purpose.
Could you please suggest me a circuit or ideas to do that?
