I tested the device by skipping a wire and connecting a regular AA battery - it clicks with a relay.

you need to take care of histeresis becouse ralay can be chattering. your pcb should have regulated delay on relay. high currents can couse fire or damage relay becouse od this. watch out.

Tested at a load of 4A, sufficient wire without additional twists, used for monitoring the heating element. When connected through two modules, the normal operating mode and the mode with increased current consumption will be visible. The sensitivity is very well adjustable - when connected to a main load of 4A and an additional load of 50W, it performs excellently.
