When AC power is turned on, the white framed area should not be touched due to high voltage being present. Electricity is dangerous and a shock can be fatal. Always take note of safety when working with electricity. It is strongly advised that you make use of your local qualified electrician when working on AC projects.
This module can be used to detect if your 220V AC connection is on. A small microcontroller like Raspberry Pi Pico or Arduino can be used for instance to monitor and report loadshedding or tripped circuit breakers. Your microcontroller would have to have it's own backup power though.
