110V input sampling

Introduction: According to the needs of a certain Party A’s father, the device has a 110V voltage signal input. Initially, I thought that 110V was a level signal, and I planned to use a relay to implement it. Later, Party A’s father sent me a request for 110V signal control, and I suddenly realized that it turned out that 110V needed to be processed by analog sampling.
