通常,对于220VAC,I系列使用2x470K 1/2W。理论上,一个1M 1/2也可以工作,但是你没有那么孤立……我实际上从未使用过“真正的”ZCD模块,而只是一个标准输入引脚:但是我想电子规格应该是SAMP。PS:有时,输入引脚上的10NF电容有助于“稳定性”。

Usually, for 220VAC I used to use 2x 470K 1/2W in series. In theory one single 1M 1/2 works too, but you have less isolation then...
I actually never used the "true" ZCD module, rather just a standard input pin: but I suppose electrical specs should be the same.
PS: at times, a 10nF capacitor at the input pin helps "stability"
