Using multiple PZEM sensors

Hi There,

Apologies for bumping up an old thread. Any chance I can connect more than 2 PZEM using software serial sketch? I am looking at measuring 3-phase systems including 1 neutral. My project is for datalogging for power panel installed inside the isolation room for covid-19 patients.

Thank You


I’ve move your post to a new topic.

Yes, multiple PZEMs can be used together. Various methods are discussed in this topic…
