Particle Photon with PZEM004T

Hi: Everyone.

I want to ask u all how to connect particle photon with PZEM004T module.
I try to develop smart meter with particle photon…
Plz reply me…

In basic research this module is dangerous to use - proceed with a lot of caution!

@Yapno, I would recommend a board which uses clip-on current transformers instead of closed ones. The PZEM004T also draws its power directly from the measured circuit which is why @shanevanj is concerned about safety. Such a device is not isolated and invariably dangerous. I highly recommend a device that is independently powered.

Take a look a the Open Energy Monitor site for inspiration.


Another ideas to use modules which is designed for photon
