This module is an upgraded version of the PZEM-004T with frequency and power factor measurement features, available at the usual places. It communicates using a TTL interface over a Modbus-RTU like communication protocol but is incompatible with the older [@olehs](https://github.com/olehs) library found here: [https://github.com/olehs/PZEM004T](https://github.com/olehs/PZEM004T). I would like to thank [@olehs](https://github.com/olehs) for the great library which inspired me to write this one.

# Common issue:
Make sure the device is connected to the AC power! The 5V only power the optocouplers, not the actual chip. Also please be safe, AC is dangerous. It can cause more serious issues, such as death. You are responsible for your own stupidity. So don't be stupid.
