PZEM Current and Voltage Reader

PZEM Current and Voltage reader is a module that can read current, voltage, and power in a simple application. It also comes with RS485 Serial Protocol so that you can read and pass the data to your microcontrollers or even computers. It PZEM Reader comes in two variant:

• PZEM-004T AC Voltage and Current Reader
  • 100A CT Clamp included
• PZEM-017 DC Voltage and Current Reader
  • 50A Shunt Resistor included

PZEM-004T AC Voltage and Current Reader
