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
Warranty Period: 12 months
