PZEM-004T V3 - 100A Energy Monitor - Digital Multifunction Meter - Watt Power Volt Amp Current Test Module - Modbus

An electrical monitoring and test module that can be used to test power, energy, voltage and current, and then displayed on a computer or other terminals. It can store data when power off, and store accumulated energy data before power off. Designed with one-button reset, you can reset energy data by simply pressing one button. The TTL serial port can communicate, read and set parameters with various terminals through the RS232 adapter.

PZEM-004T

AC communication module, the module is mainly used for measuring AC voltage, current, active power, frequency, power factor and active energy, the module is without display function, the data is read through the

TTL

interface. Functions: 1. Measurement of voltage (V), current (A), average power (kW), energy (kWh). 2. Energy reset by pressing one button. 3. Data saving after power off (saving accumulated energy data before power off). 4. PC display function (display voltage, current, average power, energy). 5. Serial port communication function (TTL serial port can communicate, read and set parameters with various terminals via USB adapter).
