AC Digital Multifunctional Meter Watt Power Volt Amp TTL Current Test Module PZEM-004T for Arduino

This module is mainly used for measuring AC voltage, current, active power and active energy, the module does not have display function, the data is read through the TTL interface.

Features:
Electrical parameter measurement function (voltage, current, active power, energy).
The reset function of energy key.
Can store data when power off (store the accumulated energy before power off).
PC display function (display voltage, current, active power, energy).
Serial communication function (with TTL serial interface itself, can communicate with a variety of terminal through the pin board, read and set the parameters).

Note:
1. This module is suitable for indoor, please do not use outdoor.
2. Applied load should not exceed the rated power.
3. Wiring order can't be wrong.
4. This module is equipped with TTL serial data communication interface, you can read and set the relevant parameters via the serial port; but if you want to communicate with a device which has USB or RS232 (such as computer), you need to be equipped with different TTL pin board (USB communication needs to be equipped with TTL to USB pin board; RS232 communication needs to be equipped with TTL to RS232 pin board).
