Peacefiar Pzem-004T Ac Elec Energy Power Monitor P004T

1. his Peace fair PZEM-004T Multi-function AC Power Monitor is very popular in electrical consumption measurement projects.
2. It is capable of measuring four interrelated electrical variables as voltage, current, power, and energy. 
3. This tiny PZEM-004T circuit is great for measuring AC (RMS) voltage, current, and power (single-phase). The unit easily interfaces with Arduino and other hardware using the code library.
4. Simply power the board with a power supply (or you can use the AC source you are measuring) and connect the circular sensor to the board.
5. Run the wire through the circular sensor and you`re ready to start measuring the voltage, current, and power. The circuit also comes with a TTL to USB adapter wire for easy connection to a computer or microcontroller.
6. This module features a 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 a computer), you need to be equipped with different TTL inboard (USB communication needs to be equipped with TTL to USB pin board; RS232 communication needs to be equipped with TTL to RS232 pin board)
