PZEM-004T is the best for the purpose of the DIY project, where we need to measure the voltage, current and power using Arduino/ESP8266/Raspberry Pi like opensource platform. In many electrical projects, engineer directly deals with measurements with few basic requirements like
- High galvanic isolation
- Parameter display
- Direct communication with computer
- Data acquisition and storage with subsequent viewing or copying to the computer.
This module serve all these basic requirements of measurement PZEM-004T as a separate board. The physical dimensions of the PZEM-004T board is 3.1×7.4 cm, The pzem-004t module is bundled with 33mm diameter current transformer coil.
- Measuring consumed electricity
- Serial interface UART with a speed of 9600
- Supply voltage 5V
- The possibility of connecting LCD or LED displays
