Wiring Diagram with NodeMCU

The above diagram shows how the CT Sensor, Multimeter and Node MCU devices are connected to each other in relation to the entire system. The above clearly shows how the data coming through the CT Sensor is connected to the Multimeter and then to the Node MCU. The multimeter and CT Sensor have several pins. They are interconnected. The CT Sensor has several main pins such as Gnd, Tx, Rx, and 5V. Rx and Tx are used to communicate with the[7] host computer where the object code being compiled is downloaded. PZEM-004T V3 and ESP-32 Node MCU are communication works on different voltage level theoretically but in practical life 3.3V Node MCU pins have tolerance of 5V. VU pin is USB 5V pin (only works when Node MCU powered through USB) Although, Node MCU has 11 pins. Of these, two pins are separated by Rx and Tx, leaving nine more. They are called I/O pins. They are named from D0 to D8. As mentioned above, the multimeter is only connected to a few pins on the Node MCU. They are Gnd, D6, D5 and 5V. The Gnd pin on the CT Sensor connected to the Node MCU itself. Also, the pin Tx is connected to the pin D5 of the Node MCU. The pin Rx in CT Sensor is connected to the pin D6. The 5V voltage supplied by the CT Sensor is connected to the 5V of the Node MCU itself.
