About PZEM-004T energy meter
The PZEM-004T is a high-precision AC multi-function electric energy metering module designed for real-time monitoring of electrical parameters. It measures AC voltage, current, active power, and energy consumption with high accuracy. The module operates on a wide voltage range of 80-260VAC and supports a rated current of 100A (when paired with the included 33mm CT coil). It features a clear LCD display for local readouts and a TTL serial communication interface (UART) for integration with microcontrollers like Arduino, ESP32, or Raspberry Pi. This makes it ideal for smart home energy monitoring, industrial equipment power analysis, and DIY electronics projects. Its compact design and easy-to-use interface allow for quick deployment. Choose this module for reliable, real-time power monitoring without the complexity of designing a measurement circuit from scratch.
