PZEM-004T AC MULTI-FUNCTION POWER MONITORING

The PZEM-004T AC Power Measurement Module is a multifunction AC power measurement module designed to measure AC voltage, current, active power, energy consumption (kWh), frequency, and power factor in single-phase electrical systems. It uses a current transformer (CT) clamp for non-invasive current measurement and communicates with microcontrollers through a UART (TTL/Modbus RTU) interface, enabling easy integration with Arduino, ESP32, STM32, Raspberry Pi, and PIC. The module provides high measurement accuracy, real-time monitoring, low power consumption, and reliable electrical parameter measurement, making it suitable for energy management applications. Due to its compact design and comprehensive monitoring capabilities, the PZEM-004T is widely used in smart energy meters, industrial automation, home energy monitoring, IoT-based power management systems, renewable energy systems, and electrical equipment monitoring applications.
