PZEM-004T-100A V3.0 AC Single Phase Multifunction Ampere Meter Power Energy Monitor Module

Description

The PZEM-004T-100A V3.0 is a high-precision AC single-phase multifunction energy monitoring module designed to measure and monitor electrical parameters in real time. It can accurately measure AC voltage, current, active power, power factor, frequency, and accumulated energy consumption, making it ideal for energy monitoring, smart home systems, industrial control, Arduino projects, and IoT applications. This version uses an external split-core current transformer (CT clamp) capable of measuring up to 100A without requiring direct connection to the high-current line. The split CT design improves safety and makes installation easier because the clamp simply clips around the live wire. The mod
