Peacefair PZEM-004T AC 80-260V 100A Multifunction Electric Power Energy Metering Communication Module with CT Coil

The Peacefair PZEM-004T is a widely used AC energy monitoring module designed for accurate measurement of key electrical parameters—voltage, current, active power, and energy consumption—in single-phase power systems. Ideal for IoT, smart energy projects, and electrical diagnostics, this compact module offers high precision and easy integration with microcontrollers like Arduino, ESP32, Raspberry Pi, and more.

Equipped with a TTL serial communication interface, the PZEM-004T allows seamless data transfer and parameter configuration through USB (with a TTL-to-USB converter) or RS232 (with a TTL-to-RS232 adapter). Its lightweight form factor, wide voltage support, and high current capacity (up to 100A) make it perfect for home automation, industrial monitoring, and smart metering applications.

✅ Key Features:

• 📏 Multi-parameter Electrical Monitoring: Measures AC voltage (80–260V), current (up to 100A), active power, frequency, power factor, and energy (kWh).

• 🔄 Power-Down Data Retention: Stores energy consumption data even after a power failure.

• 🆓 Built-in Clear Button: Easily reset the energy counter via onboard button.

• 💻 TTL Serial Communication: Communicate with PCs or microcontrollers for real-time data logging, parameter setting, and remote energy tracking.

• 🔌 Plug & Play with CT Coil: Includes a Current Transformer (CT) sensor for non-intrusive current measurement—simply run the load wire through the coil.
