The Peacefair PZEM-051 is an inexpensive, compact DC/AC energy meter module commonly used for monitoring voltage, current, power, energy, frequency, and power factor in DIY solar, battery, inverter, and bench-test setups. It’s often seen in 12–48 V DC and single-phase AC projects paired with microcontrollers (Arduino, ESP32, Raspberry Pi) via a serial (TTL) interface. This section is a direct interpretation of the

Unlike its popular cousin (the PZEM-061) which uses a split-core current transformer (CT), the is typically designed for DC circuits or high-current AC systems using a shunt (external resistor). It measures Voltage (V), Current (A), Power (W), and Energy (kWh/Wh) with a backlit LCD.
