PZEM-004T AC Power Meter with 100A Current Transformer

Measure electrical values in a compatible monitoring or maker project with the PZEM-004T multifunction meter module. Product details cover AC voltage and current measurement with serial communication.

Electrical monitoring for compatible builds

✅ Read several electrical values — the module is described as a voltmeter, ammeter and wattmeter.

✅ Connect readings to a controller — UART-to-TTL serial communication and Modbus-RTU are specified.

✅ Choose a current-sensor option — variants include different CT options, so check the selected version.

Use the module where a project needs to read AC measurements and send them to a controller. Product details specify an 80–260V range and up to 100A current measurement, with values depending on the selected sensor option.

This is a component module, not a finished consumer meter or certified installation. Work with mains voltage only if qualified, and verify wiring, isolation and the exact CT supplied for the selected variant before use.

Specifications: PZEM-004T; AC 80–260V specified; up to 100A specified; UART-to-TTL; Modbus-RTU. CT configuration varies by selected option.

Confirm the sensor variant and electrical requirements before integrating it.
