ESP32 Power Monitor and Control IoT Unit – Single Phase

The ESP32 Power Monitor and Control Unit is a compact, high-performance power sensing and control platform designed for developers, researchers, and product engineers. It serves as a robust hardware foundation for building custom IoT, energy management, research, data collection and electric vehicle (EV) charging solutions.

This unit integrates an ESP32 chip for processing, a Current Transformer (CT) for current, voltage, and power measurement, an AC relay for load control, and an LCD display for real-time data visualization. It enables users to connect sensors and actuators, and to develop their own firmware and applications for real-time monitoring, control, and automation.
