The PZEM module is a versatile and powerful tool used for monitoring electrical parameters such as voltage, current, active power (kWh), and frequency in real-time. It is specifically designed for integration with smart energy meter, providing valuable insights into the performance and health of energy meter. The module communicates with a microcontroller, such as an ESP32, through a serial interface (RS485 or UART) to collect data from connected sensors. In this application, the PZEM module interfaces with an LCD display and a website display to show real-time data, allowing users to monitor energy meter  parameters on both local and remote platforms. The LCD provides immediate feedback on key electrical parameters like voltage, current, active power, and frequency, offering a convenient and compact solution for localized monitoring. Additionally, the website display enables remote monitoring, accessible from any device with internet access, using a web-based interface. This can be achieved through the integration of IoT devices, such as ESP32 controller, which send collected data to a cloud server or web platform. The energy meter monitoring system aims to enhance energy management, ensure power quality, and optimize consumption by providing accurate and real-time information. It can be used in various applications, such as solar power systems, industrial facilities, and residential energy monitoring, making it an essential tool for users seeking to improve grid performance, troubleshoot electrical issues, and reduce energy waste. The combination of real-time display and remote monitoring ensures greater control over energy resources, thereby contributing to sustainability and cost savings.
