Smart AC Energy Meter with Voltage Protection Feature Using ESP32 & PZEM-004T

Learn how to build your own Smart IoT AC Energy Meter using an ESP32 and the PZEM-004T V3.0 module! In this DIY IoT project, I'll show you how to set up a complete energy monitoring system with real-time tracking and advanced safety features. This custom smart meter doesn't just track your energy usage—it actively protects your appliances. It accurately measures voltage, current, power (watts), and total energy consumption (kWh). Plus, I've integrated an automatic relay control system that provides over-voltage and under-voltage protection to keep your home electronics safe. Whether you're looking to monitor your home power consumption, build a smart grid project, or learn more about ESP32 home automation, this step-by-step tutorial covers everything you need to know. 🔗 Links & Resources: Circuit & Source Code: https://circuitdiagrams.in/shop/smart... 🚀 Key Features: 📊 Real-time Voltage, Current, Power & Energy Monitoring 🌐 WiFi-based Web Dashboard (ESP32 WebServer) ⚡ Over Voltage Protection (OVP) 🔻 Under Voltage Protection (UVP) 🔌 Automatic Relay Trip & Restore System 📱 Remote Monitoring from any device 💾 EEPROM / Preferences Data Storage 🔔 Buzzer Alert for Fault Conditions 🛠 Hardware Used: • ESP32 Development Board [https://amzn.to/4rI7tUp] • PZEM004T v3.0 Energy Meter Module [https://amzn.to/47hH6x8] • 2-Channel Relay Module [https://amzn.to/3NwDuRg] • 20x4 I2C LCD Display [https://amzn.to/4dzZG7p] • Buzzer [https://amzn.to/4bGbpyM] • Veroboard PCB [https://amzn.to/4bWwo1z] • Power Supply Module [https://amzn.to/4tl2mL9] 📌Another IoT Smart Energy Meter Using ESP8266 & PZEM-004T:    • IoT Smart Energy Meter Using ESP8266 & PZE...   📸 Gear Used: Camera: Sony Alpha ZV-E10M2K (16-50mm Power Zoom Lens) [https://amzn.to/4rePypn] Tripod: DIGITEK DPTR 895VD [https://amzn.to/42y7Cjd] This project is perfect for IoT enthusiasts, electrical engineering students, and anyone interested in smart energy monitoring systems. ⚠️ Important: This project involves AC mains voltage.
