This video demonstrates how to build a DIY energy consumption monitoring system using an ESP32-CAM module to count LED pulses from your electricity meter. Learn how to configure a TTGO T-Camera board to detect and record flashing pulses—tracking until you reach 160 flashes, which equals 1 kilowatt-hour of consumed energy. We'll walk through the complete hardware setup, including using a PWM-controlled LED with a potentiometer to simulate meter pulses for safe testing without accessing your actual electricity meter. The project leverages the ESP32's built-in OLED display and integrated web server to provide real-time visualization of pulse counting, allowing you to monitor energy usage both locally on the device screen and remotely through any browser on your Wi-Fi network. Perfect for home automation enthusiasts looking to accurately track electricity consumption with an affordable, customizable IoT solution.
