This project presents an IoT-based intelligent street light monitoring system designed to detect lamp failures, short circuits, and abnormal current conditions in real time.

The system consists of multiple sensor nodes (Node-1, Node-2) installed near street light poles and one main control unit. Each node uses an ESP32 microcontroller to monitor:

Light intensity using LDR sensors

Electrical current using INA219 current sensor

Short circuit and overcurrent conditions

The sensor nodes communicate wirelessly with the main ESP32 using ESP-NOW protocol. The main controller hosts a web dashboard that displays real-time status of all street lights including:

Current consumption

Individual lamp failure

Complete pole failure

Short circuit detection

Node offline status
