This project is an IoT-based Smart Street Light system developed using ESP32, LDR sensor, and relay module. The system automatically turns street lights ON and OFF based on ambient light intensity and sends real-time data to the cloud using ThingsBoard.
The objective of this project is:
To automate street lighting system
To reduce electricity wastage
To monitor light intensity remotely using IoT dashboard
ESP32 Microcontroller
LDR (Light Dependent Resistor)
1-Channel Relay Module
LEDs (Street Light Simulation)
Resistors (220Ω)
ThingsBoard IoT Platform
LDR detects surrounding light intensity.
If light intensity is low (night time), relay turns ON the street lights.
If light intensity is high (day time), relay turns OFF the lights.
Sensor data (LDR value and light status) is sent to ThingsBoard.
Real-time graphs and indicators are displayed on dashboard.
