The Street Light Monitoring via Bluetooth project is designed to remotely monitor and control street lights using a smartphone. Through a Bluetooth-enabled microcontroller system, the user can turn lights ON/OFF, check their status, and detect faults without manual inspection.

This system improves energy efficiency, reduces maintenance efforts, and ensures safety by enabling real-time monitoring of multiple street lights.

Parts Used:

1. Microcontroller (Arduino / ESP32 with Bluetooth) – Central control unit
2. Bluetooth Module (HC-05 / Inbuilt ESP32 Bluetooth) – Wireless communication
3. LED / Street Light Model – Load to be monitored and controlled
4. Relay Module – Switches street lights ON/OFF
5. Smartphone with Android App – User interface for monitoring
6. Sensors (optional: LDR, current sensor) – For automatic control and fault detection
7. Power Supply (Battery/Adapter) – Runs the system

Advantages:

1. Remote Monitoring – Control street lights from a smartphone
2. Energy Saving – Lights can be managed as per requirement
3. Low Maintenance – Quick fault detection without manual checks
4. Cost-Effective – Simple setup compared to GSM/IoT systems
5. Scalable – Can be expanded for multiple lights in smart cities
