Abstract: This project presents a street light detection system using Arduino, LED, LDR (Light Dependent Resistor), IR (Infrared) sensors, resistors, and a breadboard. The aim of the project is to automate street lighting based on the ambient light conditions, thereby optimizing energy consumption and enhancing safety. The system utilizes LDRs to measure the ambient light intensity and IR sensors to detect the presence of vehicles or pedestrians. The Arduino microcontroller processes the sensor inputs and controls the operation of the streetlights accordingly. The system incorporates a breadboard for easy prototyping and connectivity. Upon detecting low ambient light levels and the absence of vehicles or pedestrians, the Arduino triggers the LED street lights to turn on. Conversely, when the ambient light levels are high or a vehicle or pedestrian is detected, the Arduino instructs the LEDs to turn off, conserving energy and reducing light pollution. To ensure accurate light detection, appropriate resistors are used to calibrate the LDRs and IR sensors. This allows for precise measurement and detection thresholds, enhancing the reliability of the system.
