- 4. INTRODUCTION We need to save or conserve energy because most of the energy sources we depend on, like coal and natural gas can’t be replaced. Once we use them up , they are gone forever. Saving power is very important, instead of using the power in unnecessary times it should be switched off. In any city “STREET LIGHT” is one of the major power consuming factors. Most of the time we see streetlights are on even after sunrise thus wasting lot of energy. Over here we are avoiding the problem by having an automatic system.

- 5. OBJECTIVES • to design an automatic streetlight that works in conventional energy resources • Using LDR we control the street light, when the LDR value falls above the threshold value the lights are switched on and when the value falls below the threshold value the lights are switched off . • to save and conserve energy in an efficient way an intensity controller.

- 11. COMPONENTS DESCRIPTION • LDR : Light Dependent Resistor as the name suggest the resistance is dependent upon the light incident on it. The light dependent resistor resistance changes with intensity of light, with increase in light intensity the resistance offered by the sensor decreases and with decrease in light intensity the resistance offered by the sensor increases. Hence it acts as variable resistor with change in light intensity. These helps in finding the amount of light intensity at that instant of time and thus helping in regulating the lighting of our lighting system accordingly.

- 12. COMPONENTS DESCRIPTION • ARDUINO: Arduino is an open-source physical platform based on microcontroller board having the ATmega32 series controllers and Integrated Development Environment for writing and uploading codes to the microcontroller. It has input and output pins for interaction with the outside world such as with sensors, switches, motors and so on. To be precise it has 14 digital input/output , 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller .It can take supply through USB or we can power it with an AC-to-DC adapter or a battery Arduino acts as the processing module of the system. It takes input from the LDR, process the data and gives the output to LEDS or through a transistor mechanism. REJVI AHMED, Dept. of Mechanical Engineering, IUBAT 12
- 13. Components Description • Resistor: Resistor is an electrical component that reduce the electric current. Capacitor: A capacitor is commonly used for filtering and store charge in it. Diode: A diode is an electrical component that conducts current in one direction and blocks current from flowing in the other direction. REJVI AHMED, Dept. of Mechanical Engineering, IUBAT 13
- 14. Components Description • Transformer: The voltage would down by the transformer. The working principle of transformer is very simple. It depends upon Farada’s law , mutual induction between two or more winding is responsible for transformation action in an electric transformer. • Transistor: A transistor is a device that regulates current or voltage flow and acts as a switch or gate for electronic signals.

- 17. CONCLUSION This Arduino based project will provide a competent method for lighting systems and make the whole process of energy saving easier and efficient. With a capability to change the amount of light emitted depending upon the outside condition is no doubt an innovation with many future application apart from the fact that it can also be used in many present day tech such as street light, park lights, industrial lights and many more. The usage of the smart lighting system will undoubtedly change the world that we see today REJVI AHMED, Dept. of Mechanical Engineering, IUBAT 17
