SEASON BASED STREET LIGHT SWITCHING BASED ON SENSORS
INTRODUCTION
The important consideration in the present field of Electronics and Electrical related technologies are Automation, Power consumption and cost effectiveness. Automation is intended to reduce manpower with the help of intelligent systems and Power saving is the main consideration forever, as the source of the power(Thermal, Hydro etc.,)are getting diminished due to various reasons .
The main goal of our project “SEASON BASED STREET LIGHT SWITCHING BASED ON SENSORS” is to control the switching of Street Lights automatically according to the Light Intensity. This allows us to realize the task efficiently and effectively without the intervention of human by making it automated.
This project is designed around a microcontroller which forms the heart of the project. In our project we are going to make use of a sensor called LDR, which stands for ‘Light Dependent Resistor’, which senses the intensity of light. And accordingly the street lights are made ON and OFF. The LDR is interfaced with microcontroller.
The control unit consists of a microcontroller with its associated circuitry. According to our project, the Street Lights are made ON and OFF according to the Light Intensity. The hardware involved in the project is Power supply, Microcontroller, LDR and bulb.
