Power Saving Street Light Using Advance Sensors

Abstract

The present street light control system is based up on the manual control of the lights. The existing system is commonly used in all streets of street light system. But in this method there is a loss of heavy electricity in the whole night. If the street light is not stopped after the night, the loss will continue throughout the day. And also the street light is not necessary when there are no human and vehicle movements in the street. In this project developed a power saving street light using advance sensors. This system mainly consists of light sensor, PIR sensor, vibration sensor and microcontroller. Sensors are connected to the microcontroller. Vibration sensor is used to detect the vehicle movement. PIR sensor is used to detect the human movement. Microcontroller generates the control signal, to on/off the street light according to the output of the vibration sensor and PIR sensor. Micro controller output is given to the relay. Relay operates the load according to the microcontroller output. Further the light sensor is used to sense the light intensity. The light will be automatically switched on when the intensity of sun light is low and the light will be automatically switched off when the intensity of sun light is high. In power saving street lights a system is designed through which we can save the electricity of the street light on the highways using the microcontroller.
