Energy efficient solar village with midnight load shedding using human sensor device is also known as an automatic solar street light control system which is used in modern world for energy savings using Light dependent Resistor (LDR) and motion sensor. Nowadays the human has not enough time, and he/she is unable to find time even to switch the lights ON or OFF. This new system can be used more effectively in case of street lights. In proposed system, the street lights will be switched on just before the sun sets and are switched off the next day morning when there is sufficient light on the road. The proposed model also uses motion sensor to control the intensity of light. Huge power is consumed when most the vehicles don’t move during the late. This work was carried out to shows that the proposed System is relatively low cost, efficiency is better than the existing system.

CHAPTER ONE
1.0 INTRODUCTION
1.1 BACKGROUND OF THE STUDY
The idea behind the design of this system is to make available the require illumination in our roads for night time events, security, and beautification. This goes a long way in helping to curb the problem frequently encountered as a result of darkness during night time such as thieves, arm robbers operations or wide animals approaching our homes during night hours.
A street lighting is any electrical lighting that is fixed outside house for the illumination of such environment or a Street light is a raised source of light on the edge of a road or walkway, which is turned ON or lit at a certain time every night.
Many of the people have a phobia of darkness, so to assist them in such situation; we have explained a simple circuit. This device switches street lights on detecting vehicle movement and remains off after fixed time [16].
.
In 21st century it is quite impossible to avoid accident during night without lights. So street light is the essential part in our busy life for safety purposes. But the man power required for controlling the light cuts a huge cost. So in this situation this project helps to reduce the cost of manpower and reducing power Consumption. During daytime there is no essence of street light so the LDR keeps the street light off. As soon as the light intensity is low then the LDR is started working and the light is switched on. Motion sensor has a huge indoor and outdoor application. Very common application of motion sensor is activation of automatic door opening. Motion sensor also used instead of convention sensor because of its accuracy. Motion sensor also used as an alarm when it detects the motion of a possible intruder [15].
1.2 PROBLEM STATEMENT
The existing solar street lighting control system used timer and photocell. The timer is set up to turn on the street light within 7.00 p.m. until 7.00 a.m. Meanwhile, photocell reacts based on the presence of light or electromagnetic energy. In a rainy day or when the light intensity is low, the photocell will energize the contact and automatically turn on the street lights. This system is quite inefficient since the condition of day and night is uncertain. Sometime sat 7.00p.m.the day is still bright but the street light is already switched on. In contrast, at 7.00 a.m. the street light is already switched off although the day is still dark. Thus, this system is quite inflexible. In order to surge the efficiency, a modern street lighting control system must be able to adapt the light level intensity to determine the optimum energy consumption level. However, power wastage will happen if there is no user or vehicles use that road especially in rural areas at midnight. This device was built to solve this problem by providing full (when an object is detected) and dim output when no output was detected. And it also has the capacity of switching ON automatically during sunset and OFF during sunrise.
1.3 AIM AND OBJECTIVES OF THE STUDY
The main aim of this work is to construct a solar street light that switches to full output light on detecting object or vehicle movement and dim level when no object vehicle is detected. It also has the capacity of switching ON during sunset and OFF during sunrise. The objectives of the work are:
- to build a solar controlled street light that is cost effective
- to save energy
1.4 SIGNIFICANCE OF THE PROJECT
Major significance of solar street lighting includes: prevention of accidents and increase in safety. Studies have shown that darkness results in a large number of crashes and fatalities, especially those involving pedestrians; pedestrian fatalities are 3 to 6.75 times more likely in the dark than in daylight. Street lighting has been found to reduce pedestrian crashes by approximately 50%.
Furthermore, lighted intersections and highway interchanges tend to have fewer crashes than unlighted intersections and interchanges.
Towns, cities, and villages use the unique locations provided by lampposts to hang decorative or commemorative banners.
In design of solar street light for industrial applications, ultrasonic sensors are characterized by their reliability and outstanding versatility. Ultrasonic sensors can be used to solve even the most complex tasks involving object detection or level measurement with millimetre precision, because their measuring method works reliably under almost all conditions [5].
No other measuring method can be successfully put to use on such a wide scale and in so many different applications. The devices are extremely robust, making them suitable for even the toughest conditions. The sensor surface cleans itself through vibration, and that is not the only reason why the sensor is insensitive to dirt. The physical principle—the propagation of sound—works, with a few exceptions, in practically any environment. Ultrasonic sensors have proven their reliability and endurance in virtually all industrial sectors when used in street light [5].
If the lighting system implements all LED lights, the cost of the maintenance can be reduced as the life span and durability of LEDs is higher than Neon based lights which are normally used as street lights.
As the lights are automatically turned ON or OFF, dim or full, huge amount of energy can be saved.
1.5 SCOPE OF THE PROJECT
Project deals with making a smart solar street light that would enable it full (100%) output on detection object (human being or vehicle) and dim (60%) output when no object is detected using PIR as the sensor [10]. The system also comes ON during sunset and OFF during sunrise, and this action is controlled by light dependent resistor. This device was built around LDR, LM 555, Diode, BC 547, Relay, Voltage regulator, Bulb, Motion sensor, Resistor, Adapter.
