In this study, the proponents makes use solar energy to power up an automatic lighting system controlled by PIC microcontroller using assembly language in the program. The proponents used PIR motion sensor as a switch to turn on the lighting system, the motion sensor will send signal to the microcontroller to turn on the LED bulb by passing through the relay. The goal of the study is to design and develop an automatic lighting system with the help of a microcontroller, sensor, and relays, which is powered by solar energy.

— This paper presents the design of a solar tracking system driven by an AVR microcontroller. This project is done by two ways of tracking system, manual and auto tracking. This project is very useful for street light in the campus and villages. The solar panel converts the sun light into the electrical energy, because sun is a very good source of different energies. And the solar energy is the best technique for renewable energy. Basically the energy sources are two types such as conventional energy sources and non-conventional energy sources. Coal, petroleum, natural gas etc. are example of conventional energy sources and solar cell, fuel cells, thermo-electric generator, thermionic converter, solar power generation, wind power generation, geo-thermal energy generation etc. are example of non-conventional energy sources. In developing countries where electricity supplies are inadequate, renewable energy can offer an alternative to expensive extensions of the grid to sparsely populated or rural areas, or a contribution to the grid-based energy mix to meet rapidly expanding electricity demand in urban areas. This work presents an autonomous street lighting system based on solar energy as primary source, batteries as secondary source, and light emitting diodes as lighting source. This system is being presented as an alternative for remote localities, like roads and crossroads.

This Paper Presents a Microcontroller based Automated Intelligent Street lighting System which is utilized for power conservation, intelligence and fault detection. The main objectives are to automatically switch the street light to an ON/OFF state utilizing the Light Dependent Resistor, to save power and increment the life time of the LED utilizing Infrared Sensor(IR) to dim and brighten up the LED at intervals and to create a system where a fault is detected and a fault location message is sent to an assigned GSM number or control centre. This is achieved using a PIC18F26K22 microcontroller. The PIC microcontroller on the main board serves as the brain house of the system where every activity is coordinated from. The module used for lighting is the LED. The system automatically turns ON the light according to the degree of darkness and turns OFF the light according to the intensity of light. A Light Dependent Resistor (LDR) sensor, an Infrared Sensor (IR) and a GSM module are used for this research work. This system works at night. Street light will come to an ON state when the LDR senses a high degree of darkness but remains in a Dim state which is still bright enough for motorist to see clearly. Full ON is activated when movement is detected within the proximity of the IR but the Dim state is reactivated back after the movement is no longer sensed. The GSM module sends a fault detection message to a control centre or assigned GSM number stating the location of the faulty LED when a fault is detected with the LED or the LED does not come up. This design can save a considerable amount of Power because of the Dimming of the LED through the Infrared Sensor. However maintenance and personnel cost is reduced and lifespan of the LED is increased.

— This paper proposes energy efficient of automatic street lighting system based on low cost microcontroller. The main objective is to design energy efficient based controller for controlling the Light Emitting Diode (LED) based street lamp via appropriate lighting levels control. This system is consists of a microcontroller, light sensor, rain sensor, laser sensor and a set of the light emitting diode (LED) module. While, the controlling and managing of the system is based on the number of traffic and five different level of street light brightness has been used for lighting up the street and proportional to the number of traffic. The system was programmed to automatically turn off during the hours of daylight and only operate during the night and heavy raining or bad weather. Several numbers of tests have been conducted to test and validate the proposed prototype in the different environment. As conclusion, around 77%-81% reduction in power consumption can be achieved through this proposed automatic street lighting system for energy efficiency system design.

In this paper we present a way to reduce the standby power consumption of a PIR-sensor-based lighting device. Generally although a PIR-sensor-based lighting device will turn on when motion is detected, and will turn off when the motion disappears, the device still consumes 1-3 W power when the lampis off. In our design the device consumes 0.007 W when the light is off, and is not only easy to set up but also inexpensive. Our circuit supplies the lamp with power when motion is detected; when the motion disappears it turns the lamp off, and the electric power is shut off in order to reduce the standby power. We usean MCU which receives signals from a PIR sensor which detects any individual approaching the device. The MCU controls the SSR On/Off when used as a lighting switch for shutting off the standby power. The MCU monitoring program provides automatic detection of any individual by means of the PIR sensor. The MCU has internal modules to simplify the hardware circuit design. The c.

AbstractThe lack of natural light during night time in the urban environment has always been a problem. From people not being able to see where they are going, to the greater chance of being attacked or mugged at night which as we all know is a problem that has been in existence since humans started living together. The main advantage of this system exists in the reduction of costs related to energy consumption by the street light by integrating a vehicle/human detection algorithm into the system. The introduction of this vehicle/human detection algorithm further reduces the power consumption costs. In this project, solar PV is used to supply the energy to charge the battery. The battery later powers the operation of the whole system. The 1217V of the solar is buck to a steady 12V for battery charging. A light sensor is connected to the microcontroller that sense the light during day time, when the presence of day light is sensed the microcontroller turns ON the mosfet of the buck c.

This paper describes automatic lighting and security system design using PIR motion sensors. Using this sensor we can certainly minimize electrical power consumption and minimize cases of people forgetting to turn off the lights before they leave. The electricity crisis and the neglect of people to turn off lights is one of the most common problems in Indonesia, especially in the regions. With the help of sensors, we can eliminate these shortcomings by minimizing waste of electricity or saving the power produced. Using the motion received from any motion, the PIR sensor provides a high signal to the microcontroller. So we can easily create a program for the microcontroller to set the alarm. So this project is very low cost and also saves power. It also minimizes electricity bills from any office. What's more, this creates an opportunity to minimize the release of burdens in cities and villages.
