AUTOMATIC LIGHT CONTROL BY USING MICROCONTROLLER BASED LDR
This paper aims at designing and executing the advanced development in embedded systems for energy saving of lights. Nowadays, human has become too busy, and is unable to find time even to switch the lights wherever not necessary. The present system is like the lights will be switched on in the evening before the sun sets and they are switched off the next day morning after there is sufficient light on the outside. But the actual timing for these lights to be switched on are when there is absolute darkness. With this, the power will be wasted up to some extent. This paper gives the best solution for electrical power wastage. Also the manual operation of the lighting system is completely eliminated.
An Energy-efficient Microcontroller-based Smart Light Controlling System
2021
In this work, an energy-saving smart light controlling system has been proposed that can main-tain the desired intensity of light in a room automatically. Unlike the conventional light control system, the proposed system splits a large room into several zones and analyzes the light inten-sity of each zone; hence, the controlling unit adjusts the light intensity to the desired level. The main controlling unit consists of a light sensor, a motion sensor, a relay with a driver unit, an LCD display, etc. for controlling light efficiently to reduce the power waste. The sensors meas-ure the intensity of light, based on the standard light intensity data chart the controller units make a decision how many light bulbs are needed to be switched ON/OFF in a particular zone. Moreover, the system automatically switched-OFF all light bulbs when there is nobody in the room. Proteus design suite 8.0 is used to design and simulation of the proposed system. Moreo-ver, the PCB layout is designed using...
CONSTRUCTION OF AN INTELLIGENT AND EFFICIENT LIGHT CONTROL SYSTEM
A lighting control system is an intelligent connection of lighting that control the amount of light in a given space. It provides interaction between systems in order to regulate light. It is mostly used in public buildings in order to save energy maximally from lighting system and to satisfy codes of buildings. The problem of expensive cost in lighting system, increase in energy consumption bills and energy wastage led to the introduction of smart lighting. Therefore, an intelligent and efficient light control system that saves energy and cost of energy consumption of light in our day to day activities for rooms was assembled. Passive infrared sensor combined with the light dependent resistor was used to control the luminous intensity of led from the comparator (ATMEGA328) comparing the values gotten from the two sensors as input such that when the value of luminous intensity gotten from the light dependent resistor is higher than the required intensity, then the led remains off. When the value of luminous intensity gotten from the light dependent resistor is lower than the required intensity, the led supplies light that will make up for the missing intensity. It is deduced that, as the intensity of light increases, the resistance of the light dependent resistor decreases. It is also observed that the luminous intensity increases as the time of the day increases i.e. As the laboratory light intensity decreases. Thus, the system functions efficiently as the energy is considerably conserved.
Automatic room light intensity detection and control using a microprocessor and light sensors
IEEE Transactions on Consumer Electronics, 2008
In this paper we propose a design using both a microprocessor and light sensors for automatic room light detection and control. Our design, the HLCM (Home Light Control Module) which will be installed in every light fixture of a family, is made up of four blocks: the pyroelectric infrared (PIR) sensor circuit, the light sensor circuit, the microprocessor and the RF module. By using the PIR sensor circuit, the HLCM detects if a human body enters the detection area or not. If there is no human body present, all controlled lights are turned off. If there is, the HLCM detects the light intensity under the environment and maintains sufficient light by controlling the number of lights. We have also integrated an RF module to transmit and receive the data from each HLCM so we can control different lights in different regions. The result of using the HLCM shows that the total power consumption can be reduced.

Design and Implementation of LED Dimming System with Intelligent Sensor Module
An intelligent light emitting diode (LED) dimming system is designed and implemented for energy-saving lighting systems. An LED light bulb is powered by an LED driver controlled by a microcontroller using pulse width modulation (PWM) signals. By changing the duty cycle of the PWM signals, the LED driver generates a driving current of up to 1,000 mA. The current consumption by the LED light bulb exhibits a very linear characteristic that indicates that the level of LED dimming can be finely tuned. Multiple sensors-lighting intensity and ultrasonic range sensors-are combined with the LED dimming system to realize an automatically controllable LED lighting system. The light intensity sensor is capable of sensing ambient light. The ultrasonic range sensor can detect objects from 0.15 to 5.6 m at a resolution of 0.0254 m. The collected information by the light intensity and ultrasonic range sensors is processed by the microcontroller that in turn automatically controls the brightness of ...

At this crucial age of technological revolution, there is a widespread transition from the use of manually operated electronic devices to fully automatic electronic system. The concept of miniaturization has gained a broad scope of applications in the field of electronic engineering as high power gigantic gadgets and components are greatly diminished to a very small size with reduced power consumptions. The microcontroller which lies in the heart of the embedded system is a single chip computer which performs various control functions as required. This paper comprehensively explores the application of a PIC microcontroller in the continuous control of a room lighting system, by enhancing house owners with the ability to automatically control the Switch ON and Switch OFF actions of light in the room or apartment, when the movement of an occupant is electronically sensed. The sensor circuits effectively utilize the advancement in photonics to detect the presence of an occupant and responds in prominent manner. The design setup was simulated using the ISIS Proteus 8.0 simulation package and the installation recommendations were given in detail.
